Judge STRATJB dissents in a separate opinion.
JOSE A. CABRANES, Circuit Judge:
We consider here claims emerging from the re-drawing of the map of Europe following the defeat of the Axis Powers in the Second World War, the displacement of millions of people, particularly surviving Jews, in much of the continent, and the installation by force of governments in Central and Eastern Europe. See Michael R. Marrus, The Unwanted: Ewropean Refugees in the Twentieth Century 335-36 (1985) (describing the forced migration of Jews and expropriation of Jewish assets throughout Central and Eastern Europe following the Second World War); Compl. ¶ 3;1 see also Malcolm J. Proudfoot, European Refugees: 1989-5~, at 190 (1956) ("When the [Second World] IIW]ar ended, there were approximately 11 million non-German displaced persons in Europe who required repatriation."); id. at 189 (providing a breakdown by nationality of persons requiring repatriation).
Plaintiffs appeal from a judgment of the United States District Court for the Eastern District of New York (Edward R. Kor-man, Chief Judge) dismissing their claims against the Republic of Poland and the Ministry of the Treasury of Poland for lack of subject matter jurisdiction, pursuant to Federal Rule of Civil Procedure 12(b)(1). See Garb v. Republic of Poland, 207 F.Supp.2d 16 (E.D.N.Y.2002). Plaintiffs' claims, which at the pleadings stage we accept as true in all respects, see, e.g., Hallock v. Bonner, 387 F.3d 147, 150 (2d Cir.2004), arise from the mistreatment of Jews in Poland after the Second World War-mistreatment that Chief Judge Korman properly described as "horrendous." Garb, 207 F.Supp.2d at 17. In particular, plaintiffs challenge the Polish Government's expropriation of their property following the asserted enactment of post-war legislation designed for that purpose. Id. at 18.
As the District Court aptly noted, "strong moral claims are not easily converted into successful legal causes of action." Id. at 39 (internal quotation marks and alteration omitted.) Despite the severe injuries asserted by plaintiffs, the capacity of United States courts to exercise jurisdiction over plaintiffs' claims hinges on a legal inquiry narrowly circumscribed by statute. It is well settled that the only source of subject matter jurisdiction over a foreign sovereign in the courts of the United States is the Foreign Sovereign Immunities Act of 1976 ("FSIA"), 28 U.S.C. §~ 1330, 1602-1611, which codifies several exceptions to the long-established doctrine of foreign sovereign immunity.
Following a remand from the Supreme Court, see Republic of Poland v. Garb, 542 U.S. 901, 124 S.Ct. 2835, 159 L.Ed.2d 265 (2004), we consider for the second time whether plaintiffs' claims fall under these statutory exceptions. In the period between our previous disposition of this matter, see Garb v. Republic of Poland, 72 Fed.Appx. 850 (2d Cir.2003) (summary order), and the Supreme Court's remand, the question of the FSIA's retroactivity has been resolved in the affirmative, see Republic of Austria v. Altmann, 541 U.S. 677, 124 S.Ct. 2240, 159 L.Ed.2d 1 (2004). Accordingly, we now apply the FSIA ret[582]*582roactively to claims arising from events that took place prior to that statute’s 1976 enactment.
We hold that none of the FSIA’s exceptions to foreign sovereign immunity applies here and that subject matter jurisdiction is therefore lacking. First, we hold that plaintiffs have not satisfied the “commercial activity” exception of the FSIA, 28 U.S.C. § 1605(a)(2), because (a) a state’s confiscation of property within its borders is not a “commercial” act, (b) the subsequent commercial treatment of expropriated property is not sufficiently “in connection with” the prior expropriation to satisfy the “commercial activity” exception, and (c) we decline to credit plaintiffs’ recharac-terization of what are in essence “takings” claims as “commercial activity” claims. Second, we hold that plaintiffs have not satisfied the “takings” exception of the FSIA, 28 U.S.C. § 1605(a)(3), because (a) plaintiffs seek to recover property that is not “present in the United States,” (b) in such circumstances, plaintiffs must show that the property “is owned or operated by an agency or instrumentality of the foreign state,” (c) plaintiffs allege that the property is “owned by” the Ministry of the Treasury of Poland, Appellants’ Br. at 15, and (d) the Ministry of the Treasury of Poland is not an “agency or instrumentality” of the Republic of Poland because its “core function” is governmental rather than commercial.
Background
Plaintiffs are “Jewish persons and entities (and their heirs and successors) who owned real property ... in Poland during the period September 1, 1939 to May 30, 1945.” Garb, 207 F.Supp.2d at 19 (internal quotation marks omitted). They filed suit in the District Court on June 18, 1999, seeking redress from the Republic of Poland and the Ministry of the Treasury of Poland for expropriation of real property from Jews in post-War Poland. See id. at 17-19. The District Court’s thorough opinion sets forth plaintiffs’ claims in commendable detail, including the post-War violence perpetrated by the government of Poland against Polish Jews who had returned from the Soviet Union, the expropriation of property from those Jews, and the Polish government’s actual and constructive participation in that violence and expropriation. Id.
Because this suit sought to hold a foreign sovereign State liable in the courts of the United States, and because, under the FSIA, “a foreign state is presumptively immune from the jurisdiction of United States courts[J unless a specified [statutory] exception applies,” Saudi Arabia v. Nelson, 507 U.S. 349, 355, 113 S.Ct. 1471, 123 L.Ed.2d 47 (1993),2 plaintiffs have asserted that two exceptions to the FSIA apply to their claims — namely, (1) the “commercial activity” exception of 28 U.S.C. § 1605(a)(2),3 and (2) the “takings” exception of 28 U.S.C. § 1605(a)(3).4
[583]*583Defendants contested the applicability of those exceptions and moved to dismiss this action for lack of subject matter jurisdiction, pursuant to Federal Rule of Civil Procedure 12(b)(1). In a comprehensive opinion, the District Court granted defendants’ motion, see Garb, 207 F.Supp.2d at 39-40, finding that the “commercial activity” exception did not apply because, inter alia, (1) a government’s expropriation of property from its own citizens “is a quintessentially sovereign act and is never viewed as having commercial character,” id. at 31 (internal quotation marks omitted); and, in any event, (2) plaintiffs had failed to demonstrate, as required, that the assertedly commercial activity had a “direct effect” in the United States, id. at 32-33.
The District Court also concluded that plaintiffs could not rely on the “takings” exception to foreign sovereign immunity because (1) the FSIA’s “takings” exception could not be applied retroactively to hold a foreign sovereign liable for conduct that predates the 1976 enactment of the FSIA, id. at 25-30; and alternatively, even if the “takings” exception were to be applied retroactively, defendants would still enjoy sovereign immunity because (2) plaintiffs had not established that a State’s expropriation of property from its own nationals violates international law — a prerequisite for the application of the “takings” exception, id. at 33-34; and (3) the property in question is apparently neither “present in the United States” nor “owned or operated by an agency or instrumentality of the foreign state,” id. at 34-38.
The District Court granted defendants’ motion to dismiss in an order entered June 24, 2002, and plaintiffs timely filed a Notice of Appeal on July 19, 2002. We consolidated the appeal with Republic of Austria v. Whiteman, Nos. 02-9361 & 02-3087, for the purposes of oral argument.5
We heard oral argument on April 15, 2003, and, in light of a supervening and controlling decision by another panel of our Court in Abrams v. Société Nationale des Chemins de Fer Francais, 332 F.3d 173 (2d Cir.2003), we filed a summary order on August 6, 2003 vacating the District Court’s June 26, 2002 judgment (which had dismissed plaintiffs’ claims against Poland), see Garb, 72 Fed.Appx. at 855. Relying on Abrams, we stated that this “ease[ ] raises the threshold questions whether and on what terms the federal courts have jurisdiction under the [FSIA] to adjudicate the liability of sovereign states for conduct occurring prior to the statute’s enactment [in 1976].” Id. at 853. We explained, bound as we then were by Abrams, that whether the FSIA could be applied retroactively depended upon whether doing so “would have an impermissible ‘retroactive effect’ — that is, whether applying the FSIA would ‘impart rights a party possessed when he acted, increase a party’s liability for past conduct, or impose new duties with respect to [584]*584transactions already completed.’ ” Id. (quoting Abrams, 332 F.3d at 180-81).
As required by Abrams, we then remanded this case to the District Court to determine “the Department of State’s policy prior to [the enactment of the] FSIA with respect to sovereign immunity for Poland ... in the circumstances presented” here. Id. at 854. Defendants moved to stay the issuance of our mandate pending their petition to the Supreme Court for a writ of certiorari. We granted defendants’ request for a stay on September 10, 2003.
On June 14, 2004, the Supreme Court granted defendants’ petition for a writ of certiorari, vacated our judgment, and remanded this case to us “for further consideration in light of Republic of Austria v. Altmann, 541 U.S. 677, 124 S.Ct. 2240, 159 L.Ed.2d 1 (2004).” Republic of Poland v. Garb, 542 U.S. 901, 124 S.Ct. 2835, 159 L.Ed.2d 265 (2004).
Following the Supreme Court’s order, the parties and various amici curiae, including the United States, filed supplemental letter briefs with this Court concerning the post-Altmann disposition of this appeal. Although the legal views of the Executive concerning the proper scope of the FSIA statutory scheme are entitled to “no special deference,” such views are nevertheless of “considerable interest” to federal courts. Altmann, 541 U.S. at 701, 124 S.Ct. 2240. In addition to its views of the applicable legal standards, the United States’ letter brief informs us that, in this very case, “the foreign policy interests of the United States weigh against inferring the dramatic expansion of federal court jurisdiction that plaintiffs seek.” See Letter of Gregory G. Katsas, Jr., Deputy Assistant Attorney General, Department of Justice, and William H. Taft IV, The Legal Adviser, Department of State (Sept. 9, 2004) (“United States Supplemental Letter”), at 9 (emphasis added). Because, for the reasons stated below, we conclude that the District Court lacked subject matter jurisdiction to consider plaintiffs’ claims, we need not consider whether these claims should be dismissed in deference to the stated foreign policy interests of the Executive. See note 6, post.
Discussion
On remand, we are left to determine whether, in light of Altmann’s requirement of retroactive application of the FSIA, the District Court may properly exercise subject matter jurisdiction over .this case pursuant to either the FSIA’s “commercial activity” or “takings” exceptions to the long-established doctrine of foreign sovereign immunity. We hold that the District Court correctly found both exceptions inapplicable and therefore properly dismissed the complaint for lack of subject matter jurisdiction.6
I. The Effect of Altmann
In Altmann, the Supreme Court departed from what it termed a pre-existing “an-tiretroactivity presumption,” 541 U.S. at 696, 124 S.Ct. 2240, and held that the FSIA, including its exceptions, is applica[585]*585ble to conduct that preceded its enactment. The Court explained that because the doctrine of foreign sovereign immunity reflects “current political realities and relationships,” courts have traditionally “resolved questions of foreign sovereign immunity by deferring to the decisions of the political branches.” Id. (internal quotation marks omitted). The Court identified the FSIA as “the most recent such decision” and decided to defer to it — that is, to apply it retroactively — rather than to “presume” it inapplicable “merely because it postdates the conduct in question.” Id.
We have since interpreted Altmann as rendering unnecessary precisely the sort of investigation into pre-FSIA sovereign immunity doctrine that had been prescribed in our 2003 Abrams decision and required by our August 6, 2003 summary order in this case. See Abrams v. Société Nationale des Chemins de Fer Français, 389 F.3d 61, 63 (2d Cir.2004) (“After Altmann, it is no longer necessary to rely upon the State Department’s past determinations in ascertaining whether FSIA’s application to pre-enactment wrongdoing is impermissibly retroactive. Indeed, in its holding, the Supreme Court expressly disapproved of this historical approach .... ”). Accordingly, we hold that the FSIA applies here, and we thus consider whether plaintiffs have demonstrated that their claims fall under any exception to the FSIA’s presumption of sovereign immunity, see 28 U.S.C. § 1604; note 2, ante, such that these claims may be pursued in a United States court.
II. The Foreign Sovereign Immunities Act
In 1812, Chief Justice Marshall famously articulated the doctrine of absolute sovereign immunity, a doctrine deeply rooted in the principles of sovereign consent and reciprocity — concepts that form the touchstones of international law. Because a sovereign enjoys “full and complete power ... within its own territories,” and because “[t]he jurisdiction of courts is a branch of that which is possessed by the nation as an independent sovereign power,” the courts of the United States will not “degrade the dignity of [another] nation” by asserting jurisdiction over claims affecting the rights of the foreign sovereign, absent that sovereign’s consent. The Schooner Exchange v. McFaddon, 11 U.S. (7 Cranch) 116, 136-37, 3 L.Ed. 287 (1812). See generally Joseph W. Glannon & Jeffery Atik, Politics and Personal Jurisdiction; Suing State Sponsors of Terrorism Under the 1996 Amendments to the Foreign Sovereign Immunities Act, 87 Geo. L.J. 675, 691 (1999) (“As a practical matter, considerations of reciprocity compelled foreign sovereign immunity; nations expected to receive foreign sovereign immunity as well as to accord it. Chief Justice Marshall crystallized the thinking of the time in Schooner .... ”).
This general doctrine of absolute sovereign immunity survived until 1952, when the so-called Tate Letter enunciated as-United States policy a new, “restrictive” theory of sovereign immunity. See Letter of Jack B. Tate, Acting Legal Adviser, Department of State, to Acting Attorney General Philip B. Perlman (May 19, 1952), reprinted in 26 Dep’t of State Bull. 984, 984-85 (1952), and in Alfred Dunhill of London, Inc. v. Republic of Cuba, 425 U.S. 682, 96 S.Ct. 1854, 48 L.Ed.2d 301, app 2 at 711-15 (1976); see also Sugarman v. Aeromexico, Inc., 626 F.2d 270, 273-74 (3d Cir.1980) (reprinting the “core” of the Tate Letter). The Tate Letter proposed that “the immunity of the sovereign is recognized with regard to sovereign or public acts (jure imperii) of a state, but not with respect to private acts (jure gestionis).” Sugarman, 626 F.2d at 274. See generally William A. Dobrovir, A Gloss on the Tate Letter’s Restrictive Theory of Sovereign Immunity, 54 Va. L.Rev. 1 (1968) (describ[586]*586ing the Tate Letter’s “restrictive” theory of sovereign immunity).
When Congress enacted the FSIA in 1976, it intended to codify the Tate Letter. See Sugarman, 626 F.2d at 274 (“The Act was a codification of the Letter....”); see also H.R.Rep. No. 94-1487, at 7 (1976), reprinted, in 1976 U.S.C.C.A.N. 6604, 6605 (“[The FSIA] would codify the so-called ‘restrictive’ principle of sovereign immunity, as presently recognized in international law[, as] adopted by the Department of State in 1952 and ... [as] followed by the courts and by the executive branch ever since.”). Consistent with the Tate Letter, the FSIA specified “certain types of cases,” Sugarman, 626 F.2d at 274, in which immunity would not be afforded to a foreign sovereign. Those cases fall under, inter alia, the “commercial activity” exception, 28 U.S.C. § 1605(a)(2), and the “takings” exception, 28 U.S.C. § 1605(a)(3), to the foreign sovereign immunity recognized by the FSIA. In light of this background, we now consider whether either of those exceptions applies here.
III. The “Commercial Activity” Exception to Presumptive Foreign Sovereign Immunity (28 U.S.C. § 1605(a)(2))
Plaintiffs assert that the District Court may exercise jurisdiction over their claims pursuant to 28 U.S.C. § 1605(a)(2), see note 3, ante, the “commercial activity” exception of the FSIA. Under this provision, a plaintiff may establish an exception to the immunity of a foreign sovereign defendant if his claims are “based upon”
[1]a commercial activity carried on in the United States by the foreign state; or upon
[2] an act performed in the United States in connection with a commercial activity of the foreign state elsewhere; or upon
[3] an act outside the territory of the United States in connection with a commercial activity of the foreign state elsewhere and that act causes a direct effect in the United States[.]
28 U.S.C. § 1605(a)(2). Plaintiffs rely on the third of these three alternative grounds. Appellants’ Br. at 62.
As a threshold step in assessing plaintiffs’ reliance on the “commercial activity” exception, we must identify the act of the foreign sovereign State that serves as the basis for plaintiffs’ claims. The District Court found that, regardless of the subsequent commercial treatment of the expropriated property, plaintiffs’ claims are “based upon” the acts of expropriation.7 See Garb, 207 F.Supp.2d at 31 (“Plaintiffs’ claims ... are ‘based upon’ the manner in which the property was obtained, not its subsequent management.”). We agree with this description of plaintiffs’ claims. See Callejo v. Bancomer, S.A., 764 F.2d 1101, 1109 (5th Cir.1985) (explaining that to determine the basis of a claim, a court should focus on the “gravamen of the complaint”), cited with approval in Nelson, 507 U.S. at 357, 113 S.Ct. 1471; Garb, 207 F.Supp.2d at 19 (listing plaintiffs’ property-based claims).
We also agree with the District Court that the expropriations by defendants do not fall within the “commercial activity” exception of the FSIA. Expropriation is a decidedly sovereign — rather than commercial — activity.8 See, e.g., Hunt v. Mobil [587]*587Oil Corp., 550 F.2d 68, 73 (2d Cir.1977) (“Expropriations of ... property ... within the boundaries of the sovereign state are traditionally considered to be public acts of the sovereign removed from judicial scrutiny see also Alberti v. Empresa Nicaraguense de la Carne, 705 F.2d 250, 254 (7th Cir.1983) (recognizing that the nationalization of property is a “quintessential [government act”); Haven v. Rzeczpospolita Polska (Republic of Poland), 68 F.Supp.2d 947, 954 (N.D.Ill.1999) (“It is obvious that governmental expropriation of private property under governmental authority ... is the classic type of [sovereign, rather than commercial,] activity ....”)•
Moreover, plaintiffs’ property was not expropriated “in connection with a commercial activity of the foreign state.” The statutory term “in connection,” as used in the FSIA, is a term of art, and we interpret it narrowly. Accordingly, we have noted that “[a]cts are ‘in connection’ with ... commercial activity so long as there is a ‘substantive connection’ or a ‘causal link’ between them and the commercial activity.” Hanil Bank v. Pt. Bank Negara Indonesia (Persero), 148 F.3d 127, 131 (2d Cir.1998) (quoting Adler v. Fed. Republic of Nigeria, 107 F.3d 720, 726 (9th Cir.1997)); see also Drexel Burnham Lambert Group Inc. v. Comm. of Receivers for A.W. Galadari, 12 F.3d 317, 330 (2d Cir.1993) (declining to read “the ‘connection’ language of § 1605(a)(2) ... to include tangential commercial activities to which the ‘acts’ forming the basis of the claim have only an attenuated connection”).
Concededly, the expropriation of property from plaintiffs — indeed, from anyone who claims unlawful .taking of property— is, in some sense, “connected” to any subsequent commercial treatment of that property or its proceeds. Had there been no expropriation, there would 'have been no properties to treat in a commercial manner; in the circumstances presented here, Poland would have no properties to manage or sell. Such a connection, however, is simply too “attenuated,” and not substantive enough, to satisfy § 1605(a)(2). See Drexel, 12 F.3d at 330; see also Stena Rederi AB v. Comision de Contratos, 923 F.2d 380, 387 (5th Cir.1991) (holding that the “in connection with” requirement of the “commercial activity” exception was not satisfied where “the few commercial acts on which [the plaintiff] relies for its argument that [the defendant] has no sovereign immunity are unrelated to the facts on which [the plaintiff] relies for its causes of action”).
Our reasoning — that subsequent commercial transactions involving expropriated property do not give rise to subject matter jurisdiction over claims arising from the original expropriation — is consistent with Congress’s intention to deny sovereign immunity to foreign States only with respect to commercial, and not sovereign, acts. In recommending passage of the FSIA, the Report of the Judiciary Committee of the House of Representatives (“House Report” or “Report”) explained that the third clause of § 1605(a)(2) was intended to “embrace commercial conduct.” H.R.Rep. No. 94-1487, at 19 (1976), reprinted in 1976 [588]*588U.S.C.C.A.N. 6604, 6618 (emphasis added). Because, as noted above, a State’s exercise of its power to expropriate property within its borders is a decidedly sovereign act, it would undermine the express intent of Congress to deprive Poland of its sovereign immunity on “commercial activity” grounds.
Finally, we reject plaintiffs’ assertion that the “commercial activity” exception applies to their claims because this assertion simply recharacterizes plaintiffs’ “takings” argument. Federal courts have repeatedly rejected litigants’ attempts to establish subject matter jurisdiction pursuant to other FSIA exceptions when their claims are in essence based on disputed takings of property. The Fifth Circuit, for example, has held that a plaintiffs claim,
although sounding in tort [namely, a government’s “conversion” of property], is essentially a claim for an unjust taking of property_ Congress has provided an exception in Section 1605(a)(3) for takings of property that violate international law. We do not believe that Congress intended plaintiffs to be able to rephrase their takings claims in terms of [another FSIA exception] and thereby bring the claims even where the takings are permitted by international law.
De Sanchez v. Banco Central de Nicaragua, 770 F.2d 1385, 1398 (5th Cir.1985). The Ninth Circuit has agreed that when a claim is based on what is
in substance a taking of property .... it should be considered only under the takings exception of section 1605(a)(3). To hold otherwise would be to allow plaintiffs to escape the requirements of section 1605(a)(3) through artful rechar-acterization of their takings claims.
Chuidian v. Philippine Nat’l Bank, 912 F.2d 1095, 1106 (9th Cir.1990) (emphasis added); see also Alberti, 705 F.2d at 254 (holding that when the nationalization of a property — a “quintessential [government act” — is the basis of a claim, plaintiffs may not “transform th[e] governmental dispute into a commercial dispute” by reference to peripheral commercial activities about which there is no controversy); Garb, 207 F.Supp.2d at 33 (finding “commercial activity” exception inapplicable where “the activities allegedly causing a ‘direct effect’ in the United States ... have no legal significance to this action”). Accordingly, we hold that the District Court lacked subject matter jurisdiction over plaintiffs’ claims pursuant to the FSIA’s “commercial activity” exception and proceed to consider whether plaintiffs’ claims fall within the FSIA’s “takings” exception.
IV. The “Takings” Exception to Presumptive Foreign Sovereign Immunity (28 U.S.C. § 1605(a)(3))
To establish subject matter jurisdiction pursuant to the “takings” exception of the FSIA, a plaintiff must demonstrate each of four elements:
(1) that rights in property are at issue;
(2) that the property was “taken”;
(3) that the taking was in violation of international law; and either
(4)(a) “that property ... is present in the United States in connection with a commercial activity carried on in the United States by the foreign state,” or (4)(b) “that property ... is owned or operated by an agency or instrumentality of the foreign state and that agency or instrumentality is engaged in a commercial activity in the United States[.]”
28 U.S.C. § 1605(a)(3); note 4, ante; see also Zappia Middle E. Constr. Co. v. Emirate of Abu Dhabi, 215 F.3d 247, 251 (2d Cir.2000) (specifying criteria for the “takings” exception of the FSIA).
Defendants assert that plaintiffs have failed to satisfy several of these requirements. Appellees’ Br. at 32^40. We assume for the sake of discussion that [589]*589plaintiffs have satisfied the two threshold elements of the “takings” exception— namely, that rights in property are at issue here and that property was indeed taken. It is the third and fourth elements that, according to the District Court, pose the greatest obstacles to asserting subject matter jurisdiction over plaintiffs’ claims. Noting that “many of the plaintiffs appear to have been Polish citizens at the time of expropriation,” Garb, 207 F.Supp.2d at 33, the District Court reasoned that “ ‘no consensus existed’ on the issue whether the right to be free from the discriminatory and uncompensated taking of property was one of the ‘fundamental rights’ conferred by international law ‘upon all people vis-a-vis their own governments,’” id. at 34 (emphasis added) (quoting Filartiga v. Pena-Irala, 630 F.2d 876, 884-85, 888 n. 23 (2d Cir.1980) (citing Banco Nacional de Cuba v. Sabbatino, 376 U.S. 398, 425, 84 S.Ct. 923, 11 L.Ed.2d 804 (1964))). The District Court therefore concluded that a substantial legal “hurdle” must be overcome before plaintiffs can show that then-property was taken in violation of international law. See id. On appeal, plaintiffs maintain that “[t]he expropriation here was contrary to international law since it was discriminatory in nature, being aimed solely at Jews.” Appellants’ Br. at 15.
In the alternative, the District Court held that plaintiffs’ claims failed to meet the fourth element of the “takings” exception, because they have not shown that the property at issue is either (a) “present in the United States in connection with a commercial activity carried on in the United States by the foreign state,” or (b) “owned or operated by an agency or instrumentality of the foreign state and that agency or instrumentality is engaged in a commercial activity in the United States.” 28 U.S.C. § 1605(a)(3). The first of these alternative showings sets a higher threshold of proof for suing foreign states in connection with alleged takings by requiring that the property at issue be “present in the United States.” The amended complaint in this case defined the relevant properties as “real properties and improvements thereon in Poland.” Compl. ¶ 2 (emphasis added). Accordingly, the District Court concluded that “the property at issue here is in Poland.” Garb, 207 F.Supp.2d at 33. Because plaintiffs do not challenge this conclusion on appeal, they cannot rely on the first clause of the fourth element of § 1605(a)(3), which sets forth the conditions under which a plaintiff may assert takings claims against “foreign state[s].”
Rather, plaintiffs rely on the second clause of the fourth element, which permits a plaintiff to bring suit against an “agency or instrumentality of [a] foreign state,” provided that the agency or instrumentality “own[s] or operate[s]” the property in question and “is engaged in a commercial activity in the United States.” 28 U.S.C. § 1605(a)(3). The District Court concluded that, “as plaintiffs concede, the Republic of Poland is not an ‘agency or instrumentality’ of a foreign state,” because it is “the foreign state itself.” Garb, 207 F.Supp.2d at 34. Thus, the question before the District Court was whether the other defendant, Poland’s Ministry of the Treasury, “is, on the one hand, the foreign state itself or a subdivision of it, or, on the other hand, an ‘agency or instrumentality’ of the Republic of Poland and therefore potentially subject to jurisdiction under the second clause” of the fourth element of the “takings” exception. Id. at 34-35. In the circumstances of this case, the District Court doubted whether “the Ministry of the Treasury can be viewed as a legal entity separate from the Republic of Poland” and therefore held that “permitting the cause of action here would appear to undermine the immunity Congress intend[590]*590ed to confer on the Republic of Poland under the FSIA.” Id. at 38. On appeal, plaintiffs maintain that “[t]he Treasury is an agency and instrumentality of the Polish Government” within the meaning of § 1605(a)(3), Appellants’ Br. at 15, and therefore may be sued in United States courts.
Because we hold that the Ministry of the Treasury of Poland is not an “agency or instrumentality” of the Republic of Poland, plaintiffs’ claims fail to satisfy the fourth element of the “takings” exception, and we need not consider the questions of international law raised under the third element.9
a. “Agency or Instrumentality” Under the FSIA
The distinction between, on the one hand, agencies or instrumentalities of a foreign state, and, on the other hand, other organs or subdivisions of a foreign state, pervades the FSIA. For example, the statute provides that “a foreign state except for an agency or instrumentality thereof shall not be liable for punitive damages.” 28 U.S.C. § 1606 (emphasis added). Also, unlike the property of a foreign state generally, the property of an agency or instrumentality of a foreign state is subject to attachment or execution “regardless of whether the property is or was involved in the act upon which the claim is based.” 28 U.S.C. § 1610(b)(2).10
In order to satisfy the fourth element of the “takings” exception where, as here, the property at issue is located outside the United States, plaintiffs must show that the property they seek to recover is “owned or operated by an agency or instrumentality of the foreign state.” 28 U.S.C. § 1605(a)(3). An “agency or instrumentality of a foreign state” is a term of art to which the FSIA assigns a specific definition, namely “any entity”
(1) which is a separate legal person, corporate or otherwise, and
(2) which is an organ of a foreign state or political subdivision thereof,11 or a majority of whose shares or other ownership interest is owned by a foreign state or political subdivision thereof, and
(3) which is neither a citizen of a State of the United States as defined in [28 U.S.C. § 1332(c) and (e)] nor [591]*591created under the laws of any third country.
28 U.S.C. § 1608(b) (footnote added). Only the first criterion is contested here— namely, whether the Ministry of the Treasury of Poland is “a separate legal person, corporate or otherwise,” from the Republic of Poland.
In Transaero, Inc. v. La Fuerza Aerea Boliviana, 30 F.3d 148, 151 (D.C.Cir.1994), the Court of Appeals for the District of Columbia Circuit considered whether the Bolivian Air Force “count[ed] as a ‘foreign state’ or rather as an ‘agency or instrumentality’ ” of a foreign state for the purposes of 28 U.S.C. § 1608, which sets forth the FSIA’s service of process provisions. Compare 28 U.S.C. § 1608(a) (service “upon a foreign state or political subdivision of a foreign state”), ivith 28 U.S.C. § 1608(b) (service “upon an agency or instrumentality of a foreign state”). See also 28 U.S.C. § 1603(a) (providing that, “except as used in section 1608,” a “foreign state” includes its “agencies] or instru-mentalities]”). In reaching its disposition, the Transaero Court examined the background and legislative history of the FSIA and concluded that a foreign entity’s status as “a separate legal person” from a foreign state depends on “whether the core functions of the foreign entity are predominantly governmental or commercial.” Id. at 151. Applying this framework, the Court of Appeals in Transaero then determined that, under the FSIA, “armed forces are as a rule so closely bound up with the structure of the state that they must in all cases be considered as the ‘foreign state’ itself, rather than a separate ‘agency or instrumentality’ of the state.” Id. at 153.
The Fifth Circuit adopted Transaero’s “core functions” approach in another case concerning the FSIA’s service of process provisions, holding that “[wjhether an entity is a ‘separate legal person’ depends upon the nature of its ‘core functions’— governmental vs. commercial — and whether the entity is treated as a separate legal entity under the laws of the foreign state.” Magness v. Russian Federation, 247 F.3d 609, 613 n. 7 (5th Cir.2001).12
While neither Transaero nor Magness directly concern the amenability-to-suit of an alleged “agency or instrumentality of a foreign state” under 28 U.S.C. § 1605(a)(3), we nonetheless regard Transaero as instructive because, prior to invoking “ease of administration” as “a final reason” to prefer its “core functions” approach,13 the Transaero Court analyzed Congress’s broader use of the phrase “agency or instrumentality of a foreign state” in light of “a rich background of federal and international law,” including (1) the emergence of the “restrictive” theory of sovereign immunity, which differentiates between the public and commercial acts of foreign states, (2) the venue provisions of 28 U.S.C. § 1391, which permit parties to bring suit against an “agency or instrumentality” “in any judicial district in which the agency or instrumentality is licensed to do business or is doing business,” and (3) language used in [592]*592the enabling charters of governmental corporations, both in the United States and abroad. Transaero, 30 F.3d at 151-52.14
Indeed, our Circuit has already relied on the reasoning of Transaero (as well as on the reasoning of the District Court in this case) outside the context of the FSIA’s service of process provisions. See, e.g., Compagnie Noga D’Importation Et D’Exportation S.A. v. Russian Fed’n, 361 F.3d 676, 688 (2d Cir.2004). In Compagnie Noga — -which concerned the confirmation and enforcement of arbitral awards under the Convention on the Recognition and Enforcement of Foreign Arbitral Awards, June 10, 1958, 21 U.S.T. 2517, 330 U.N.T.S. 53 (“Convention”) — we found “no meaningful legal distinction ... between a sovereign and one of its political organs,” Compagnie Noga, 361 F.3d at 688, and therefore concluded that “the Russian Federation and the Government [of Russia] are not separate ‘parties’ for the purposes of confirming and enforcing an arbi-tral award under” the Convention, id. at 690. We reached this conclusion partly by relying on Transaero as an authoritative restatement of “federal common-law principles.” 15 Id. at 688.
[593]*593On at least one occasion, the District of Columbia Circuit has applied the “core functions” principle of Transaero to determine whether a governmental ministry may be sued in U.S. courts pursuant to 28 U.S.C. § 1605. See Roeder v. Islamic Republic of Iran, 333 F.3d 228, 234 (D.C.Cir.2003). Although the Roeder Court considered whether Iran’s Ministry of Foreign Affairs could be sued in its capacity as an “official, employee, or agent ” of a foreign state, pursuant to 28 U.S.C. § 1605(a)(7) (emphasis added), and did not contemplate the meaning of “agency of instrumentality” as defined at 28 U.S.C. § 1603(b), it nonetheless relied upon Transaero to reach its conclusion that “the Ministry of Foreign Affairs [of Iran] must be treated as the state of Iran itself rather than as its agent.” Roeder, 333 F.3d at 234.16
Because we are persuaded by Transae-ro ’s analysis of legislative and international law sources,17 and because this Circuit [594]*594and others have already applied Transae-ro ’s reasoning in analogous contexts, we apply Transaero to the facts here and inquite “whether the core functions” of the Ministry of the Treasury of Poland “are predominantly governmental or commercial.” Transaero, 30 F.3d at 151.
b. The Ministry of the Treasury of Poland Is Not an “Ayency or Instrumentality ”
Applying the Transaero standard to the circumstances of this case, the District Court concluded that “[t]he Ministry of the Treasury would appear to be an integral part of Poland’s political structure, and its core function — to hold and administer the property of the Polish state — is indisputably governmental.” Garb, 207 F.Supp.2d at 35. We agree.
The 1997 Constitution of the Republic of Poland provides for a Council of Ministers charged with conducting the Republic’s “internal affairs and foreign policy.” The Polish Constitution: Text and Introduction 86 (R. van der Wolf ed., 2000) (translating Pol. Const. art. 146) (“The Polish Constitution ”). One recent study of Poland’s government describes the operation of the country’s ministers and ministries as follows:
Ministers are individually accountable to the Sejm [ie., the lower house of the Polish parliament] for their departmental responsibilities and can face votes of no confidence.... Ministers may, but do not have to be, parliamentarians (as in the British case) but if they are they do not have to resign their seats (as in France). They are assisted in running their ministries by secretaries and under-secretaries of state, appointed by the prime minister on their proposal and whose numbers vary according to the ministry. Since 1996, they have been divided into politically nominated figures — who compose their political cabinet who resign along with ministers— and administrative ones who remain, and who are encouraged to behave as civil service functionaries. Administrative structures were standardized in the 1999 reform and ministries all now have the minister’s political cabinet along with ten identical organizational units. Ministers can issue orders (zarzadzen-ie) but, unlike prime ministerial regulations, they are only binding internally, within their own ministries.
George Sanford, Democratic Government in Poland: Constitutional Politics Since 1989, at 164 (2002).18
Among the functions of the Council of Ministers enumerated in Poland’s constitution is the “protect[ion of] the interests of the State Treasury.” The Polish Constitution at 86 (translating Pol. Const. art. 146). Defendants have submitted to the District Court a translation of Article 3.2 of Poland’s Law of August 8, 1996 on [595]*595Exercise of State Treasury Powers, which provides that “[t]he State Treasury, represented by the Minister of the State Treasury, is vested with property rights to state-owned assets, unless separate regulations specify that [anjother state legal entity is vested with such rights.” J.A. at 235. In addition, defendants supplied an affidavit from Leslaw Kostórkiewicz, a former assistant professor of law at the Warsaw Law School and former Director of the Legal Office of the Polish Senate. See Kostórkiewicz Aff ¶2, J.A. at 225. The affidavit states, in relevant part:
The Ministry is part of the central government of Poland and exists to act on behalf of the Republic of Poland. By statute, the Ministry manages property, including land, on behalf of the Polish State. It does not hold property separately from the Polish State. The Ministry also represents the Polish State with respect to financial claims brought against the State.
Kostórkiewicz Aff. ¶ 16, J.A. at 230.
Upon review of this evidence, and the full record before us, we find no error in the District Court’s finding that the Ministry of the Treasury of Poland is “an integral part of Poland’s political structure” and that the Ministry’s “core function... is indisputably governmental” rather than commercial. Garb, 207 F.Supp.2d at 35.19
On appeal, plaintiffs assert that “[t]he District Court’s conclusion is clearly at odds with the legislative history of the FSIA,” relying principally on two passages from the House Report. Appellants’ Br. at 55-56. We are not persuaded by plaintiffs’ reading of the Report.
First, the House Report explains that the requirement that an “agency or instrumentality” be a “separate legal person, is intended to include a corporation, association, foundation, or any other entity which, under the law of the foreign state where it was created, can sue or be sued in its own name, contract in its own name or hold property in its own name.” H.R.Rep. No. 94-1487, at 15, reprinted in 1976 U.S.C.C.A.N. at 6614. Plaintiffs argue that the Ministry of the Treasury of Poland falls squarely under this definition because, as Kostórkiewiez’s affidavit concedes, the Ministry is “not immune from suit in Poland.” Kostórkiewicz Aff. ¶ 4, J.A. at 226.
The Transaero Court properly cautioned against reading the Report’s passage in the manner suggested by plaintiffs. Because “any nation may well find it convenient (as does ours) to give powers of contract and litigation to entities that on any reasonable view must count as part of the state itself,” giving dispositive weight to such powers would extend the definition of “agencies or instrumentalities” “well beyond” the “public commercial enterprises” that Congress apparently intended to target. Transaero, 30 F.3d at 152.
[596]*596Moreover, contrary to plaintiffs’ contention, the House Report is, at best, ambiguous on the issue at hand. If the passage invoked by plaintiffs suggests that the Ministry of the Treasury of Poland is an “agency or instrumentality” of the Republic of Poland, other statements in the House Report point in the opposite direction. For example, the passage quoted by plaintiffs is preceded by the following statement:
[T]he term “foreign state” as used in every section [of the FSIA besides that codified at 28 U.S.C. § 1608] includes not only the foreign state but also political subdivisions, agencies and instru-mentalities of the foreign state.20 The term “political subdivisions” includes all governmental units beneath the central government, including local governments.
H.R.Rep. No. 94-1487, at 15, reprinted in 1976 U.S.C.C.A.N. at 6613 (footnote added). This suggests that all governmental units beneath the central government— and the Ministry of the Treasury is indisputably one such unit — constitute “political subdivisions,” a category that is not congruent with “agencies and instrumentalities.” Thus, the House Report, read as a whole, offers at best conflicting indications about the Ministry’s status.21
[597]*597Second, plaintiffs draw our attention to the House Report’s statement that “[a]s a general matter, entities which meet the definition of an ‘agency or instrumentality of a foreign state’ could assume a variety of forms, including ... a department or ministry which acts and is suable in its own name.” H.R.Rep. No. 94-1487, at 15-16, reprinted in 1976 U.S.C.C.A.N. at 6614. This passage certainly suggests that a ministry may constitute an “agency or instrumentality” within the meaning of the FSIA, but it by no means indicates that a ministry must constitute an “agency or instrumentality” under that statute.22 Plaintiffs point to no court that has held that a ministry qualifies as an “agency or instrumentality” under the FSIA, and at least two federal appellate courts have reached the opposite conclusion. See Roeder, 333 F.3d at 234 (holding that, pursuant to the reasoning of Transaero, “the Ministry of Foreign Affairs must be treated as the state of Iran itself rather than as its agent”); Magness, 247 F.3d at 613 n. 7 (holding that “the Russian Ministry of Culture is governed by § 1608(a),” which sets forth requirements for service upon foreign states, “while the Russian State Diamond Fund is a separate legal entity governed by § 1608(b),” which sets forth requirements for service upon agencies or instrumentalities of foreign states).23 In short, the District Court’s reasoning is not contradicted by the legislative history of the FSIA.24
[598]*598We therefore hold that the Ministry of the Treasury of Poland is not “an agency or instrumentality” of the Republic of Poland within the meaning of the FSIA. Accordingly, plaintiffs have not satisfied the fourth element of the FSIA “takings” exception to foreign sovereign immunity.
Conclusion
For the reasons stated above, we hold that:
(1) Altmann requires us to apply the FSIA, and its exceptions, to claims based on conduct that predates the 1976 enactment of the FSIA;
(2) plaintiffs have not. satisfied the “commercial activity” exception of the FSIA, 28 U.S.C. § 1605(a)(2), because (a) a state’s confiscation of property within its borders is not a “commercial” act, (b) the subsequent commercial treatment of expropriated property is not sufficiently “in connection with” the prior expropriation to satisfy the “commercial activity” exception, and (c) we decline to credit plaintiffs’ recharacterization of what are in essence “takings” claims as “commercial activity” claims; and
(3) plaintiffs have not satisfied the “takings” exception of the FSIA, 28 U.S.C. § 1605(a)(3), because (a) plaintiffs seek to recover property that is not “present in' the United States,” and (b) plaintiffs fail to show that the property “is owned or operated by an agency or instrumentality of the foreign state” within the meaning of the FSIA.
Accordingly,, we affirm the judgment entered by the District Court granting defendants’ motion to dismiss the action for lack of subject matter jurisdiction.
