Plaintiff-appellant, Ursula Ungaro-Be-nages, filed suit against two German banks, Dresdner Bank and Deutsche Bank, to recover assets from her family’s estate. The plaintiff alleges that the banks, through the Nazi Regime’s program of “Aryanization,” stole her family’s interest in its manufacturing company, Orenstein & Koppel (“O&K”). The district court granted summary judgment for the defendant banks on multiple grounds, including the political question doctrine, international comity, statute of limitations and failure to state a claim. For the reasons that follow, we affirm the decision of the district court.
1. Background
A. The History of the Orenstein’s Interests in O&K
In 1876, the plaintiffs great-grandfather, Benno Orenstein, together with Arthur Koppel, created O&K, which became Germany’s sixth largest manufacturer of machinery. The company produced heavy earth-moving equipment and railway lines. 1 Benno Orenstein was the Director General of O&K until his death in 1926, when his son, Alfred Orenstein, became Managing Director. At this time, the Or-enstein family’s shares of O&K were distributed equally among Benno Orenstein’s four children, although members of the family were not permitted to sell the shares without Alfred Orenstein’s permission for ten years. Ungaro-Benages alleges that the family maintained a controlling interest in the company, including hundreds of thousands of preferred shares and common shares. 2
*1230 Ungaro-Benages does not have precise information on what happened to the O&K shares once the Nazi party came to power. She alleges that because the Orensteins were Jewish, their ownership in O&K was vulnerable to “Aryanization,” a state-instituted program in which Jewish assets were transferred to non-Jews by way of “boycotts, force, terror and coercion.” Jewish owners were ousted from the boards of German corporations and assets were sold to non-Jews at nominal values. German banks, including the defendants in this action, acted as “trustees” for Jewish assets and aided the German government in transferring these assets away from their Jewish owners. The plaintiff alleges that both defendant banks were voluntarily involved in and profited from the state practice of Aryanization. She further alleges that the defendant banks continue to this day to conceal documentary evidence of their actions.
In the case of O&K, Ungaro-Benages alleges that Dresdner Bank, with the assistance of Deutsche Bank, successfully ousted the Orensteins from their positions on the board and effectively stole their stock. In her initial complaint, she maintains that the Nazi government and the Dresdner Bank “pressured and coerced” the Oren-stein family into an agreement whereby Erich Niemann, a Dresdner Bank managing director, took over day-to-day control of O&K and became a trustee for all of the Orenstein’s shares of preferred and common stock. Niemann was replaced by Karl Rasche, another Dresdner Bank representative in 1935. By 1938, all of the Jewish members of O&K’s board, as well as the boards of both banks, had been removed, and Alfred Orenstein had relocated to South Africa to manage the company’s branch there. O&K later terminated its contract with Alfred Orenstein. The plaintiff alleges that, by 1943, Deutsche Bank owned two-thirds of all O&K shares and had completely divested the Oren-steins of their interests in the company. There is only one record of any payment to an Orenstein family member for shares of stock: 37,943RM to Alfred Orenstein.
B. Ungaro-Benages''’s Connection to O&K
Each of Benno Orenstein’s four children received an equal share of the family’s O&K stock upon his death. One of Ben-no’s daughters, Lili, married and had two daughters, Ursula (“Ulla”) and Liselotte. Ulla had a son, Peter Ungaro, and a daughter, Ursula Ungaro-Benages (the plaintiff). Liselotte had no heirs and left all of her assets to her sister (Ulla), Peter, and Ursula. The plaintiff now claims to represent, along with her brother, one-quarter of the estate of Benno Orenstein. The plaintiff only learned in 1993 that she was of Jewish descent. She did not discover until 2001 that she was the great-granddaughter of Benno Orenstein. Her grandmother, Lili Orenstein Berliner, did know about the family’s history and attempted to ascertain what had happened to her interest in O&K. In 1950, Lili Berliner, through an attorney, wrote to Deutsche Bank requesting an accounting of her assets. Apparently Lili Berliner and her attorney took no further action. The plaintiff maintains that the bank did not provide any information and alleges that it still has failed to account for the assets.
C. The International Agreements Addressing WWII Claims
After the end of WWII, there were several international agreements addressing restitution and reparations. In its sector of occupied Germany, the United States enacted military laws requiring that property taken by the Nazi Regime be restored and providing that individuals could bring claims for restitution of identifiable property. In 1954, the United States govern *1231 ment, together with the British and French governments, entered into an agreement to unite their sectors into an independent West German government. See Termination of the Occupation Regime in the Federal Republic of Germany, Oct. 23, 1954, 6 U.S.T. 4117. This agreement reaffirmed Germany’s obligation to provide restitution as prescribed by United States’ military law. 3
In addition to claims by German nationals, the West German government also faced claims based on its wartime activities by other governments and foreign nationals. Many of the post-war treaties called for reparations, but the 1953 London Debt Agreement-an effort by Western powers to reindustrialize West Germany to help fight the Cold War-suspended these obligations. The suspension of claims was viewed as a suspension of the reparations question until a final post-war treaty on Germany was concluded, which did not occur until 1990 when Germany was reunified. In the 1990s, class-action lawsuits against the German government and private German companies increased dramatically in American courts, which caused considerable concern in Germany. In an effort to stem American litigation, the German government sought to enter into an international agreement with the United States to remove this litigation to an alternative forum based in Germany.
In 2000, President Clinton entered into an agreement with the German government (“the Foundation Agreement”) aimed at achieving a “legal peace.” 4 See Agreement concerning the Foundation “Remembrance, Responsibility and the Future,” July 17, 2000, U.S.-F.R.G., 39 I.L.M. 1298. In the agreement, the German government agreed to establish a private foundation, the Foundation “Remembrance, Responsibility, and the Future” (“the Foundation”), to hear claims brought by victims of the Nazi regime. 5 The Foundation is funded by voluntary contributions from the German government and German companies. Both the United States government and the German government argue that this fund offers compensation to victims of the Nazi regime that would not be available through traditional litigation.
In return, the United States agreed to encourage its courts and state governments to respect the Foundation as the exclusive forum for claims from the National Socialist era. The agreement, however, did not suspend or transfer lawsuits in American courts to Germany. Instead, the United States promised to file a Statement of Interest in any lawsuit dealing with WWII restitution or reparations. 6 *1232 The statement would inform United States courts that it is in the foreign policy interests of the United States for the case to be dismissed on any valid legal ground but would not suggest that the agreement itself provides an independent legal basis for dismissal.
II. Discussion
The district court dismissed the case on five grounds: (1) non-justiciable political question, (2) international comity, (3) statute of limitations, (4) failure to state a claim on which relief can be granted, 7 and (5) a lack of capacity to sue. 8 The district court rejected the defendants’ assertion that the act of state doctrine was another independent ground for dismissal. We affirm the district court’s opinion based on international comity.
A. Federal Common Law of Foreign Affairs
At the outset, we need to specify the source of law governing the present claim. We hold that federal law, rather than Florida law, governs notwithstanding the fact that the plaintiff brought state law claims against the defendant banks.
Under the
Erie
doctrine, a federal court adjudicating state law claims applies the substantive law of the state.
See Erie R.R. Co. v. Tompkins,
We could perhaps in this diversity action avoid the question of deciding whether federal or state law is applicable to this aspect of the litigation....
‡ ^
However, we are constrained to make it clear that an issue concerned with a basic choice regarding the competence and function of the Judiciary and the National Executive in ordering our relationships with other members of the international community must be treated exclusively as an aspect of federal law. It seems fair to assume that the Court did not have rules like the act of state doctrine in mind when it decided Erie R. Co. v. Tompkins. Soon thereafter, Professor Philip C. Jessup, now a judge of the International Court of Justice, recognized the potential dangers were Erie extended to legal problems affecting international relations. He cautioned that rules of international law should not be left to divergent and perhaps parochial state interpretations.
Here, the federal government has engaged in years of state-to-state negotiations and, in 2000, concluded an executive agreement with the German government addressing litigation arising from the National Socialist era. In addition, the Supreme Court determined that this agreement preempts any contrary state law because such state laws would interfere with the President’s foreign affairs power.
See Am. Ins. Ass’n v. Garamendi,
B. The Foundation Agreement
To resolve the present litigation, we begin by examining the Foundation Agreement, the agreement between the United States and Germany. 9 The plain *1234 tiff argues that the agreement does not cover her suit because the relevant transactions took place before World War II, but the treaty’s scope includes any actions committed during the National Socialist era. Article 1 states:
The parties agree that the Foundation “Remembrance, Responsibility and the Future” covers, and that it would be in their interests for the Foundation to be the exclusive remedy and forum for the resolution of, all claims that have been or may be asserted against German companies arising from the National Socialist era and World War II.
Foundation Agreement, art. I, para. 1, 39 I.L.M. at 1299 (emphasis added). Furthermore, the agreement explicitly covers property claims. In Annex B, the United States government agreed to submit a statement of interest to federal courts announcing that the Foundation is the preferred forum for “the resolution of all asserted claims against German companies arising from their involvement in the National Socialist era and World War II, including without limitation those relating to ... damage to or loss of property, including banking assets and insurance policies.” Foundation Agreement, Annex B, para. 1, 39 I.L.M. at 1303 (emphasis added). 10
The Foundation Agreement, however, does not provide the substantive law to resolve the case before us because it neither settles the outstanding claim nor directs that all claims be transferred to the Foundation’s settlement procedures. Rather, the United States simply promises to announce that such a transfer is in the United States’ national interests. In Annex B, the United States government is obliged to inform domestic courts that its policy interests “favor dismissal on any valid legal ground,” but “does not suggest that its policy interests concerning the Foundation in themselves provide an independent legal basis for dismissal.” Foundation Agreement, Annex B, para. 7, 39 I.L.M. at 1304. Thus, by its own terms, the agreement does not provide a basis to dismiss or suspend litigation against German companies stemming from their actions during the National Socialist era.
Because the Foundation Agreement firmly establishes that issues related to litigation against German corporations from the National Socialist era are gov *1235 erned by federal law, but does not provide any substantive principles by which to adjudicate this case, we must examine federal law not based in treaty to resolve the issues presented here.
In the following sections, we first determine that the case is justiciable. Although the case has implications for our foreign relations, our consideration of the claim is not barred by the political question doctrine. Second, based on the principle of international comity, we defer to the tribunal created by the Foundation Agreement to adjudicate the issues raised here.
C. The Political Question Doctrine
The district court found that this case implicates American foreign relations and, thus, is a political question, non-justi-ciable in domestic courts. We disagree.
The political question doctrine is based on the proper relationship between the judiciary and the political branches of government.
Baker v. Carr,
is found a textually demonstrable constitutional commitment of the issue to a coordinate political department; or a lack of judicially discoverable and manageable standards for resolving it; or the impossibility of deciding without an initial policy determination of a kind clearly for nonjudicial discretion; or the impossibility of a court’s undertaking independent resolution without expressing lack of the respect due coordinate branches of government; or an unusual need for unquestioning adherence to a political decision already made; or the potentiality of embarrassment from multifarious pronouncements by various departments on one question.
Id.
at 217,
Issues related to foreign affairs often are beyond the competence of the federal courts to resolve because they require judicial intervention in policy areas reserved to the political branches or could express a lack of respect due the other branches. Yet not all issues that could potentially have consequences to our foreign relations are political questions. As the Supreme Court stated in
Baker v. Carr,
“it is error to suppose that every case or controversy which touches foreign relations lies beyond judicial cognizance.”
Id.
at 211,
Here, none of the factors that advise against judicial resolution are present. Adjudication of the present claim would not interfere with the executive’s handling of foreign relations or show a lack of respect to the executive’s power in foreign affairs. Indeed, the plain text of the Foundation Agreement anticipates that federal courts will consider claims against German corporations. The entirety of Annex B of the agreement is dedicated to explaining what the United States government will include in its Statement of Interest to American courts hearing these cases. Furthermore, the agreement itself provides that it does not provide an independent legal basis for dismissal. See Foundation Agreement, Annex B, para. 7, 39 I.L.M. at 1304. Thus, the executive opted not to settle these claims or to transfer the claims to the Foundation, although it had the power to do so. 11
*1236
As a result, federal court consideration of the present case does not reflect a lack of respect for the executive nor does it interfere with American foreign relations. The United States is in full compliance with the Foundation Agreement so long as it files a statement of interest to courts urging respect for the Foundation as the exclusive forum to resolve these claims. This statement of interest from the executive is entitled to deference and we give the executive’s statement such deference in our international comity analysis.
See Republic of Austria v. Altmann,
— U.S. —,
The other four factors similarly do not lead us to conclude that the issue raised here is a political question. First, the issues addressed in the present litigation are not constitutionally committed to a coordinate political branch. The present litigation against two foreign corporations is subject to the political question analysis only because the executive has entered into international negotiations over this *1237 topic. Thus, the courts should look to the results of those negotiations to determine if judicial resolution of the claim would interfere with the executive’s conduct of foreign relations. The Foundation Agreement is unambiguous in its expectation that federal courts will consider these cases and should dismiss them based on ordinary principles of federal law. Annex B states:
Plaintiffs in these [Nazi era] cases face numerous legal hurdles, including, without limitation, justiciability, international comity, statutes of limitation, jurisdictional issues, forum non conveniens, difficulties of proof, and certification of a class of heirs. The United States takes no position here on the merits of the legal claims or arguments advanced by plaintiffs or defendants. The United States does not suggest that its policy interests concerning the Foundation in themselves provide an independent legal basis for dismissal, but will reinforce the point that U.S. policy interests favor dismissal on any valid legal ground.
See Foundation Agreement, Annex B, para. 7, 39 I.L.M. at 1304 (emphasis added). The President could have settled these cases. In that case, federal courts would be interfering with the executive’s conduct of foreign relations if we continued to exercise jurisdiction. Such is not the situation here. The President has purposefully chosen not to settle these claims directly and, instead, has instructed the federal courts to use existing legal grounds.
Second, consideration of the present case will not lead to multifarious pronouncements that could potentially embarrass the executive. Quite the opposite, the governments anticipated that federal courts would consider cases against the German government or German corporations. Third, the issues raised here can be resolved through judicially discoverable and manageable standards. Federal courts adjudicate claims against foreign corporations every day and can consider the nation’s foreign policy interests and international comity concerns in their decisions. Finally, adjudication of the present case does not require the courts to make a policy determination.
■D. International Comity
International comity reflects “the extent to which the law of one nation, as put in force within its territory, whether by executive order, by legislative act, or by judicial decree, shall be allowed to operate within the dominion of another nation.”
Hilton v. Guyot,
The doctrine of international comity can be applied retrospectively or prospectively. When applied retrospectively, domestic courts consider whether to respect the judgment of a foreign tribunal or to defer to parallel foreign proceedings.
See, e.g., Finanz AG Zurich v. Banco Economico S.A.,
When applied prospectively, domestic courts consider whether to dismiss or stay a domestic action based on the interests of our government, the foreign government and the international community in resolving the dispute in a foreign forum.
See Bi v. Union Carbide Chems. & Plastics Co.,
The analysis for both forms of international comity embody similar concerns with foreign governments’ interests, fair procedures, and American public policy, but they emphasize different issues. When applied retrospectively, federal courts evaluate three factors: (1) whether the foreign court was competent and used “proceedings consistent with civilized jurisprudence,” (2) whether the judgment was rendered by fraud, and (3) whether the foreign judgment was prejudicial because it violated American public policy notions of what is decent and just.
Turner Entm’t,
Applied prospectively, federal courts evaluate several factors, including the strength of the United States’ interest in using a foreign forum, the strength of the foreign governments’ interests, and the adequacy of the alternative forum.
See Jota,
Here, we decide to abstain based on the strength of our government’s interests in using the Foundation, the strength of the German government’s interests, and the adequacy of the Foundation as an alternative forum. The United States government has consistently supported the Foundation as the exclusive forum for the resolution of litigation against German corporations related to their acts during the National Socialist era. The President entered into negotiations with the German government and determined that the interests of American citizens, on the whole, would be best served by establishing the Foundation Agreement.
14
The agreement offers monetary compensation to nationals who were used as slave labor and were victims of insurance fraud as well as those deprived of their property. The fund to provide this compensation was established with the expectation that all such American litigation against German corporations would be resolved at the Foundation. In creating a comprehensive compensatory scheme for all remaining victims of the Nazi era, the Foundation Agreement may end up favoring the monetary interests of some American victims more than others. International agreements, however, often favor some domestic interests over others, and the President has the constitutional authority to settle the international claims of American citizens, even if the claimants would prefer litigation in American courts.
See Garamendi,
Furthermore, the Foundation is an adequate alternative forum. The tribunal has a specialty in the relevant post-war law and has relaxed standards of proof to ease the burden for the potential plaintiffs to obtain compensation. The Foundation offers victims of the Nazi era an adequate remedy, even if the Foundation cannot provide as substantial an award as American courts.
See Piper Aircraft Co. v. Reyno,
The plaintiff maintains that the forum does not provide her with a remedy because her claims are barred under the Foundation Agreement. Our reading of the Foundation Agreement, however, does not lead us to the conclusion that her claims necessarily would be barred. Annex A of the agreement specifically addresses claims of deprivation of property by German companies based on discrimination. 15 That provision provides that the *1240 plaintiffs claims would be barred if her family could have received compensation under the German restitution laws. The plaintiff is free to argue to the Foundation, just as she has argued to this court, that her claims should not be barred because the defendant banks prevented her family from pursuing their property claims after the war. The Foundation is in just as good a position as this court to consider the allegedly fraudulent acts by the defendant banks and is likely to be far more familiar than this court with German law on the relevant issues.
Moreover, if we did not abstain on international comity grounds, we would have to address whether the plaintiffs claim is barred under American law based on the statute of limitations. The plaintiffs grandmother, from whom the plaintiffs claim is derivative, began proceedings to recover her family’s assets in 1950 but then failed to pursue her claim. The district court, applying German law, found that the plaintiffs claim was time barred. We do not reach the issue because we defer to the Foundation, but note the plaintiff faces similar hurdles in federal court to those she would face at the Foundation.
We recognize that the plaintiff would prefer to pursue her claim in federal court. She is an American citizen, and even though her claim is derivative of her grandmother, we give particular attention to her choice of forum. On balance, however, we find that the strength of the interests held by the American government and the German government outweigh the plaintiffs preference. In doing so, we note that American and German governments have entered into extensive negotiations over this subject and those negotiations affect thousands of other victims of the Nazi regime. While we do not use the Foundation Agreement as an independent legal basis to dismiss this case, we must take the governments’ ongoing interests in settling claims from the National Socialist era and World War II into account in our international comity analysis. We further note that all of the relevant events implicated in this litigation took place in Germany and will involve issues of German law. Finally, the plaintiff has an alternative forum, established in part by the United States government, where she can seek redress.
Conclusion
We are sympathetic to the plaintiff and only too cognizant of the horrors suffered by her grandparents and thousands of others under the Nazi regime. Although it may not be her forum of choice, the plaintiff should pursue her claim through the Foundation, which was established by the American and German governments to ad *1241 dress exactly these types of claims from the Nazi era.
For the above reasons, we AFFIRM the decision of the district court.
Notes
. O&K exists today as a subsidiary of the Fiat Group and it continues to produce railroad, construction, and excavation equipment.
. The plaintiff does not provide a figure of what the shares would be worth today.
.The treaty provided that “[t]he Federal Republic hereby acknowledges the need for, and assumes the obligation to implement fully and expeditiously and by every means in its power, the legislation referred to in Article 1 of this Chapter [referencing the United States military law on restitution of identifiable property] and the programmes for restitution and reallocation thereunder provided.” See Termination Agreement, ch. 3, art. II. Chapter Four of the Agreement obligated the Federal Republic of Germany to provide "adequate compensation” to those persecuted by the Nazi government, but explicitly excluded "identifiable property subject to restitution.” See Termination Agreement, ch. 4, para. 1. Presumably this was because identifiable property would be subject to full, not adequate, restitution.
. The agreement was concluded by the President without ratification by either 2/3 of the Senate or a majority vote of Congress.
. The Foundation would also hear claims concerning unpaid insurance policies and slave labor, two issues which had gone largely unaddressed earlier.
. The United States filed such a statement in this case, both before the district court and before this court. The statement before the district court is included in the record excerpts. The statement before this court is included in the United States’ amicus brief. *1232 The German government has also filed a statement of interest.
. The plaintiff also brought a claim under federal law for violations of international law. However, no statute provides a private right of action for violations of international law and, thus, the plaintiff has failed to state a claim on which this court can grant relief. This court previously has recognized a private right of action for violations of international law
only
where there is a statute expressing Congress’s intention to permit private suits. In
Abebe-Jira v. Negewo,
. The district court determined that the plaintiff has not established that she has the capacity to represent the Orenstein estate. The plaintiff’s claim is derivative of the claims of her mother and grandmother, but under Florida law, she must show that she is the personal representative of the estate. This is a defect that can be cured by a stay or amendment.
See Glickstein v. Sun Bank/Miami, N.A.,
. The agreement is a treaty under international law but not a treaty under domestic law. Under international law, any agreement between states is a treaty. The same is not true under federal law. Article Two, Section 2 of the United States Constitution requires that an international agreement gain the advice and consent of two-thirds of the Senate to become a treaty. Because the President formed this agreement without the advice and consent of the Senate, the Foundation Agreement is a “sole executive agreement,” rather than a treaty, by American constitutional standards. Nonetheless, it is still federal law. The Supreme Court has held that sole executive agreements override inconsistent state law.
See United States v. Belmont,
We acknowledge that an executive agreement could preempt state law under the President’s foreign affairs power and yet include terms that may not be valid under federal law.
See Dames & Moore
v.
Regan,
At a more specific level, our cases have recognized that the President has authority to make "executive agreements" with other countries, requiring no ratification by the Senate or approval by Congress, this power having been exercised since the early years of the Republic. Making executive agreements to settle claims of American nationals against foreign governments is a particularly longstanding practice....
The executive agreements at issue here do differ in one respect from those just mentioned insofar as they address claims associated with formerly belligerent states, but against corporations, not the foreign governments. But the distinction does not matter. Historically, wartime claims against even nominally private entities have become issues in international diplomacy, and three of the postwar settlements dealing with reparations implicating private parties were made by the Executive alone.

. Article 4 declares that "Annexes A, B and C shall be an integral part of this Agreement.” Foundation Agreement, art. IV, 39 I.L.M. at 1300.
. This strategy of non-settlement distinguishes the Foundation Agreement from other claim settlement agreements previously applied by the federal courts. For instance, the Litvinov Agreement, which was the subject of the litigation in

explicitly settled all American claims against the Soviet

Turner Entm’t, 25 F.3d at 1518 ("Federal courts have a Virtually unflagging obligation' to exercise the jurisdiction conferred upon them. Nevertheless, in some private international disputes the prudent and just action for a federal court is to abstain from the exercise of jurisdiction.”)(internal citations omitted).

Altmann,
. Paragraph 11 of Annex A states:
The Foundation legislation will provide that persons who suffered loss of or damage to property during the National Socialist era as a result of racial persecution directly caused by German companies are eligible to recover under the payment system set forth in paragraph 11. The eligibility of *1240 such persons will be limited to those who could not receive any payment under the BEG or Federal Restitution Law ("BRueckG") because they did not meet the residency requirement or could not file their claims by the deadline because they lived under a government with which the Federal Republic of Germany did not have diplomatic relations, those whose claims were rejected under the BEG or BRueckG where legal proof became available only after the reunification of the Federal Republic of Germany, provided the claims were not covered by post-reunification restitution or compensation legislation, and those whose racially-motivated property claims concerning moveable property were denied or would have been denied under the BEG or BRueckG because the claimant, while able to prove a German company was responsible for seizing or confiscating property, was not able to prove that the property was transferred into then-West Germany (as required by law) or, in the case of bank accounts, that compensation was or would have been denied because the sum was no longer identifiable, where either (a) the claimant can now prove the property was transferred into then-West Germany or (b) the location of property is unknown.
