SACK, Circuit Judge:

The plaintiffs in this case filed five separate lawsuits between 2004 and 2010 in the United States District Court for the Eastern District of New York against the defendant, Arab Bank, PLC. Oran Almog, et al. v. Arab Bank, PLC, No. 04-CV-5564 (E.D.N.Y. filed Dec. 21, 2004)2; Gila Afriat-Kurtzer, et al. v. Arab Bank, PLC, No. 05-CV-0388 (E.D.N.Y. filed Jan. 21, 2005)3; Joseph Jesner, et al. v. Arab Bank, PLC, No. 06-CV-3869 (E.D.N.Y. filed Aug. 9, 2006); Yaffa Lev, et al. v. Arab Bank, PLC, No. 08-CV3251, 2008 WL 5354204 (E.D.N.Y. filed Aug. 11, 2008); Viktoria Agurenko, et al. v. Arab Bank, PLC, No. 10-CV0626 (E.D.N.Y. filed Feb. 11, 2010).

The plaintiffs are aliens who were injured or captured by terrorists overseas, or family members and estate representatives of those who were injured, captured, or killed. The plaintiffs seek judgments against Arab Bank, PLC — a bank headquartered in Jordan with branches in various places around the world — for allegedly financing and facilitating the activities of organizations that committed the attacks that caused the plaintiffs' injuries. It is undisputed that, as a PLC,4 Arab Bank is a corporation for purposes of this appeal.

The plaintiffs allege violations by Arab Bank of the Anti-Terrorism Act (the "ATA"), 18 U.S.C. § 2333(a) (providing that "[a]ny national of the United States injured in his or her person, property, or business by reason of an act of international terrorism, or his or her estate, survivors, or heirs, may sue therefor in any appropriate district court of the United States"), the Alien Tort Statute, 28 U.S.C. § 1350 (the "ATS")5 (providing that "[t]he district courts shall have original jurisdiction of any civil action by an alien for a tort only, committed in violation of the law of nations or a treaty of the United States"), and federal common law.6 The ATS differs from the ATA in that, among other things, it provides jurisdiction only with respect to suits by "aliens," while the ATA provides jurisdiction only for suits by "national[s] of the United States."7

Between 2007 and 2010, the plaintiffs' federal common-law claims were dismissed as redundant and lacking what the district court called a "sound basis."8 On May 24, 2013, the defendant also moved to dismiss the plaintiffs' ATS claims, arguing that the law of this Circuit prohibits ATS suits against corporate entities. In their briefing in the district court, the plaintiffs responded to the defendant's arguments on their merits but also argued, in the alternative, that if the district court granted the defendant's motion, it should also reinstate the plaintiffs' federal common-law claims or permit the plaintiffs to plead related non-federal common-law claims.

On August 23, 2013, the district court issued the following order:

Jesner v. Arab Bank, 06-CV-3869, Unnumbered Dkt. Entry on Aug. 23, 2013. Soon thereafter, judgments on the pleadings were entered in each of the individual cases as to the ATS claims. The plaintiffs filed timely appeals as to these claims.9

On appeal, the plaintiffs argue principally that this Circuit's opinion in Kiobel v. Royal Dutch Petroleum Co., 621 F.3d 111 (2d Cir.2010) ("Kiobel I"), aff'd on other grounds, Kiobel v. Royal Dutch Petroleum Co., ___ U.S. ___, 133 S.Ct. 1659, 185 L.Ed.2d 671 (2013) ("Kiobel II"), when analyzed in light of the Supreme Court's decision in Kiobel II, is no longer "good law," or at least, does not control this case. The plaintiffs also contend that the facts alleged sufficiently touch and concern the territory of the United States as required under Kiobel II to support jurisdiction, although they request that we remand to the district court for an initial decision on this issue. Finally, and in the alternative, the plaintiffs request the opportunity either to reinstate their federal common-law claims or to amend their pleadings in order to plead non-federal common-law claims.

BACKGROUND

I. The Plaintiffs' Claims

The plaintiffs in the underlying cases are U.S. and foreign nationals who have brought suit against Arab Bank for its alleged role in facilitating terrorist operations that harmed the plaintiffs. While the underlying cases contain differing factual allegations, they are, as the plaintiffs assert, "based on the same nucleus of [purported] material facts." Appellants' Br. at 1 n. 1. In recounting those facts to this Court, the plaintiffs' briefing relies heavily on the operative, amended complaint in Zur v. Arab Bank, PLC. In providing a summary of the facts of this case, we therefore draw, at times verbatim, from the district court's thorough opinion addressing a previous motion to dismiss by Arab Bank in Zur (sub nom. Almog v. Arab Bank, PLC, 471 F.Supp.2d 257 (E.D.N.Y.2007)).10

According to the plaintiffs, over the past two decades, four prominent Palestinian terrorist organizations — the Islamic Resistance Movement ("HAMAS"), the Palestinian Islamic Jihad ("PIJ"), the Al Aqsa Martyrs' Brigade ("AAMB"), and the Popular Front for the Liberation of Palestine ("PFLP") (collectively "the terrorist organizations")11 — have conducted widespread murderous attacks, including suicide bombings, against citizens of Israel — mostly Jews. The terrorist organizations allegedly arranged those attacks in part by promising, and later delivering, financial payments to the relatives of "martyrs" who were killed — along with those who were injured or captured — while perpetrating the attacks. See Almog, 471 F.Supp.2d at 260-61.

The plaintiffs assert that the terrorist organizations funded these attacks in two ways. The organizations solicited public and private donations directly and deposited them in bank accounts throughout the Middle East. The organizations also raised funds through affiliated, purportedly charitable proxy organizations, including two entities created in Saudi Arabia: the Popular Committee for Assisting the Palestinian Mujahideen and the Saudi Committee for Aid to the Al-Quds Intifada (the "Saudi Committee"). These two organizations allegedly set up their own bank accounts, under the shared label "Account 98," at various banks in Saudi Arabia in order to hold funds collected for the families of "martyrs." See id. at 261-62.

According to the amended complaint, Arab Bank — one of the largest financial institutions in the Middle East, with branches and subsidiaries in more than twenty-five countries, including a New York branch that provides clearing and correspondent banking services to foreign financial institutions — deliberately helped the terrorist organizations and their proxies to raise funds for attacks and make payments to the families of "martyrs." The plaintiffs further allege that Arab Bank used some of those facilities — the New York branch among them — to support the terrorist organizations in three ways. See id. at 261-62.

First, Arab Bank allegedly maintained accounts that the terrorist organizations used to solicit funds directly. The plaintiffs allege, with respect to HAMAS specifically, that Arab Bank "collected" funds into HAMAS accounts in its Beirut, Lebanon, and Gaza Strip branches. Supporters knew to donate to HAMAS directly through Arab Bank because the HAMAS website directed supporters to make contributions to Arab Bank's Gaza Strip branch, and because there were various advertisements publicized throughout the Middle East calling for donations to Arab Bank accounts. According to the plaintiffs, Arab Bank knew that the donations were being collected for terrorist attacks. See id. at 262.

Second, Arab Bank allegedly maintained accounts that proxy organizations and individuals used to raise funds for the terrorist organizations. For example, according to the amended complaint, Arab Bank maintained accounts, solicited and collected donations, and laundered funds for some of the purported charitable organizations that acted as fronts for the terrorist organizations. Arab Bank also maintained accounts for individual supporters of terrorist organizations such as HAMAS and al Qaeda. Again, responsible officials at Arab Bank purportedly knew that the accounts of these various organizations and individuals were being used to fund the suicide bombings and other attacks sponsored by the terrorist organizations. See id.

Third, Arab Bank allegedly played an active role in identifying the families of "martyrs" and facilitating payments to them from the Saudi Committee's "Account 98" funds, on behalf of the terrorist organizations. According to the plaintiffs, Arab Bank first worked with the Saudi Committee and HAMAS to finalize lists of eligible beneficiaries. Arab Bank then created individual bank accounts for the beneficiaries and facilitated transfers of "Account 98" funds into those accounts, often routing the transfers through its New York branch in order to convert Saudi currency into Israeli currency. Once the accounts were filled, Arab Bank provided instructions to the public on how to qualify for and collect the money, and made payments to beneficiaries with appropriate documentation. See id. at 262-63.

The plaintiffs allege that Arab Bank's involvement with the terrorist organizations — particularly its facilitation of payments to the families of "martyrs" — incentivized and encouraged suicide bombings and other murderous acts that harmed the plaintiffs. See id. at 263.

II. Procedural History

The plaintiffs in the consolidated cases filed five separate lawsuits between 2004 and 2010 in the United States District Court for the Eastern District of New York against Arab Bank alleging variations on the theme of the foregoing facts. See Almog, 04-CV-5564 (E.D.N.Y. filed Dec. 21, 2004); Afriat-Kurtzer, 05-CV-0388 (E.D.N.Y. filed Jan. 21, 2005); Jesner, 06-CV-3869 (E.D.N.Y. filed Aug. 9, 2006); Lev, 08-CV-3251 (E.D.N.Y. filed Aug. 11, 2008); Agurenko, PLC, 10-CV-0626 (E.D.N.Y. filed Feb. 11, 2010). All five lawsuits included tort claims under the ATS. At the district court level, these cases were consolidated, along with six others, for discovery and pre-trial proceedings.12

On August 23, 2013, the district court dismissed the plaintiffs' ATS claims on the basis of Kiobel I. Jesner v. Arab Bank, 06-CV-3869, Unnumbered Dkt. Entry on Aug. 23, 2013. At the time, ATS claims were the only ones remaining in three of the five cases before the district court: Jesner, Lev, and Agurenko. Final judgments were therefore filed in each of those cases on August 28, 2013. The two remaining actions, Almog and Afriat-Kurtzer, involved both ATS claims and ATA claims, the latter of which remained intact after the district court's August 23, 2013 order. As a result, partial final judgments as to the ATS claims were issued in those cases on October 16, 2013.

The plaintiffs in all five cases appealed to this Court from the judgments on the pleadings regarding their ATS claims. On December 10, 2013, the plaintiffs collectively moved to consolidate the appeals. We granted that motion on January 6, 2014.

For the following reasons, we affirm the judgments of the district court.

DISCUSSION

I. Standard of Review

"We review de novo a district court's decision to grant a motion for judgment on the pleadings pursuant to Federal Rule of Civil Procedure 12(c)." Hayden v. Paterson, 594 F.3d 150, 160 (2d Cir.2010). In doing so, we "employ[ ] the same ... standard applicable to dismissals pursuant to [Federal Rule of Civil Procedure] 12(b)(6)." Johnson v. Rowley, 569 F.3d 40, 43 (2d Cir.2009) (quotation marks omitted). Thus, we "accept[ ] as true factual allegations made in the complaint, and draw[ ] all reasonable inferences in favor of the plaintiffs." Town of Babylon v. Fed. Hous. Fin. Agency, 699 F.3d 221, 227 (2d Cir.2012). "To survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to `state a claim to relief that is plausible on its face.'" Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007)).

II. Corporate Liability Under the Alien Tort Statute

We conclude that Kiobel I is and remains the law of this Circuit, notwithstanding the Supreme Court's decision in Kiobel II affirming this Court's judgment on other grounds. We affirm the decision of the district court on that basis. We do so despite our view that Kiobel II suggests that the ATS may allow for corporate liability and our observation that there is a growing consensus among our sister circuits to that effect. Indeed, on the issue of corporate liability under the ATS, Kiobel I now appears to swim alone against the tide.

A. The Decisions in Kiobel I and Kiobel II

To repeat: The ATS provides, in full, that "[t]he district courts shall have original jurisdiction of any civil action by an alien for a tort only, committed in violation of the law of nations or a treaty of the United States." 28 U.S.C. § 1350. In Kiobel I, the panel divided over the breadth of liability recognized by the "law of nations"—and, consequently, on whether corporations may be held liable under the ATS.

The majority opinion, written by Judge Cabranes and joined by then-Chief Judge Jacobs, concluded that the ATS does not permit claims against corporations because "[n]o corporation has ever been subject to any form of liability (whether civil, criminal, or otherwise) under the customary international law of human rights." 621 F.3d at 148 (emphasis in original). This conclusion was based on the majority's view that the law of nations must affirmatively extend liability to "a particular class of defendant, such as corporations," before that class of defendant may be held liable for conduct that violates a substantive norm of customary international law. Id. at 127. As precedential support for that view, the majority cited footnote 20 in Sosa v. Alvarez-Machain, 542 U.S. 692, 124 S.Ct. 2739, 159 L.Ed.2d 718 (2004). In Sosa, commenting on the portion of the opinion that instructed "federal courts ... not [to] recognize private claims under federal common law for violations of any international law norm with less definite content and acceptance among civilized nations than the historical paradigms familiar when § 1350 was enacted," id. at 732, 124 S.Ct. 2739, the Supreme Court stated that "[a] related consideration is whether international law extends the scope of liability for a violation of a given norm to the perpetrator being sued, if the defendant is a private actor such as a corporation or individual," id. at 732 n. 20, 124 S.Ct. 2739.

Judge Leval, Kiobel I's third panel member, filed an opinion concurring in the judgment for the defendant, but sharply contesting the majority's conception of liability under the law of nations. He described "[i]nternational law, at least as it pertains to human rights," as "a sparse body of norms ... prohibiting conduct," which lacks comprehensive rules regarding liability and so "leaves the manner of enforcement... almost entirely to individual nations." 621 F.3d at 152 (Leval, J., concurring). Judge Leval argued that Sosa's footnote 20 is consistent with that view inasmuch as it does no more than caution courts to defer to the law of nations on the scope of liability in those exceptional cases where customary international law affirmatively bars recovery against private actors:

Id. at 165 (quotation marks and emphases omitted). Under that view, the ATS does not prohibit corporate liability per se. Instead, if unspecified by the international law in question, the scope of liability under the ATS is appropriately classified as a question of remedy to be settled under domestic law. See id. at 152.

The plaintiffs in Kiobel I obtained a writ of certiorari from the United States Supreme Court. In its eventual opinion on the merits, the Supreme Court described the case's rather arduous path to and before it:

Kiobel II, 133 S.Ct. at 1663 (citations omitted in part).13

Thus, the Supreme Court first agreed to review the judgment of this Court. After being supplied with briefing and conducting oral argument directed to the analysis we had employed in Kiobel I, the Court decided to address a different issue. The Court concluded not that Kiobel I was right on the law, but that it was right in its conclusion because of the presumption against extraterritoriality. The Court observed that "all the relevant conduct took place outside the United States," which justified dismissal of the plaintiffs' ATS claims. Id. at 1669.

B. The Impact of Kiobel II on Kiobel I

Although the route the Supreme Court took to its decision in Kiobel II seems to suggest that the Court was less than satisfied with our approach to jurisdiction over the cases on appeal under the ATS, it neither said as much nor purported to overrule Kiobel I. The two decisions adopted different bases for dismissal for lack of subject-matter jurisdiction. Whatever the tension between them, the decisions are not logically inconsistent.

The Supreme Court chose to affirm Kiobel I on extraterritoriality grounds without reaching the corporate liability question. Id. at 1663. But because both of these questions concern the proper interpretation of the ATS itself, and because the ATS is strictly jurisdictional,14 it follows that both of these questions are jurisdictional. Regarding corporate liability, Kiobel I held that federal courts lack jurisdiction over ATS suits against corporations; as to extraterritoriality, Kiobel II held that federal courts lack jurisdiction over ATS suits based solely on extraterritorial conduct unless that conduct sufficiently touches and concerns the territory of the United States.15 Taken together, they require that if either the defendant in an ATS suit is a corporation, or the ATS suit is premised on conduct outside the United States that does not sufficiently touch and concern the territory of the United States, or both, the federal court in which the suit was brought lacks jurisdiction.16

Generally speaking, "this panel is bound by prior decisions of this court unless and until the precedents established therein are reversed en banc or by the Supreme Court." United States v. Jass, 569 F.3d 47, 58 (2d Cir.2009); see also, e.g., Jones v. Coughlin, 45 F.3d 677, 679 (2d Cir.1995) (similar). We have recognized, though, that there is an exception to this general rule when an "intervening Supreme Court decision ... casts doubt on our controlling precedent." Wojchowski v. Daines, 498 F.3d 99, 106 (2d Cir.2007) (quotation marks omitted).17 "[F]or this exception to apply, the intervening decision need not address the precise issue already decided by our Court." Union of Needletrades, Indus. & Textile Empls., AFL-CIO, CLC v. U.S. I.N.S., 336 F.3d 200, 210 (2d Cir.2003). Instead, there must be a conflict, incompatibility, or "inconsisten[cy]" between this Circuit's precedent and the intervening Supreme Court decision. Wojchowski, 498 F.3d at 109. The effect of intervening precedent may be "subtle," but if the impact is nonetheless "fundamental," it requires this Court to conclude that a decision of a panel of this Court is "no longer good law." Id. (quotation marks and alteration omitted).

Kiobel II does cast a shadow on Kiobel I in several ways.18

First, in Kiobel II, the Supreme Court stated that "[c]orporations are often present in many countries, and it would reach too far to say that mere corporate presence suffices" to displace the presumption against extraterritorial application. 133 S.Ct. at 1669. The implication of a statement that mere corporate presence is insufficient would seem to be that corporate presence may, in combination with some other factual allegations, be sufficient—so jurisdiction over ATS suits against corporations is sometimes proper. Indeed, if corporate liability under the ATS were not possible as a general matter, the Supreme Court's statement about "mere corporate presence" would seem meaningless. Accordingly, Kiobel II appears to suggest that the ATS allows for some degree of corporate liability.

Second, Kiobel II embraced an interpretation of Sosa that seems to us to be more consistent with Judge Leval's Kiobel I concurrence than the majority opinion. According to the Supreme Court, "[t]he question under Sosa" is "whether [a federal] court has authority to recognize a cause of action under U.S. law to enforce a norm of international law." Kiobel II, 133 S.Ct. at 1666 (emphasis added). The Supreme Court further stated that the ATS empowers federal courts to recognize such a cause of action "under federal common law" to enable litigants to bring "private claims" based on "international law violations." Id. at 1663 (quoting Sosa, 542 U.S. at 724, 732, 124 S.Ct. 2739). Kiobel II thus appears to reinforce Judge Leval's reading of Sosa, which derives from international law only the conduct proscribed, leaving domestic law to govern the available remedy and, presumably, the nature of the party against whom it may be obtained.19 If that is so, Kiobel II suggests that Kiobel I relies in part on a misreading of Sosa.20

Third, Kiobel I and Kiobel II may work in tandem to narrow federal courts' jurisdiction under the ATS more than what we understand Congress may have intended in passing the statute. As Justice Breyer noted in his Kiobel II concurrence, the basic purpose of the ATS is to provide compensation to foreign plaintiffs injured by "pirates," "torturers," "perpetrators of genocide," and similar actors. Kiobel II, 133 S.Ct. at 1672-75 (Breyer, J., concurring in the judgment). Together, Kiobel I and Kiobel II put such aggrieved potential plaintiffs in a very small box: The two decisions read cumulatively provide that plaintiffs can bring ATS suits against only natural persons, and perhaps non-corporate entities, based on conduct that occurs at least in part within (or otherwise sufficiently touches and concerns) the territory of the United States. At a time when large corporations are often among the more important actors on the world stage,21 and where actions and their effects frequently cross international frontiers, Kiobel I and Kiobel II may work together to prevent foreign plaintiffs from having their day in court in a far greater proportion of tort cases than Congress envisioned when, centuries ago, it passed the ATS.

Our reading of Kiobel II is bolstered by what appears to be a growing consensus among our sister circuits that the ATS allows for corporate liability. To date, the other circuits to have considered the issue have all determined that corporate liability is possible under the ATS. See Doe I v. Nestle USA, Inc., 766 F.3d 1013, 1022 (9th Cir.2014); Doe VIII v. Exxon Mobil Corp., 654 F.3d 11, 57 (D.C.Cir.2011), vacated on other grounds, 527 Fed.Appx. 7 (D.C.Cir. 2013); Flomo v. Firestone Nat. Rubber Co., 643 F.3d 1013, 1021 (7th Cir.2011); Romero v. Drummond Co., 552 F.3d 1303, 1315 (11th Cir.2008); see also Al Shimari v. CACI Premier Tech., Inc., 758 F.3d 516, 530-31 (4th Cir.2014) (holding that the district court erred in concluding that it lacked subject matter jurisdiction over an ATS claim against a corporate defendant on extraterritoriality grounds, and finding that the plaintiffs' ATS claims sufficiently "`touch[ed] and concern[ed]' the territory of the United States" based on, inter alia, the corporate defendant's "status as a United States corporation"); Beanal v. Freeport-McMoran, Inc., 197 F.3d 161, 163 (5th Cir.1999) (dismissing ATS claims against corporate defendants under Rule 12(b)(6), and to that extent appearing to implicitly assume jurisdiction over ATS claims against corporate defendants).

For those reasons, Kiobel II may be viewed as an "intervening Supreme Court decision that casts doubt on [Kiobel I]," Wojchowski, 498 F.3d at 106 (quotation marks omitted), even though it does not "address the precise issue" of corporate liability, Union of Needletrades, 336 F.3d at 210. Kiobel II suggests a reading of the ATS that is at best "inconsistent" with Kiobel I's core holding, which along with the views of our sister circuits indicates that something may be wrong with Kiobel I.

We nonetheless decline to conclude that Kiobel II overruled Kiobel I. We think that one panel's overruling of the holding of a case decided by a previous panel is perilous. It tends, in our view, to degrade the expectation of litigants, who routinely rely on the authoritative stature of the Court's panel opinions. It also diminishes respect for the authority of three-judge panel decisions and opinions by which the overwhelming majority of our work, and that of other circuits, is accomplished. See 13 Charles Alan Wright & Arthur R. Miller et al., Federal Practice and Procedure § 3506 (3d ed. 1998) (noting that "[t]he courts of appeals generally follow the practice that one panel is bound by the previous decision of another panel of that court," and collecting cases).22 We will leave it to either an en banc sitting of this Court or an eventual Supreme Court review to overrule Kiobel I if, indeed, it is no longer viable. Cf. Ark. Carpenters Health & Welfare Fund v. Bayer AG, 604 F.3d 98, 108-10 (2d Cir.2010) (applying a prior panel's decision while explicitly disagreeing with it and proffering "several reasons why this case might be appropriate for reexamination by our full Court").23

If this Court declines to overrule Kiobel I (either on the merits or by refusing to proceed en banc), the Supreme Court would, of course, be able to do so should it choose to hear the case. The Supreme Court granted certiorari on this issue in 2011 when it first decided to hear an appeal from Kiobel I. Kiobel v. Royal Dutch Petroleum Co., ___ U.S. ___, 132 S.Ct. 472, 181 L.Ed.2d 292 (2011). Having nonetheless avoided addressing the issue directly in Kiobel II, perhaps it would decide to grant certiorari on this issue again—especially in light of the divergence of federal case law since.

Finally, the district court dismissed the plaintiffs' ATS claims solely on corporate liability grounds under Kiobel I. It is well settled that "we may affirm on any grounds for which there is a record sufficient to permit conclusions of law, including grounds not relied upon by the district court." Olsen v. Pratt & Whitney Aircraft Div. of United Techs. Corp., 136 F.3d 273, 275 (2d Cir.1998) (quoting Chesley v. Union Carbide Corp., 927 F.2d 60, 68 (2d Cir.1991)); see also N.Y. State Elec. & Gas Corp. v. FirstEnergy Corp., 766 F.3d 212, 222 n. 4 (2d Cir.2014) (same, citing Olsen). However, we have discretion to choose not to do so based on prudential factors and concerns. See Bacolitsas v. 86th & 3rd Owner, LLC, 702 F.3d 673, 681 (2d Cir. 2012) ("While generally we decline considering arguments not addressed by the district court, this is a prudential rule we apply at our discretion. In determining whether to consider such issues, we rely on a number of factors, including the interests of judicial economy, and whether the unaddressed issues present pure questions of law." (citations omitted)).

It is tempting to seek to avoid grappling with issues requiring an analysis of the relationship between Kiobel I and Kiobel II and the continuing viability of Kiobel I simply by affirming the district court's judgments on the basis of Kiobel II alone. We nevertheless decline to do so for several reasons. First, inasmuch as the district court did decide the case based solely on a mechanical application of Kiobel I, if it is "good law," an affirmance on the basis of Kiobel I is the simplest, most direct route to that result. By contrast, in order to affirm on the grounds that law established by Kiobel II prohibits the assumption of jurisdiction in this case, we would have to decide in the first instance that the alleged activities underlying the plaintiffs' claims do not touch and concern the United States sufficiently to justify a conclusion that the district court had subject matter jurisdiction under Kiobel II's extraterritoriality test. It seems to us to be unwise to decide the difficult and sensitive issue of whether the clearing of foreign dollar-denominated payments through a branch in New York could, under these circumstances, displace the presumption against the extraterritorial application of the ATS, when it was not the focus of either the district court's decision or the briefing on appeal. See, e.g., Amicus Curiae Brief of the Institute of International Bankers at 5-20 (discussing several concerns regarding whether the clearing of foreign dollar-denominated transfers through the United States would be sufficient domestic conduct to allow suit under the ATS).

Moreover, deciding this appeal solely on the basis of Kiobel I may well further the development of the law of this Circuit in this regard. If Kiobel I remains authoritative, litigants would benefit from the settling of expectations that clarification would bring. And if the rule of Kiobel I does not prevail, then leaving it unnecessarily "on the books" is worrisome—it may result in the dismissal of cases that are meritorious, including possibly multidistrict litigations that are randomly assigned to the district courts in this Circuit. Perhaps more insidiously, plaintiffs with ATS claims against corporations that turn out to be permissible might well be dissuaded from asserting them in this Circuit despite their ultimate merit.

We therefore affirm on the basis of the holding of Kiobel I.

III. Common Law Claims

The plaintiffs request that if we affirm the dismissal of their ATS claims—as indeed we do—we reinstate the "general federal common law" claims asserted in their complaints (to which they refer on appeal as their "general common-law tort" claims), which the district court dismissed as redundant and lacking a "sound basis." Almog, 471 F.Supp.2d at 294. Alternatively, the plaintiffs request leave to amend their complaints in order to re-plead under state or foreign law the claims that they originally pleaded under federal common law. We decline both requests.

First, we will not reinstate the plaintiffs' federal24 common-law causes of action because we discern no basis for such nebulous, non-statutory claims under federal law.25 See Republic of Iraq v. ABB AG, 768 F.3d 145, 172 (2d Cir.2014) (concluding that if a plaintiff's "assertion of nonstatutory wrongs describes traditional types of torts by private entities," the plaintiff's claims arise "under state law rather than federal common law," unless the plaintiff can identify a "uniquely federal interest in the rules of decision to be applied," or a "conflict between a federal policy or interest and the use of state law").

As for leave to amend the complaints, "we review [the district court's refusal to allow such amendment] only for abuse of discretion which ordinarily we will not identify absent an error of law, a clearly erroneous assessment of the facts, or a decision outside the available range of permitted choices." Knife Rights, Inc. v. Vance, 802 F.3d 377, 389 (2d Cir.2015) (citations omitted). While "[l]eave to amend should be freely granted, ... the district court has the discretion to deny leave if there [was] a good reason for it, such as futility, bad faith, undue delay, or undue prejudice to the opposing party." Jin v. Metro. Life Ins. Co., 310 F.3d 84, 101 (2d Cir.2002).

The plaintiffs have spent more than ten years litigating the matters before us but have not specified any particular state or foreign common-law theory on which they seek to recover. To be sure, they have in their complaints and in their briefing on appeal asserted that they may recover under general principles of joint-venture liability, agency, reckless disregard, intentional injury of others by a third party, reckless disregard, wrongful death, survival, and negligent or intentional infliction of emotional distress. But their short and conclusory statements to this effect, untethered to the law of any particular jurisdiction or any serious attempt at explanation, did not put the defendant on notice of specific state or foreign common-law claims that it might be called upon to defend against in this litigation.26 The plaintiffs have had ample time to develop and assert such theories. The district court did not abuse its discretion in denying leave to amend because permitting the plaintiffs to repackage their federal common-law claims as state or foreign common-law claims at such a late stage would, we think, do a disservice both to the courts in which they chose to litigate their claims, and to the defendant, which must prepare itself to defend against them.

Permitting the plaintiffs in Jesner, Lev, and Agurenko to amend their complaints would, moreover, have been futile. Following the dismissal of the plaintiffs' ATS claims, the only basis on which the district court might exercise jurisdiction over these actions would be diversity of citizenship. But "diversity is lacking ... where the only parties are foreign entities, or where on one side there are citizens and aliens and on the opposite side there are only aliens." Universal Licensing Corp. v. Paola del Lungo S.p.A., 293 F.3d 579, 581 (2d Cir.2002). Here, there are aliens on both sides of the litigation—plaintiffs are aliens (only aliens can bring ATS claims), and so is the defendant, a citizen of Jordan—and the Jesner, Lev, and Agurenko plaintiffs do not seek to assert any other federal claims that might provide a basis for federal-question jurisdiction. For these reasons, permitting the Jesner, Lev, and Agurenko plaintiffs to amend their complaints to assert non-federal common-law claims would be fruitless.

The district court therefore acted within its discretion in declining to permit the plaintiffs to amend their complaints.

CONCLUSION

For the foregoing reasons, we AFFIRM the judgments of the district court.
