foreign states and their instrumentalities. Halkbank argues that those state prosecutions would raise foreign policy concerns. But we must interpret the FSIA as written. And the statute simply does not grant immunity to foreign states and their instrumentalities in criminal matters.
In addition, it is not evident that the premise of Halkbank’s consequentialist argument is correct. To begin with, Halkbank offers no history of state prosecutors subjecting foreign states or their instrumentalities to criminal jurisdiction. And if such a state prosecution were brought, the United States could file a suggestion of immunity. A decision by a state court to deny foreign sovereign immunity might be reviewable by this Court (a question we do not here address). Moreover, state criminal proceedings involving foreign states or their instrumentalities might be preempted under principles of foreign affairs preemption (another question we do not here address). Cf. American Ins. Assn. v. Garamendi, 539 U. S. 396 (2003). And if those principles do not apply or do not suffice to protect U. S. national security and foreign policy interests, Congress and the President may always respond by enacting additional legislation.
In short, Halkbank’s various FSIA arguments are infused with the notion that U. S. criminal proceedings against instrumentalities of foreign states would negatively affect U. S. national security and foreign policy. But it is not our role to rewrite the FSIA based on purported policy concerns that Congress and the President have not seen fit to recognize. The FSIA does not provide foreign states and their instrumentalities with immunity from criminal proceedings.

Although the FSIA does not immunize Halkbank from criminal prosecution, Halkbank advances one other plea for
