According to Wikipedia, the loophole has since been closed: > The ambiguity was later resolved (at least for the United States) by an amendment to the Federal Criminal Code, which added a provision establishing federal jurisdiction when "...the offense is committed by or against a national of the United States at a place outside the jurisdiction of any nation", intended in part to address these issues.[6] It became law as 18 U.S.C. § 7(7) in 1984.[7] Of course, things will get interesting when the offense is committed against the national of another country with the same claim, meaning they would both have jurisdiction.
