Whether the district court must abstain from exercising jurisdiction under the Foreign Sovereign Immunities Act for reasons of international comity where plaintiffs did not exhaust local remedies

QUESTIONS PRESENTED 1. May the district court abstain from exercising jurisdiction under the Foreign Sovereign Immunities Act for reasons of international comity, where former Hungarian nationals have sued the nation of Hungary to recover the value of property lost in Hungary during World War II, and where the plaintiffs made no attempt to exhaust local Hungarian remedies? 2. In a forum non conveniens analysis, (a) is the district court required to defer to plaintiffs’ choice of a U.S. forum where the case’s sole connection to the United States is that some named _ plaintiffs (representing a putative worldwide class) became naturalized citizens after the time relevant to the complaint; and (b) is the district court permitted to defer to a foreign sovereign defendant’s comity interest in hosting claims in its own courts, where plaintiffs allege the sovereign defendant harmed its own nationals on its own soil and plaintiffs have not exhausted local remedies?
