(1) Whether, when evaluating if property of a foreign sovereign is immune from execution under the Foreign Sovereign Immunities Act, courts should apply state law or a uniform federal standard to determine the location of the property; (2) whether property of a foreign sovereign was "used for commercial activity in the United States" as contemplated by the act if the property is only connected to a broader transaction that includes U.S. components; and (3) whether property of a foreign sovereign is subject to execution under the act if the only commercial use in the United States is aberrational or hypothetical.
