State Sponsors of Terrorism do not typically maintain significant assets in the United States. Therefore, the main option for judgment holders against Iran, Syria and Sudan is to attempt to enforce their FSIA judgments in countries where these governments do maintain significant assets. Unfortunately, these efforts are often unsuccessful. For example, in October 2015, the Italian Court of Cassation refused to enforce an FSIA judgment against Iran. The Italian court held that although acts of terrorism are not entitled to immunity, to be recognized, a foreign judgment must accord with Italian jurisdictional principles.
