Congress has established a strong domestic legislative foundation for combating terrorism overseas and has laid the groundwork for coordination with U.S. allies. Recent legislation to combat aspects of international terrorism includes the Foreign Airport Security Act of 1985, the International Maritime and Port Security Act of 1986, and the Omnibus Diplomatic Security and Antiterrorism Act of 1986. Multilateral mechanisms include antiterrorism assistance and training to improve airport and port security, rewards for information leading to the arrest and conviction of international terrorists, improved passport and visa controls, an international convention making international terrorism a crime, and enhanced enforcement of the Vienna Convention regarding the sanctity of diplomats and diplomatic missions. 83 footnotes.
