The United States participated in the first Proliferation Security Initiative (PSI) live exercise (LIVEX) within the framework of the Mediterranean Initiative recently hosted by the government of Italy. This LIVEX, which took place in the Bay of Catania, included representatives from nearly 25 countries from multiple agencies including foreign affairs, defense, justice, customs, and law enforcement.

This LIVEX focused on helping participating countries build capacity to prevent and interdict illicit shipments of weapons of mass destruction, their delivery systems, and related materials. The live interdiction exercise reinforced the value of the PSI, and it enhanced interagency coordination of interdiction efforts, especially in the Mediterranean Sea, which accounts for approximately 30 percent of the world’s sea traffic.

PSI, now in its 15th year, is composed of 105 sovereign states that have made a political commitment to cooperate in stopping proliferation-related transfers, using their national legal authorities and taking actions consistent with international law.
