Iceland is a member of the North Atlantic Treaty Organization (NATO) but has no standing military of its own. In 2006, the U.S. announced it would continue to provide for Iceland's defense but without permanently basing forces in the country.
Iceland has no military, but the country's coast guard fulfills most military missions, and is responsible for maintaining Keflavik as a military installation. The last U.S. forces left Iceland in 2006. U.S. aircraft occasionally still use the base's facilities.
