CANBERRA -- The presence of insurgent or terrorist sanctuaries in nonbelligerent countries is one of the most intractable, explosive issues in international relations. It was a central fact of the Vietnam War, brought about the destruction of Lebanon, and continues to plague the coalition in Iraq. It is also key to the present war on terror in Southeast Asia.
Vietnam differed from Korea and Malaya, where containment and counterinsurgency prevailed, because the communists could outflank allied forces in South Vietnam by using "neutral" territory in Cambodia and Laos.
Like the PLO presence in Lebanon until 1982, this strategy plunged hapless host countries into civil war and provoked invasions by stronger powers, in turn spurring more extremist movements -- the Khmer Rouge, Hezbollah and Islamic Jihad.
