US B-52s struck Laotian locations to interdict North Vietnamese supply lines to South Vietnam in spite of the official end of the war in South Vietnam, as the peace accords did not extend to Laos.
From 1964 to 1973, the U.S. dropped more than 2,500,000 tons of bombs, or 260,000,000 bombs, making Laos the most heavily bombed country per capita in history. The Laotian bombing campaign ended on March 29, 1973 following the Agreement on the Restoration of Peace and Reconciliation in Laos between the central government and the Pathet Lao.
Laos, the only landlocked country in Southeast Asia, remains subject to a Communist government today and is effectively one of the most isolated countries in the world.
