From 1961 to 1975, the US Central Intelligence Agency (CIA) coordinated a proxy war in Laos as a part of America’s larger effort to prevent communism from overrunning all of Southeast Asia. Codenamed “Operation Momentum”, the largely clandestine effort involved arming, training, and providing military assistance to anti-communist forces in Laos led by Hmong tribesmen and their military chief Vang Pao.

As Joshua Kurlantzick points out in his new book A Great Place to Have a War, the effort in Laos, like America’s larger effort in Vietnam, ultimately failed, resulting in Communists taking power in South Vietnam, Laos, and Cambodia, while arguably transforming the primary role of the CIA from intelligence gathering to paramilitary operations.
