When the Kennedy administration encountered the nine-year old Bolivian Revolution in 1961, there appeared a very real possibility that La Paz was headed toward the Soviet camp. By incorporating Bolivian fully within the new administration's development program known as the Alliance for Progress, Kennedy officials halted Bolivia's leftward drift and secured it within the US sphere of influence. This paper follows Kennedy officials' initial reaction to Bolivia in January 1961 through to its adoption of an aggressively interventionist policy of military-led development. Seizing on Bolivian leaders' interest in rapid modernization, Washington employed seemingly apolitical developmental theories for political, even imperial, ends. While failing at “development,” the Kennedy administration's militarized developmental intervention succeeded at de-Communizing the Bolivian Revolution and reversing its neutralist pretentions.
