CIA activities in Indonesia

The CIA's involvement in Indonesia was extensive and controversial. In the 1950s, the CIA covertly supported regional rebellions against President Sukarno, including providing aid to the PRRI/Permesta rebels. This support included providing arms and logistical assistance. The CIA also engaged in propaganda efforts and paramilitary operations aimed at destabilizing Sukarno's government, due to his neutralist stance during the Cold War and increasing ties with communist countries. A key activity was the covert support for the Indonesian military in 1965-66 during the anti-communist purge, providing lists of suspected communists to the Indonesian army, contributing to widespread human rights abuses. The long-term impact of these actions continues to be debated.
