Indonesia (1965–1966): The Anti-Communist Purges
Historical Context & Mechanics
Following a failed coup attempt on September 30, 1965, General Suharto established military control over Indonesia, launching a systematic campaign to eradicate the Indonesian Communist Party (PKI), then the third-largest communist party in the world.
The Documented Atrocities
Between 500,000 and one million civilians—including suspected PKI members, trade unionists, ethnic Chinese, and peasant organizers—were extrajudicially executed, tortured, or imprisoned in labor camps by the Indonesian armed forces and civilian paramilitary units.
The U.S. Embassy in Jakarta, under Ambassador Marshall Green, routinely compiled lists of thousands of suspected PKI leaders and passed them directly to the Indonesian military. A cable dated October 1965 shows officials expressing explicit approval as the military hunted down suspected leftists. U.S. agencies provided covert communications equipment, small arms, and financial support to the military leadership as the purges were actively underway.
