For the first time, reading Melvin, Robinson, and Zhou together, the puzzle pieces of who was really behind the 30 September Movement and why its failure led to the murderous extermination of the left nearly fall into place. “Nearly” must be stressed since critical clues are still missing: most importantly from Indonesia, but also from the still-classified records of the CIA and the Defense Department in the US and of Britain’s MI6, and, crucially, from other documents from Chinese sources. But by early 1965, these studies reveal, both the army and the leaders of the PKI yearned to seize power, using President Sukarno as cover in their bid to destroy each other.
They also add to our understanding of how Indonesia, by 1965, was in the path of a cold war collision, with the US and Britain on one side and China on the other. Sukarno, who claimed to be the voice of his people and to reconcile Islam, nationalism, and socialism, marched ever leftward, decrying the “imperialist and neo-colonialist West” while embracing the PKI and the Chinese Communists. By this time, the PKI was the third-largest Communist Party in the world, after China’s and the Soviet Union’s, claiming 3.5 million members and some 20 million sympathizers, mostly peasants and workers.
Robinson captures the high stakes: by 1965 the Vietnam War was raging; after the Sino-Soviet split China was determined to recast itself as the leader of revolution in Asia, and ensuring that Sukarno and the PKI looked to China for support and inspiration mattered to Mao. With China encouraging him, Sukarno had already launched the “Crush Malaysia” campaign, calling for an armed confrontation with the neocolonialists for creating Malaysia, which he called a puppet state meant to encircle Indonesia. Alarmed, President Johnson’s national security adviser McGeorge Bundy approved more intensive covert programs.
The extent of the programs remains unknown, but Robinson has pieced together the documents that have been declassified, which describe support for the Indonesian army and Muslim groups, and psychological operations designed to provoke the PKI into doing something—ideally attempting a coup—that would provide a pretext for the army to smash it and seize power.2 The British created a division for covert political warfare against Indonesia in Singapore. By mid-August, Bundy called for a meeting “to alert the President to the seriousness of the situation in which the Communists may take over Indonesia,” a development that Undersecretary of State George Ball said “would be the biggest thing since the fall of China.”
