US Embassy Jakarta 'Kill Lists' for Indonesian Anti-Communist Purge (1965-1966)

SUMMARY

Multiple declassified files from the US Embassy in Jakarta, made public in October 2017, reveal the US government's detailed knowledge of and support for the Indonesian military's mass killings of alleged communists and their sympathizers in 1965-1966. Reports from news organizations and academic archives, citing the declassified documents, state that American officials provided money, equipment, and lists of communist officials to the Indonesian military. The purge resulted in the deaths of several hundred thousand to over a million people. While the declassified files confirm US tracking and support, the exact nature and direct impact of the 'kill lists' on the extent of the massacres remain subjects of historical inquiry and debate.

STRONGEST CASE FOR

The strongest case for the US embassy providing 'kill lists' that directly contributed to the Indonesian massacres is based on interpretations of the declassified documents. These documents, as reported by various news outlets and the National Security Archive, indicate that US officials in Jakarta actively tracked the killings and provided the Indonesian military with resources, including 'lists of communist officials.' This direct provision of names, alongside financial and logistical support, can be argued as a material contribution to the efficiency and scale of the extermination campaign, implying a level of complicity beyond mere observation.

STRONGEST CASE AGAINST

A counter-argument acknowledges US knowledge and support for the anti-communist campaign but emphasizes that the primary impetus and execution of the massacres were Indonesian. While US officials may have provided lists of alleged communists, it's argued that the Indonesian military already possessed extensive intelligence on PKI members. The lists might have served more as intelligence sharing rather than directly instigating or significantly escalating the killings. Furthermore, the chaotic nature and widespread local involvement in the massacres suggest that external 'kill lists,' while morally questionable, may not have been the sole or even primary driver of the violence, which had deep internal roots in Indonesian politics and society.
