UK Spies' Alleged Incitement of Indonesian Communist Mass Murders (1965-66)

SUMMARY

Multiple news reports allege that recently declassified UK Foreign Office documents reveal a clandestine British propaganda campaign that incited the mass murder of Indonesian communists in 1965-66. This campaign is claimed to have played a crucial role in the anti-communist purges orchestrated by the Indonesian army, which resulted in the deaths of hundreds of thousands to over a million people. The CIA reportedly described these events as one of the worst mass murders of the century.

The core of the claims centers on British propagandists secretly urging anti-communists, including army generals, to 'eliminate' the Communist Party of Indonesia (PKI) and 'cut out' the 'communist cancer.' While the Indonesian army is identified as the primary orchestrator of the mass murders, the UK's alleged role involves incitement through covert propaganda rather than direct execution. Separately, declassified US documents indicate the US government's knowledge of and support for the Indonesian army's extermination campaign, though the direct incitement claim largely pertains to the UK.

STRONGEST CASE FOR

The strongest case for UK involvement in inciting the Indonesian mass murders rests on newly declassified British Foreign Office documents, as reported by several media outlets. These documents reportedly show British propagandists secretly encouraging the elimination of the PKI among anti-communists and army generals. The language used, such as 'cut out the communist cancer,' suggests a direct effort to galvanize violence. This aligns with a pattern of Cold War-era covert operations aimed at preventing communist takeovers, where propaganda and psychological warfare were common tools.

STRONGEST CASE AGAINST

The counter-argument would suggest that while British propaganda may have fueled anti-communist sentiment, attributing direct incitement of mass murder to these efforts is a leap. The Indonesian army was already orchestrating the purges, and their actions could be largely independent of British influence. Furthermore, the reports primarily describe propaganda efforts, not direct orders for killing. The scale of violence and its execution were ultimately by Indonesian forces, raising questions about the extent to which external propaganda was the decisive factor in inciting mass murder versus merely supporting an already existing violent agenda.
