Why did the United States support Indonesia’s brutal 1975 invasion of East Timor?

In short: When Indonesia invaded East Timor in 1975, it triggered a quarter-century of occupation that claimed one-third of the population. Behind the scenes, the United States provided crucial diplomatic support, driven by Cold War fears of communism and a desire to maintain a strategic alliance with the Indonesian regime.

The conflict originated in the power vacuum left by Portugal’s 1974 Carnation Revolution. As Portugal moved to decolonize, three main political factions emerged in East Timor: the pro-independence Fretilin, the conservative UDT, and the pro-integration APODETI. While Fretilin gained significant popularity through social programs, Indonesian President Suharto viewed the movement as a dangerous communist threat that could destabilize the region and embolden domestic separatists.

Indonesia launched a covert destabilization campaign called Operation Komodo, using radio propaganda and training APODETI fighters to sow discord. By August 1975, Indonesian intelligence successfully manipulated UDT into launching a preemptive coup against Fretilin. When Fretilin defeated the UDT forces, Indonesia shifted from political subversion to direct military action. On December 7, 1975, Indonesian forces launched a massive naval and aerial assault on Dili, marking the start of a long, violent occupation.

The U.S. administration, led by President Gerald Ford and Secretary of State Henry Kissinger, was fully aware of Indonesia's intentions. During a meeting at Camp David in July 1975, Suharto made his plans to integrate the territory clear. Kissinger, fearing a domino effect following the fall of Saigon, encouraged the annexation, viewing Indonesia as a vital, non-aligned strategic partner. This geopolitical calculation provided the diplomatic cover for an invasion that resulted in an estimated 100,000 to 180,000 deaths from conflict, disease, and starvation.

The occupation faced persistent resistance, particularly in the mountainous interior, until the Indonesian military secured advanced weaponry in 1977 and 1978 to crush the insurgency. The status of the territory remained a point of international contention for decades. It was not until 1999, following the ousting of Suharto, that the East Timorese voted for independence in a referendum. After a period of United Nations transition, East Timor finally achieved full sovereignty on May 20, 2002.
