The genocide of communists and others started Suharto's authoritarian regime, and he continued to oppress and kill for decades, often with the help of the United States and people like Henry Kissinger.
When Indonesia invaded East Timor in 1975 killing over 200,000 civilians the US provided weapons and diplomatic cover. Ford and Kissinger met with Suharto the day before invasion, giving a green light. The US blocked UN action for decades while genocide continued.
