Try to catch this documentary movie. It has won the BAFTA Award. It has been nominated for the Oscar.
Maybe someone will upload on Youtube.
Or eventually they will show on History Channel.
It is about the massacre from 1965 to 1966. About 500,000 to 1 Million killed, mostly Chinese.
At that time Indonesia under Sukarno was greatly influenced by communist doctrine.
USA was worried about SEA becoming a communist block.
Regime change. Did not hear USA protesting loudly about the killings.
USA subsequently gave billions in aid and military assistance to new Suharto regime.
That's the real world. These things happen. Anyway it is history by now.
