“Another 186,xxx died due to killings.” Makes sense.
Their is no doubt that the communists in Indonesia were backed by Russian and China. Killing off the communists and back Soeharto gave Indonesia a whole new direction and opened it to US and the west and drove out the Soviets.
This was part of the containment and reversal strategy in Asia.
I started working with Indonesian business’s in 1971 while based in Asia and helped to organize and develop one of the biggest private companies there. That company now has hundreds of “middle class” employees.
