In a way, the actions against the communists in Indoneasia mirrors what went on in Chile and several other nations and the US’s reaction to it. While massacering innocent unarmed civilians is inherrently wrong, there was a Cold War going on. If the communists in these countries had been unimpeded, they probably would have ensured equal if not worse tragedies to say nothing of the end result of the Cold War.
We called it a Cold War but it was quite hot in many places. In reporting it things were all compartmentalized and it was made to appear as different local actions, but it was all the same war, from Argentina to Ethiopia to Indonesia and Vietnam.
