>>2452938>Communists… well, they usually want to meddle everywhere, right? Not as much as you think actually. One of the problematic things about communism in the 20th century is that you had a lot of communist parties basically follow the USSR, but the Soviet government more and more subordinated communist ideology to the interests of Soviet realpolitik over time (this gets controversial though and there are all kinds of debates about this), which more or less precluded revolution in Western capitalist countries because that would mean World War III. I mean a communist revolution in France for example. Now that's a different matter in Angola.
This could also be disastrous at times like the Molotov-Ribbentrop Pact, which whatever you say about it as a pragmatic maneuver for the Soviet Union, did put Soviet-aligned communists in an awkward position because they were now under pressure to adopt a non-interventionist line for two years until Germany invaded the Soviet Union. Then communists were full win-the-war types. Also the most impactful communist victory after that was in China where the communist party there broke with Soviet direction in the 1930s. Also this might surprise you, but Soviet aid to the Chinese communists was much less than you might think. The U.S. provided a lot more aid to Chiang Kai Shek's forces than Stalin did for the communists.
>Do communists and libertarians agree on foreign policy? […] But then again, some leftist types claim to oppose imperialism too. So, do they line up sometimes, or is that just random? I honestly don’t know.The word "policy" is too narrow here because it implies something the U.S. government (say) should adopt within the framework of the existing system. On the left, that's more of a social-democratic approach like Bernie Sanders or AOC. Like "we should reduce foreign interventions" because "that's harmful." And the solution is to change the policies. There are also libertarians who say things like that. Communists want to change things in a more fundamental and systemic way. The fact that U.S. engages in military adventures around the world is not an accident or a mistaken policy but something embedded in how the whole capitalist economic-technological system and its reinforcing social structure operates. It's more like a different framework for thinking about it.
