Like Soviet Union, PRC, DPRK, Viet Nam? From my understanding these weren't/aren't really ruled by the people but by a wealth(ier) elite, they use systems of money, have (limited) private property, etc.
Which, imo, is capitalism or (its friendlier variant) socialism (which has some communist features like universal healthcare for example), but is not communism.
Isn't the goal of communism supposed to be anarchist communism (no state [government], also no rich/poor divide)? Where nothing is owned, either by the state or by individuals?
I didn't think statism is compatible with communism.
Any socialist state needs to have a means of defending itself against reactionary intervention, whether domestic or international.
The US and other capitalist powers have shown that they will always attempt to intervene to prevent socialism from developing.
My main issue with Anarchism as an ideology is that it doesn't really provide an adequate answer for the question of self defense.
