dawg the USSR fought the nazees the most and yea revolution requires a violent uprising, how else do you think we can get the workers power back from the rich and the state? you thing that peacefull protest can do that its all js respectabilty politics that only serves the ruling class, the rich and the state will never give any power to the people without violence
ussr fought against the nazees but then formed a pact with them to fight against the western powers so that's one thing. there were mass killings including 3xecutions, famine, d3aths through forced labour, deportation, starvation and imprisonment under communist regimes. communism is not a bad system in theory but it has many flaws making it inferior to other forms of governments used today.
