USSR was founded in 1917 and based on my rough count it looks like majority of the famines in time period were conducted by communists regimes.

This seems like a what aboutism. I am not going to disagree that capitalist regimes didn't cause famines for funsies like like commies did but recent time frame comparisons show communist did do it more frequently.

Especially once you account for the fact that have been very few comminist regimes, and they all of that that came to lower via a "revolution" ie brute force used famine as tactic to pacify the peasants.
