That I've read about, the USSR went through at least two famines due to government malice or stupidity.
Mao starved millions by sending vast amounts of Chinese-grown food off to the USSR.
The We Are The World famine in Ethiopia was Socialist government caused.
Kim II and Kim III (not sure about Kim I) have kept NoKo in a state of near starvation and starvation for at least a couple of decades.
The point of commonality? All are various forms of Marxian Socialism.
