Your "no u" line about how actually I am telling children's stories doesn't work as well as you think it does. The crux of my case is that these states aren't monoliths and potemkin villages but actually have complex internal politics where people of varying viewpoints are able to openly disagree and protest, as is observably true in these countries! Not everyone in the Russian legislature supports the war, and they generally did okay with this position. There are all sorts of left/right debates in China among various politicians and journalists and so on. To call this kabuki theater or totally inconsequential without any actual evidence is silly.

Also your timeline is bad. The Great Famine ended circa '61 and the Cultural Revolution began in '66. The Cultural Revolution certainly had its issues, but it didn't cause a famine. Deng did end the Cultural Revolution, sort of, but only after Mao's death and the purging of the Gang of Four (prior to Deng's re-ascent).

As an aside, I don't think Deng was ever imprisoned in connection to the Cultural Revolution, though he was half-purged and assigned to menial duties in one case and basically paid leave in another. It's quite interesting how pissed Mao and his clique were at Deng and yet they held their hand, relatively speaking. Wasn't it supposed to be a death sentence to oppose Mao, as the liberals tell it? Of course, Mao took pride in trying to rehabilitate people (even the last Chinese Emperor and captured Japanese soldiers!), so he would in almost all cases resist having someone killed or left to rot in prison.

There's a wild bias in western media in trying to make a Khrushchev out of Deng, but Deng himself vociferously refuted those comparisons while in office, calling Khrushchev a fool, a traitor, and so on, and saying that being compared to Khrushchev was an insult (which is true).
