I know historical hindsight is 20/20, but how did no one bully this guy into giving up his moronic "de-stalinisation" policy? Like the SU was built by Stalin and now suddenly hes satan incarnate? No wonder SU citizens lost faith in the party over time, how can you trust a bunch weather vanes?
There was obviously attempts internally as well as the fundamental splits of the PRC and Albania from the USSR on the matter, and the split of the general international movement.
But ultimately you can't just bully the men with power out of power, and the resistance from the people was scattered and able to be dealt with individually in turn, and there were plenty of opportunists prepared to take positions with Khruschev for personal gain or perceived stability.
