A strange challenge idea that popped into my head:
Create a TL where Poland becomes a militaristic, totalitarian, “hermit kingdom” dictatorship. Average Polish citizen should have minimal contact with the outside world and propaganda should rally the population to defend their nation against the perceived threats of Poland’s twin eternal enemies – Germany and Russia. In a nutshell, Poland should mirror OTL North Korea as close as possible
I’m leaving the ideology of this TL’s Poland as well as the PODs that result in its rise up to you, but since this Poland is supposed to parallel OTL North Korea as close as possible, ideally the ideology should be Marxist-derived and the POD should be sometime in the Cold War.
