that usually ends in disaster. never mind the fact that authoritarian governments like the power and wouldn't want to give it back, which defeats the entire point of socialism...

but even if you have a completely benign dictator (usually just a fantasy but for the sake of argument let's say we had one) people, especially in democracies, don't like the idea of a coup, unless it's them doing it but then it's a revolution. but that could also lead to reactionary sentiment.

we've seen this happen in Iran. democracy gets fucked with by a US coup, people react with a revolution but unfortunately reactionary forces use the anger to their advantage and devolve into a different kind of authoritarian regime anyway.
