I'm interested in what it means to you to "press the socialism button" or to "maintain power". There's some line that needs to be drawn.

After reading that list, it seems peculiar how you start Vietnam at 1945 but not Laos, how you start Cuba at 1975 instead of 1959. And that's leaving alone how the USSR was largely a successor state to the Russian Empire and was the result of the same party/faction operating in different "national" contexts but the same state context.

In some of the cases on this list it was a consolidation of power in a revolutionary context, rather than toppling a bourgeois government.

Is the line drawn at a successful revolution, or is the line drawn at winning an election, or something else entirely? And where do examples like Ghana and Zimbabwe (and maybe Nepal and a few others) fit in?
