And who condoned that all; who actually put Lenin in power (and spare us the "Germany Government" crap), and then did not put neither him nor his equally-or-more dictatorial successors out of it again after they noticed that the results were shit?

The Russian people, that's who. Any regime that is tolerated by its people is always and everywhere the responsibility of that people. Whose the Hell else could it even be?!?

And this is so fucking self-evident that even trying to argue against it seems a surefire sign of advanced lunacy.
