Stalin has the quote about disarming his adversaries; what evidence do you have to show how his program of disarmament worked? Why did he have to disarm them if Lenin already did? (Answer: Lenin didn't). Why did Khrushchev have to disarm them a third time? Surely at least some Russian peasant farmers owned rifles, gun regulations or not. What role did this disarmament play in Stalin's rise to power? It appears minimal and attenuated to me.
I'll go on if you provide a shred of support for your talking points.
