I just like how there was a period in the 1950's where the Soviet Union could have invaded the west with AK-47's and Main Battle Tanks while Europe and America were still largely armed with Bolt-Actions, Submachine Guns, and Medium Tanks.
I guess the Westerners (America especially) saw the Sturmgewehr fail to turn the tide of the war, and thus weren't in a rush to make their own Assault Rifles.
and they would have been vaporized by nuclear bombs.
