Timeline is correct. But Mao and his commies had been fighting the japs since the 30s. The USSR's "original states" were under Moscow (Stalin) well before 1939. Too bad we can't prove a negative had the west not aided Russia or the Chinese would they have been able to defeat the krauts and the japs..
I seriously doubt if Russia could have handled Germany without the T-34 tank,...which was a copy of an American design which had been rejected by the American military.
Wrong. The T34 had a Christie suspension, but that's it. It was not a copy of an American design.
Its suspension was the heart of the T-34.
No, that would be its sloped armor and 76mm gun, which punched through most German armor. The suspension merely allowed it higher cross country speed.
