No, not without several bloodthirsty psychopaths reaching positions of supreme authority.
The Soviets were on their last legs when they made it to Berlin: supply lines stretched thin, divisions depleted, a desperate need to return to civilian production. They took so much industry out of all their occupied areas not just because they wanted to be pricks: their own country and its industry was utterly gutted by the Nazi invasion and genocide and it took their every resource to defend themselves. The last thing in the world they needed was a war with the west, with America still having vast resources to call on and a major headstart in the bomb race: the USSR knew the "secret" even before America sort of gave the game away but blowing up Hiroshima and Nagasaki, and had in fact encouraged their use, because they really didn't feel like invading Japan, for the reasons mentioned above.
