For the Einsteins here advocating dropping A-bombs on the USSR (twelve even!):
1. The USA didn't have 12 A-bombs AFAIK.
2. The USSR wasn't seen as a big baddie back then. The heroic fight of the Red Army had filled the American papers for years and Stalin didn't mean "big mass murderer and enslaver of people" back then. Dropping bombs on the USSR wouldn't have been possible in this context IMO.
