But TROJAN wouldn’t prevent the Red Army from conquering Europe and the Middle East. Nor would it lead to the collapse of the Soviet Union. “For the majority of Soviet people,” the committee noted, “atomic bombing would validate Soviet propaganda against foreign powers, stimulate resentment against the United States, unify these people and increase their will to fight.”
It would definitely piss them off, but would they fight or stand down? The prospect of overwhelming, annihilating force, with no real outlet for vengeance, may well have broken them. I'm not convinced they would continue to fight, knowing that resistance meant the destruction of more of their cities.
Too late to test it now, as the anger would lead to retaliatory strikes from the Russians on American cities.
