No capacity? Every time I hear someone underestimate the Soviet ability to mobilize I get astounded.
Have 70 years of nuclear policy been based on a lie?

Ward Wilson, senior fellow at the James Martin Center for Nonproliferation Studies at the Monterey Institute of International Studies, explains that the Soviet declaration of war and not the Hiroshima nuclear bombing caused Japan to surrender at the end of World War II.

"The Soviet Union's declaration of war, on the other hand, fundamentally altered the strategic situation. Adding another great power to the war created insoluble military problems for Japan's leaders. It might be possible to fight against one great power attacking from one direction, but anyone could see that Japan couldn't defend against two great powers attacking from two different directions at once.
The Soviet declaration of war was decisive; Hiroshima was not.
After Hiroshima, soldiers were still dug in in the beaches. They were still ready to fight. They wanted to fight. There was one fewer city behind them, but they had been losing cities all summer long, at the rate of one every other day, on average. Hiroshima was not a decisive military event. The Soviet entry into the war was.
And they said this. Japan's leaders identified the Soviet Union as the strategically decisive factor. In a meeting of the Supreme Council in June to discuss the war in general, policy, they said Soviet entry would determine the fate of the empire.
Kawabe Toroshiro said, "The absolute maintenance of peace in our relations with the Soviet Union is one of the fundamental conditions for continuing the war."
The bombs didn't affect Japan's view on the war at all, the Soviets did.
