What if the alternative was for the U.S. to firebomb and blockade Japan for another year and then with Russian help invade. Over twenty times as many Japanese would have died, a million Japanese women could well have been raped by Russian troops, and one-have of Japan would probably have had to live in a communist dictatorship for at least 40 years. Would you really prefer this alternative to what actually happened?

Or even worse, what if the alternative was for the U.S. to use biological and chemical weapons on Japan and kill most of its population?
