And also the Germans surrendered 8 May, while the Japanese surrendered 14 August. Over the course of that quarter it had become more and more apparent that WWII wasn't going to end soon (it didn't, in fact, end until 15 March 1991), and that the Soviets were going to be the next enemy, and that we'd need to preserve Germany and Japan in some form (rather than adhering to the earlier Morgenthau Plan, which would have rurified all of Germany, in the process killing millions and making it much easier for the Soviets to roll through Europe). If there were any fairness, we'd have hanged the Japanese emperor, and quite a few more of his subjects responsible for crimes against humanity. But the political-military situation didn't allow it.
