And the threat. Don't forget the threat.
McArthur was fired for the very same reason we used nukes. The thing the General forgot, and Harry forgot was that "The object of war is peace." Not unconditional surrender, peace. Don't forget about the Paris meetings to discuss "terms of surrender." And for heavens sake, let's not forget that we told them, "You surrender unconditionally or we will use the Bomb on Tokyo next." The bluff worked, we'd already blown our wad by then.
You can make the claim that "well, gosh, we didn't really know how bad it would be" on the first one (an argument I find reprehensible, for if you don't know what's going to happen, why use it on a city at all?) but you cannot make that claim for the second one.
(Aside: In an advanced placement history class way back in high school, I successfully prosecuted Harry for war crimes - it may have been my finest hour ;-)
