The SOB's wouldn't be a nation today without our help and without living under our nuclear umbrella. Let 'em vent all they want, wait until someone attacks them and see what happens.
My high school world history teacher lived in Japan for several years, and said a large number of Japanese who were alive at the time of the bombing told him that every horrible thing he'd heard about the cost of an invasion was either true or fell short of the truth. Even many Japanese who resented the bombing on some level agreed with Mitsuo Fuchida, the air commander of the Pearl Harbor attack, who said that any leader who had such a weapon and held it back would be a man who had fundamentally broken faith with his people.
