Actually it was the Mongol Fleet under the direction of Kublai Khan that tried to invade Japan twice but was destroyed by the "Divine Wind". I agree with VTF1, we should not judge a nation or its people are "bad" or "good". We can't said that all the Japanese or German were "bad" collectively because of their govt policies during WW2. I am certain that portions of Japanese or German populations were against the war. A few good example are Claus Von Stauffenberg and Oskar Schindler, they are Germans but they are tried to do the morally right thing. Every race or nation have their bad apples. Individuals rather than "nations" or its "people" should be judged whether they are "good" or "bad".
