World War II

I think it is interesting how all the countries allied together to create and maintain power in case the countries were at war. Germany had secret allies. Together all those allies were trying to dominate and control certain countries and regions of the world. Germany secretly allied with Japan, which attacked the U.S creating tension with many of the various countries in the World. The World war began because of Germany. Many of the wars created, lives lost, tension, insecurities and financial debts. Germany was rightfully blamed. But, if Germany was not blamed and made to pay all the debt the destruction brought, then Hitler probably wouldn't have risen to start another war. It was also, interesting to see how Hitler was able to manipulate other countries to believe in what he was doing. The idea that there was a dominant race with certain physical characteristics might have turned some countries against Germany. I wonder how he even came to think this. Why did he believe this? Why does the dominant race have blonde hair with blue eyes?
