Hitler was like any Nationalistic leader. He wanted the best for Germany. After all that Germany went through because of the treaty of Versailles. He did what he did for the wellness of the Germans(except the holocaust). So why did he target Jews and if the holocaust didn't occur would his image today be better than what it is today?
