A little History Lesson

I've been doing some research on WW2 lately and I've made some astounding discoveries. First of all; Hitler was not an idiot, or at least not in the beginning. Before he became corrupt with power during the war Hitler did amazing things for Germany. He gave them a fairly stable economy and brought the people together in a way very few politicians have ever been able to do. The other thing I noticed was what his three crucial mistakes were during the war. The first was how he dealt with Great Britain. It can be argued that if Hitler had continued his bombing of British air fields he might have won the war. Instead he changed his tactics to bombing the major cities in England and gave the Brits time to regroup. The second was declaring way against Russia. He made the same mistake Napoleon made. He thought that he could handle the frigid winters and harsh conditions and take the largest piece of land the world had to offer. Obviously he couldn't and he had to retreat. His third mistake was probably his biggest. After Pearl Harbor and the Us declaration of war against Japan, Germany declared War on the United States. This put Nazi Germany against Britain, the US, Russia, Canada, and all of the underground rebellion movements in the countries they invaded. There was no chance at victory at that point. I think that most people can agree that those were the most crucial mistakes and that it is a great thing that he made them.
