Winter

Yesterday in class, the irony of the worst winters in history were at the same time as the invasions into the Soviet Union. If Hitler would have checked everything during the invasion and calculated all of his advantages, he would have known about the temperatures during that time. But twice during both invasions? To me it sounds like the U.S.S.R even has the weather to prevent the takeover. Hitler needs to think more about his plans or hire someone to make them because he is not doing a very good job.
