9. Hitler dismissed all the right technologies:
Hitler could have won the war against Soviet Union if he would have acknowledged the right technology. But, he gave up many of the most useful innovations of that time including the cancellation of the first ever assault rifle, which was perfect for the Russian vast lands. Also, Me-262 fighter jets, the first jet powered aircraft was discarded by him. Since the early deigns of the fighter jet were that of an interceptor, and Hitler never wanted interceptors the project was smacked out.
8. US joining the World War II in 1941:
During 1941, Japan attacked the US at Pearl Harbor marking America’s entry in the World War II. As a promise to Japan, Hitler also announced war on America, but just the way it underestimated the British and also the Russians, it thought that reeling under the loss of war, America was incapable of defeating Germany. And what happened ahead proved him wrong.

7. Hitler became Commander-in-Chief, neglecting all advice:
By the time Hitler sensed the total failure of Operation Barossa, he had inculcated a lack of trust for all his generals and their abilities. Hitler lost as his mistrust grew so grave that instead of devising new strategies to gain back the defeat, he appointed himself as the Commander-in-Chief of the army. He thought he could undo their failures and plan better. Advice from the many wise Generals of Germany could have saved the German army.
