Yes yes yes........Hitler could had ruled the world if he was smart in long-term strategy....he made his own decisions in Operation Barbossa.....that led to his eventual defeat, at the expense of the Russian people.
however, Hitler was a very smart man in commanding the masses. Millions upon millions of German citizens followed him, the Austrians supported him, and France and Britain did nothing, which was very stupid, as you know. Basically Hitler was lucky, in most respects. He couldn't had gained power without the Great Depression, and he couldn't gain the support of the people, when he came to power without certain people.
So, basically Hitler was very smart who was very one-sided.
