I love history. Thats why I wanted to post this thread. I had a feeling we would get deeper into WW2. So here is some more.

Hilter wanted to be personally in charge of certain (maybe all) Panzer units. During Operation Overlord, a Panzer division sat in reserve of the Axis Atlantic wall. Had Hitler not been asleep, he could have ordered the unit to attack and could have pushed the Allies back into the English Channel.
HItler declaried war on the US after Pearl Harbor. All the did was move 100s of US 4 engined bombers to England, which soon leveled all of Germany and all of her industry.
Hitler didn\'t want to be on the defense. He always wanted to be on the attack. Therefore he personally made the decision to produce more bombers (ju88s, etc)instead of defensive fighter aircraft (bf109s and fw190s). He also personally made the decision to strap 2 bombs on the belly of the first operational jet fighter, the ME262, and force it into the JABO (ground attack) role.
Hitler had to approve every weapon that went into service. This included small arms. It\'s rumored that he had a thing for submachine guns (machine pistole - MP40). When designers introduced to Hitler the worlds first assault rifle, he denyed it. The designers then changed its name to the MP44 and Hitler approved of the project. The STG44 would have been in the hands of German soldiers in 1942 if it had been approved earlier than Hitler let it to be.
Those were only 3 mistakes, Im sure he had many more also from poor military stradegy.
