Hitler lost the war when he invaded the USSR. He did not have the resources to fight a 2 front war.

If he had not brought the US in and they then supplied the USSR with food and ammo then he would not have had such a time in the USSR. They had little food, little ammo and Stalin had shot his best generals.

The commies had treated everyone so badly that they were ready for a change in government. Of course Hitler began to treat them every bit as badly and so that advantage vanished.

He really was stupid.
