I know. Should have said STAYED allied with the Soviets. Barbarossa was a huge mistake. He might still have won, however, if had taken Moscow in the Fall, instead of diverting his armies South.
Getting Japan to agree to kick in the back door would have been helpful as well.
Do you think Stalin would have quit even if he had lost Moscow? That loss didn't finish the Russians when Napoleon invaded.
The alliance with Soviet Russia was always one of convenience, and everyone realised it. They both needed it because they both hated Poland and wanted to dismember her. Later Hitler needed it to protect his rear while he dealt with the French, and Stalin needed it to buy time to rebuild the red army following the purges and the debacle in Finland. There was never any doubt that the two would be at war with one another. They were total idealogical opponents for a start off, and Hitlers grand plan was for “lebensraum” (living space) in the East. Inevitably that meant war with the Russians.
Stalin was planning on being ready to attack Germany by 1943.
There would have inevitably been war between the two, the question is, who would throw the first blow.
