As big and strong and intelligent as the German army was, it wasn’t when it came to fighting on two fronts. When I think of WWII, Hitler and his army I think of how great good is over evil. The main motivator of good is the belief in God.
Had Hitler allied with Russia instead of fighting them, the allies would have been in a world of chit.
It's ironic how we felt we had God on our side (and I'm not saying we didn't) yet we were allied with the Stalinists, which is probably the most Godless regime ever in existence.
