Soviets would have done Hitler in eventually.
After Britain was swallowed up... I'm sure glad we didn't have to depend on the Soviets for our defense.
Ok, so it would have been ‘their’ barrel of the gun.
Umm no actually not. Without American trucks to motorize and supply a good chunk of their army, American rails and locomotives to rebuild and run their rail lines. American boots to cloth their soldiers and American food to feed them, American tools and repair facilities to keep their weapons going, the Russians probably would of signed a compromise peace along a line some where in Belorussia. They would of simply run out of the ability to supply and move their armies.
The Russians won the war eating American food, wearing American made uniforms, supplied by American made trucks and rail lines. American won the war on the back of Russian soldiers. Neither would of won without the other.
Ah, No... we were able to split Hitler's focus to multiple fronts and bomb the hell out of his infrastructure, basically cutting off his resupply lines to the eastern front.
