Patton was right....we should have just kept rolling over those bolshevik b*stards!
Physically impossible: 1. we didn't have the backing of our allies 2. we had a supply line of the Atlantic and half of Europe while the Soviets' supply lines would have shrunk 3. the Soviets had more divisions (about 1.5 as many), 4. they had air parity and armor domination 5. we were still at war with Japan 6. after dropping the second bomb on Japan we didn't have another bomb for 4 years. US has very little Uranium.
