Patton spoke those words 78 years ago and not one word was in error. Patton was an outstanding general and understood war. Patton was an even better historian and understood the danger Russia presented to the world. We should have listened to him. When he spoke those words we had the atomic bomb, Russia did not. We would not have needed to fight them. We could have dictated the terms of their surrender. As mentioned above, we should have listened to Patton.
At the least we could have moved into the Central European countries occupied by the Soviet Union.
I don’t think invading the Soviet Union itself would have been wise.
Nuking the Kremlin in 1945 would have saved millions of lives in the second half of the 20th century. That would have ended the murderous gulags and Soviet genocides, no communist China supported by USSR, Korean War, etc.
