The western front was a U.S./British coalition in 1945. I suspect the Soviets would have 'went right through' the U.S. forces had Stalin thought it necessary. That would have been complicated by the fact that the Russians were largely using American supplied hardware such as Sherman tanks, and the fact that the Americans had the bomb and the Russians didn't. A struggle between the Americans and the Russians was every Nazi's dream in the closing days of the war, the idea being that the Westerners would stop fighting Germany and form an alliance against communism. However to the surprise of the Nazis and some Russians, the Americans and British loathed the Nazis far more than they loathed the communists at this time.
No, I'm not forgetting a "little place called Afghanistan." But it hasn't had anything close to the long-term social impact that the Kennedy/King assassinations had. Regarding the retinal scans ... I think you hear wrong.
This is all true, and the Russians may well have gone right through the US till they ran out of munitions. But you still fail to address what was so funny about my original post.
I guess you're aware the USSR was founded in 1922. You're probably referring to events there from 1945 to 1991.
