So here's the key question: how many more Americans are you willing should die once the Ruskies are out of the fight?
And just to make it interesting, suppose some of those extra dead Americans were your grandfathers, or other close relatives -- how many of them do you want to sacrifice?
I'm certain that's precisely the question President Roosevelt asked himself -- for maybe two seconds -- before deciding it was much better to let the Soviets die killing Germans than make our guys do it.
So instead we had the embarrassing spectacle of FDR kissing "Uncle Joe" Stalin's *ss and giving him whatever he wanted to stay in the war -- and not make a separate peace just like those same Communists had done in the First World War.
We probably would have sacrificed less had we concentrated on defeating Japan first while letting the Nazis and Soviets slaughter each other - then we could have hit the weakened Germans. In effect, the Soviets did this when the stayed out of the Pacific war until we effectively defeated Japans; then they attacked the retreating Japanese in Manchuria and Korea.
