I think the issue might not be whether the US should have gotten involved in WWII but the extent which we supported Russia. Perhaps we should have made the Russians bleed a lot more so we bled less?
Sorry but that just dont fly. The Russians were DONE bleedng by the time we got more than our big toe n the water! Sorry, not to knock on us but, truth is truth like it or not.
It must be remembered that Stalin signed a non-aggression pact with Hitler on August 23, 1939, and he's not the one who broke it. If Hitler had kept up his end of the bargain, Ol' Smilin' Joe would have been happy to stay his pal.
I mention this because there are people out there who seem to believe that Stalin scripted the entire thing (somehow including Hitler's invasion) just so the Commies could be allies with the West.
It was Hitler who made the Commies and the West into allies.
