And the world would have been a better place? No, that's why they were wrong.
The point is Americans always been skeptical of foreign involvement even in 1941 (the war started in ‘39).
And given Europe's headlong rush to import Jew hating muzzies and embrace fascism presently, it might have been better off under Hitler.
It's probable that he would have been toppled by the 50's.
Making the world “a better place” doesn’t appear in any version of the Constitution I’ve ever seen.
