Even left-wing FDR saw the long term threat of Nazi Germany that idiots like you ignored in the 1930s until it was too late.
Your claims that we didn't fight for the Jews doesn't make sense since we didn't realize the Nazi Death Camps until we invaded Europe. You see if the police break down a felons door for drugs and find dead bodies in the basement, they just don't ignore the dead bodies....
You aren't very good at this. Coupled with decades of domestic free-enterprise economic policy, our pre-WWII non-interventionism is exactly why post-WWII US was history's greatest superpower possessing universal economic/military hegemony. An all-powerful status that is being evaporated thanks largely in part to the neoconservative hyper-interventionism you advocate.
