I seriously doubt we as a nation now could pull off what they did.
I pray we could rise to the occasion, but think it would take a direct threat to our nation and people to arouse the ire.
You would also have to overcome the liberal interference against the war.. Think Viet Nam on steroids!
there was a pretty big stay out of Europe movement in America prior to Pearl Harbor - led by Republicans. There were more German immigrants in this country than any other nation at one point
Roosevelt's efforts to get us into the war in Europe (to come to the aid of Britain) was actually an impeachable act.
