The "neutrality" that the U.S. and allies instituted was more like a blockade. It was a dumb move on our parts. We should have been there to support, and protect the Republic. Had we done so, some historians believe Hitler wouldn't have had the guts to set his sights on conquering Europe, and the Soviet Union would have never come to be. I think he still would have made the attempt, but have been beaten long before he was, and the USSR wouldn't have existed.

Wolf, that's a big historic stretch, to put it mildly. "Protecting the Republic" within the given historic context borders insanity. The US had many other pre-occupations one of which was the political philosophy of isolationism. Spain and its "republic" was as historically far away to the US foreign policy as the moon is the the earth confused
