Explanation:

The US adopted isolationism before WWII mainly to avoid American involvement in foreign conflicts. The large number of casualties in WWI (not Spanish Civil War, which was later) made Americans wary of foreign wars. The desire to help Americans travel or the Spanish Civil War casualty count aren't key.
