Enemies of the state?

In 1917 Woodrow Wilson's Congress enacted the Trading With the Enemy Act to regulate—not forbid—trade with belligerent nations. The language of this piece of legislation defined precisely who was, and who was not, an enemy of the United States. Specifically excluded from that classification were the citizens of the United States. That was an oversight that would be corrected three days after Franklin D. Roosevelt assumed the mantle of the presidency on March 6, 1933.
