6 ships from United States Lines to repatriate Americans. On November 4, 1939 the Neutrality Act was signed into law which banned American ships from traveling to "'states engaged in armed conflict.'" and by early November 75,000 Americans had been repatriated from Europe. Internment In 1942 the War Department demanded that all enemy nationals be removed from war zones on the West Coast. The question became how to evacuate the estimated 120,000 people of Japanese ancestry living on the Pacific Coast of the continental United States. Roosevelt looked at the secret evidence available to him: the Japanese in the Philippines had collaborated with the Japanese invasion troops; most of the adult Japanese in California had been strong supporters of Japan in the war against China. There was evidence of espionage compiled by code-breakers that decrypted messages to Japan from agents in North America and Hawaii before and after the attack on Pearl Harbor. These MAGIC cables were kept a secret from all but those with the highest clearance, such as Roosevelt. On February 19, 1942, Roosevelt signed Executive Order 9066 which set up designated military areas "from which any or all persons may be excluded." The most controversial part of the order included American born children and youth who had dual U.S. and Japanese citizenship. In February 1943, when activating the 442nd Regimental Combat Team—a unit composed mostly of American-born American citizens of Japanese descent living in Hawaii—Roosevelt said, "No loyal citizen of the United States should be denied the democratic right to exercise the responsibilities of his citizenship, regardless of his ancestry. The principle on which this country was founded and by which it has always been governed is that Americanism is a matter of the mind and heart; Americanism is not, and never was, a matter of race or ancestry." In 1944, the U.S. Supreme Court upheld the legality of the executive order in the Korematsu v. United States case. The executive order remained in force until December when Roosevelt released the Japanese internees, except for those who announced their intention to return to Japan. Fascist Italy was an official enemy, and citizens of Italy were also forced away from "strategic" coastal areas in California. Altogether, 58,000 Italians were forced to relocate. They relocated on their own and were not put in camps. Known spokesmen for Benito Mussolini were arrested and held in prison. The restrictions were dropped
