During World War II, over 200,000 Filipinos fought in defense of the United States against the Japanese in the Pacific theater of military operations, where more than half died. As a commonwealth of the United States before and during the war, Filipinos were legally American nationals. With American nationality, Filipinos were promised all the benefits afforded to those serving in the armed forces of the United States. In 1946, Congress passed the Rescission Act () which stripped Filipinos of the benefits they were promised.
