Answer: A. They carried out countless bombing raids on targets in Germany
Explanation:
Although World War II began in 1939, the U.S. only became directly involved when the attack on Pearl Harbor happened (December 7, 1941). However, developments required to provide military air support for Britain against the Nazis had started a long time before that.
By January 1942, with the U.S. working together with Britain's Royal Air Force, the Allied forces established the VIII Bomber Command to manage the air offensive against Germany.
