What was the American involvement in the war at this point (May, 1941)?

discusses "Tricycle," the code name for a Yugoslav named Dusko Popov. He was a double agent and was ordered to the United States in June 1941. TRICYCLE delivered information of a planned Japanese attack of Pearl Harbor, using the tactics the British had used at Taranto. J. Edgar Hoover did not find TRICYCLE to be credible and he was moved to Camp X. In August 1941, Roosevelt and Churchill met on Navy ships. Roosevelt wanted to come into the war and was looking for an act of provocation that would justify it.
