On which side was the united states at the beginning of ww2

Before even entering World War 2,The United States of America was neautral, meaning neither side. But everything changed after the Boming of Pearl Harbor by the invasion of the Japanese. That's why The United States of America declared war on Japan and entered World War 2. Have a fantastic day! ^_^

Britain and the Soviet union.
Remember...
BUS= Britain, United States, Soviet Union.
JIG= Japan, Italy, Germany.
Those are the two sides.
