Why We Fight

Why We Fight is a series of seven propaganda films commissioned by the United States government during World War II to justify to American soldiers their involvement in the war. Later on, they were also shown to the U.S. public to persuade them to support American involvement in the war.

The series faced a tough challenge: convincing a recently non-interventionist nation of the need to become involved in the war and ally with the Soviets, among other things.

Why We Fight was edited primarily by William Hornbeck, although some parts were re-enacted "under War Department supervision" if there was no relevant footage available. The animated portions of the films were produced by the Disney studios – with the animated maps following a convention of depicting Axis-occupied territory in black.
