War Comes to America

This section of the film concludes with a lengthy paean to American inventiveness, economic abundance, and social ideals.

The film examines how American public opinion gradually changed from one of isolationism to one of support for the Allied cause and demonstrates this using a series of Gallup polls.

In 1936, public opinion is firmly isolationist, with 95% of Americans answering NO to the question "If another world war develops in Europe, should America take part again?"

That increase in pro-Allied sentiment triggers Lend Lease aid to the United Kingdom (and to the Soviet Union after it had been attacked by Germany).

Towards the end, the film argues in detail (to a backdrop of animated maps and diagrams) that American involvement in the war is essential in terms of self-defense.
