Question

What did President Roosevelt bring together to create what he called an "arsenal of democracy?"

I believe it is Liberty ships, planes, weapons, and supplies for the military produced by corporations.

Answer 2

liberty ships,planes, weapons and supplies for the military produced by corporations

Answer 3
