President Roosevelt asked congress for a declaration
of war on Japan after the December 7, 1941 attacks on Pearl Harbor.
On December 8, the Senate voted to support the request and the House
followed suite shortly after. Three days later, Germany and Italy
- fulfilling their treaty obligations with Japan - declared war
against the U.S. As the need for war materials increased, consumer
goods took a back seat to military production. Rationing began almost
immediately. In some states, nonessential use of gasoline was limited
to 3 gallons per week.
