isolationism to becoming the "Arsenal of Democracy."
● Neutrality Acts (1935–1937): Prohibited selling arms or
making loans to nations at war.
● "Cash and Carry" (1939): Allowed sale of materiel to
belligerents if they paid cash and used their own ships (aimed
at helping Britain).
● Lend-Lease Act (1941): Effectively ended neutrality by
allowing the U.S. to lend war supplies to any nation deemed
"vital to the defense of the U.S."
● Atlantic Charter: FDR and Churchill met to outline post-war
goals (self-determination, free trade).
● Pearl Harbor (Dec 7, 1941): The "date which will live in
infamy" that triggered a formal U.S. declaration of war.
2. The Home Front: Mobilization & Economy
WWII officially ended the Great Depression through massive
government spending and industrial production.
● War Production Board (WPB): Directed the conversion of
peacetime industries to war production.
● Rationing: The Office of Price Administration (OPA) regulated
consumer goods (meat, sugar, gasoline) to ensure supplies for
the military.
● Financing: The war was funded through increased income
taxes and the sale of War Bonds.

posters and film to encourage patriotism and sacrifice.
