EXPLANATIONS BELOW
Concept note-1: -Immediately following the attack on Pearl Harbor in 1941, millions of men were called to duty. When these men joined the armed forces, they left behind millions of jobs. Instantly, the nation faced a labor shortage that was filled by workers who had previously been denied many employment opportunities.
Concept note-2: -America After Pearl Harbor On December 7, 1941, the United States was thrust into World War II when Japan launched a surprise attack on the American naval fleet at Pearl Harbor. The following day, America and Great Britain declared war on Japan. On December 10, Germany and Italy declared war on the United States.
Concept note-3: -WWII was fought on multiple fronts. A multiple front war divided the U.S. war efforts and fighting forces. The forces of the U.S. were divided between confronting Germany and Italy in North Africa and Europe and confronting Japan in the Pacific.
Concept note-4: -The need for labor opened up new opportunities for women and African Americans and other minorities. Millions of Americans left home to take jobs in war plants that sprang up around the nation. Economic output skyrocketed. The war effort on the “Home Front” required sacrifices and cooperation.
