Pearl Harbor is a harbor on the island of Oʻahu in Hawaii. On December 7, 1941, the Empire of Japan launched a surprise attack on the U.S. naval base at Pearl Harbor. The attack damaged or destroyed numerous U.S. battleships and brought the United States into World War II. The Japanese intended to neutralize the U.S. Pacific Fleet so that the U.S. would not interfere with Japanese expansion in the Pacific. However, the attack outraged the American public and united support for the war effort against Japan.

4. Many Different Reasons
• President Roosevelt had banned all exports of scrap
iron, steel and oil to Japan.
• The United States wanted Japan to withdraw from
Indo-China which they had invaded earlier.
• The US opposed Japanese expansion.
• The Japanese were motivated to expand their empire
and had to make a decision between surrendering or
going to war with the United States.

5. • Pearl Harbor was the home of the U.S. Pacific Fleet.
Japan did not want the U.S. in the war because the
U.S at this time had the greatest Naval force. They
thought that if the Pacific Fleet was destroyed,
Americans would feel demoralized and not want to
fight.
They made a big mistake
when they thought that
this might be a reason to
attack America!

10. Americas Reaction!
• This sneak attack against Hawaii brought an immediate
reaction of unprecedented unity from the American
people.
• Families from every class sent their sons and daughters
to war, women joined the industrial work force, and no
one was untouched by the effort to bring all of U. S.
resources to bear upon the war effort.
• The U. S. war plans strategy had been "Europe first",
but the Japanese attack caused a far greater effort to
be directed early on to the pacific.
• It fueled the will of the U. S. to completely defeat Japan
regardless of the cost.

Austro-Hungarian and Ottoman Empires) had
