2. Summar y
The attack on Pearl Harbor was a surprise
military attack by the Japanese Navy
against the U.S. naval base at Pearl
Harbor, Hawaii on the morning of
December 7, 1941. The next day, the U.S.
declared war on Japan, marking their entry
into WWII.

3. Cause of t he At t ack
 The surprise attack on the U.S. was intended as a preventative
measure that would keep the U.S. fleet from influencing the war that
Japan was planning on Britain and the Netherlands.
 There was tension between the U.S. and Japan prior to the attacks.
Japan invaded China in 1936 when the U.S. and China were allies.
 Japan wanted to be self-sufficient in resources such as coal, rice and
rubber. Unfortunately for them, the U.S. occupied the Pacific where
these resources were found. Years before the attack, the U.S. had
limited their trading with Japan and persuaded other countries to do
the same.
 Japan felt “entitled” to the Hawaiian islands because of their race and
“genetic superiority”.

 Pearl Harbor was attacked at 7:55 am by a total of 353 aircraft

5. Resul t s

and the U.S. government did not hesitate to declare war
on the Empire of Japan, thus becoming a part of WWII.

disappeared.
 Germany’s declaration of war on the U.S. moved the
United States from support of Britain into active alliance
with the Allied Powers.

immediately after operations against Japan began.
