This is a very in depth question to which a short, simple answer is attempted here.
Japan was involved with a war on the Chinese mainland. A US embargo of sales of strategic materials to Japan threatened the Japanese economy. The Japanese felt that the US was trying to stop their military activity by curtailing the resources they critically needed. This led to Japan looking to conquer areas containing strategic raw materials to make itself self sufficient.
The European powers, UK, France, Belgium, etc. held as colonies those regions it would need to obtain this independence. They were involved in the European War and would not be able to oppose Japanese takeover of their Pacific and far eastern colonies.
The US, however, was a major military power not yet engaged in war, and with substantial interests in the region, including the Philippine Islands, then scheduled to receive independence from the US in 1946.
The decision was made to preempt US involvement by making key strategic strikes at the US bases in the Pacific as part of the makeover of European colonies.
As for how it affected the European War, the Axis never tried to coordinate their actions as the Allies did. The primary impact on the European war was that the US became a belligerent there as well as against Japan. If Japan had not attacked the US, it is possible that any US involvement in the European war would have been delayed so long as to lead to the fall of England and perhaps a peace with the Soviet Union.
If the Axis had coordinated, things might have turned out differently. If Japan had attacked the Soviet Union, key resources that Stalin released to stop the German drive on Moscow would not have been available. "Germany first" was the decision of the Allies once the US became an active participant.
Japan made enemies in the US.
The Japanese attacked America by aerially assualting pearl harbor the reason is i believe Germany put pressure on japan forcing japan to attack pearl harbor
there wasnt really a conflict that caused Japan to attack the US. the US was not at war with Japan until after Pearl Harbor, in which the Japanese were the aggressors.
Because Japan planned and carried out the attack.
Japan attack Pearl Harbor after warning the US of an attack.
Germany didn't attack pearl harbor dumb***, that was japan
China did not attack Pearl Harbor, Japan did.
The attack caused the United States to end its neutrality & declare war on Japan. ******* Note: a few days later, after the Pearl Harbour attack, Hitler declared war on America, so bringing America officially into the European war.
The Whole Harbor, on December 7th, 1941
The empire of Japan
Pearl Harbor, HI
Weeks before the attack.
You have some serious reading to do. Pearl Harbor did not attack Japan. The US Naval Base at Pearl Harbor HI was attacked by the Japanese on Dec 7, 1941. The American ships were tied up at their morring points in the harbor, and there had been no declaration of war. This was an unprovoked attack by Japan on the United States.
start of the pearl harbor attacki my is Dennis i think the attack on pearl harbor was caused by the us not doing trade with japan.
no pearl harbor was part of America and pearl harbor was bombed by japan
Japan had the resources for an attack on Pearl Harbor. They simply needed more resources to continue the war.
