Why did the Japannese bomb pearl harbor?
Japan was in a war to expand their empire. They needed raw material to keep their war machine going. They wanted to take over the east indies for their rich oil reserves. The US didnt agree with what they were doing so we stopped sending them oil. The Japanese wanted the oil anyway and were afraid that the Pacific fleet of the US would hinder their ability to access these islands for their oil. So they decided on a sneek attack hoping to catch the US carriers along with the capital ships in Pearl Harbor and sink them. Thus taking the US fleet out of commision for many months. This would allow the Japanese to continue on with their war effort. However, the carriers were out to sea on some exercises and the Japanese didnt sink one of them on that day.
