I thought the japs attacked Pearl because the US (then the saudi arabia of oil) embargoed oil to Japan.

“In addition to military support, the US, Britain, and the Netherlands East Indies initiated oil and steel embargos against Japan in August 1941.
Moving Towards War with the US
The American oil embargo caused a crisis in Japan. Reliant on the US for 80% of its oil, the Japanese were forced to decide between withdrawaling from China, negotiating an end to the conflict, or going to war to obtain the needed resources elsewhere. In an attempt to resolve the situation, Konoe asked US President Franklin Roosevelt for a summit meeting to discuss the issues. Roosevelt replied that Japan needed to leave China before such a meeting could be held. While Konoe was seeking a diplomatic solution, the military was looking south to the Netherlands East Indies and their rich sources of oil and rubber. Believing that an attack in this region would cause the US to declare war, they began planning for such an eventuality.”
And we placed an embargo on Japan because of their war on China, and occupation of French territories in Asia.
