War with Japan

Tensions between Japan and the United States were rising in the prewar era. Due to Japn's actions in China and Machuria, FDR has frozen all Japanese assets. He knew if he made some sort of embargo that entirely restricted oil to Japan. But an embargo was devasting to Japan they were reliant on the nited States for about 80% of their oil. After failed  diplomatic discussions, Japan took action against the U.S. through an attack on Pearl Harbor setting off US conflict with Japan. Therefore, it is plausable that even without conflict in Germany, Teh United States would have engaged in war in Japan.
