Explain why the US issued an embargo on Japanese trade in 1941?

The U.S. issued an embargo on Japanese trade in 1941 primarily in response to Japan's aggressive military expansion in Asia, particularly its invasion of China and occupation of French Indochina. This action was intended to curtail Japan's access to vital resources, such as oil and steel, which were crucial for its war efforts. The embargo aimed to pressure Japan to withdraw from its aggressive actions and prevent further conflict in the Pacific. Ultimately, this economic sanction contributed to escalating tensions that led to the attack on Pearl Harbor in December 1941.
