President Franklin D. Roosevelt addressed Japanese aggression by implementing economic sanctions and diplomatic measures, responding to Japan's expansionist actions in Asia during the Hoover administration. He enforced an embargo on oil and other critical materials, which aimed to curb Japan's military capabilities. Additionally, Roosevelt sought to strengthen alliances in the Pacific, particularly with China, and increased military preparedness. These actions ultimately led to heightened tensions, contributing to the outbreak of World War II in the Pacific.
