United States Pacific Fleet Pearl Harbor Naval Base total war declared war on the United States and the British Empire Southeast Asia
Japan identified the United States Pacific Fleet based in Pearl Harbor Naval Base as the principal threat to its designs to invade and capture Southeast Asia. Thus Japan initiated the attack on Pearl Harbor on 7 December 1941 as a means to inhibit an American response to the invasion of Southeast Asia, and buy time to allow Japan to consolidate itself with these resources to engage in a total war against the United States, and force the United States to accept Japan's acquisitions. On 7 December 1941 Japan declared war on the United States and the British Empire.
