Final answer:
The Japanese attack at Pearl Harbor was successful due to surprise, careful planning, and the timing during peace talks.
Step-by-step explanation:
The Japanese attack at Pearl Harbor was successful because it caught the U.S. by surprise, was carefully planned in advance, and took place while peace talks were still going on. The attack on December 7, 1941, was a devastating surprise for the United States as they didn't expect such an offensive move from Japan. The Japanese had meticulously planned and coordinated the attack, focusing on crippling the U.S. Pacific Fleet, which provided them a significant advantage. Additionally, the attack occurred while peace talks between the two countries were taking place, causing confusion and making it harder for the U.S. to defend against the attack.
