Explanation:

The attack on Pearl Harbour by Japan during World War II was aimed at neutralizing and preventing it from interfering in Japan's military operations in Pacific Fleet, South-East Asia.

When Japanese bombers appeared in the skies over Pearl Harbor on the morning of December 7, 1941, the U.S. military was completely unprepared for the devastating surprise attack, which dramatically altered the course of World War II, especially in the Pacific theater.
