On December 7, 1941 at 0755 hours the entire US Pacific Fleet (which included 18 US ships, 300 airplanes and 42,000 sailors and soldiers) moored and stationed at Pearl Harbor, Honolulu, Hawaii, was suddenly awakened and forced into war by Japanese air and naval forces. Since the United States had already demonstrated its opposition to Japan's territorial expansion plans in China and Manchuria by openly and directly imposing embargoes and blockades, Japan interpreted this as an obstacle to their economic plans and an act of war against their military forces . As a result, the Pearl Harbor attack changed the course of history and demonstrated that effective diplomacy should only be used when the end result is feasible for both sides. Before the order to attack Pearl Harbor was granted and Japan decided that war against the United States and Japan Allied Forces were eminent, Japanese leaders trained their naval and air forces months in advance before the attack as they positioned themselves and formed alliances with nations that shared their vision of expansion through treaties, such as the Tripartite Pact with Germany and Italy of September 27. , 1940. “The Imperial Navy, he continued, should have ferociously attacked and destroyed the United States main fleet at the beginning of the war, so that the morale of the United States Navy and its people” would sink “to such a level that cannot be recovered” (Major Disasters Pearl Harbor 48). Furthermore, Japanese leaders as they prepare for war continue to use diplomacy as a way to mislead their true intentions. “They agreed on three main issues: first, that Japan would indeed continue to prepare for war while diplomatic negotiations continued” “One by one they slipped away, seemingly at random… into the middle of the paper… .and Japan to force the United States into World War II without clearly proving that the United States could have avoided the attack on Pearl Harbor through more effective diplomatic strategies and resources. Ultimately, the surprise attack on Pearl Harbor was effective but not as devastating as Japan intended and Admiral Yamamoto had planned this. As a result, the United States lost 18 battleships, 300 airplanes, and 2,500 sailors and soldiers; however, Japan left its oil storage depots, shipyards, and submarine docks intact; and all aircraft carriers. This allowed the United States to quickly recover in the war and Japan, instead of achieving victory, realized the sleeping giant they had awakened. Unfortunately, our US leaders have not learned to avoid diplomacy where arrogance and radical ideologies are imperative and necessary for those who attempt to overtake and cripple our democracy..
