The War in the Pacific

Setting the Scene: September 1940: Japan joins forces with Germany and Italy in the Tripartite Pact (promised mutual support against aggression) Japanese expansion threatening US economic interests in Asia

Why was the US Fighting Japan? Beginning in 1931 Japanese troops began invading parts of China and continued expanding their invasion throughout the 1930s (ie. Manchurian Crisis with weak League of Nations response) September The U.S. placed an embargo on Japan by prohibiting exports of steel, scrap iron, and aviation fuel to Japan, due to Japan's takeover of northern French Indochina.

June 1941 through the end of July Japan occupied southern Indochina. Two days later, the U.S., Britain, and the Netherlands froze Japanese assets. British PM Churchill feared that Hong Kong (British colony in the Pacific) would be next – asked Canada to send troops to help with defence The U.S. wanted to stop Japanese expansion but the American people were not willing to go to war to stop it.

Pearl Harbor Japan strikes at the heart of the American Pacific Fleet stationed at Pearl Harbor, Hawaii Prior to December 1941, Japan pursued two simultaneous courses: try to get the oil embargo lifted on terms that would still let them take the territory they wanted, and to prepare for war.

Their greatest concern was the U.S. Pacific Fleet, based in Pearl Harbor so the Japanese navy planned to cripple the Pacific Fleet by a surprise attack. The U.S. had broken the Japanese diplomatic code and knew an attack was imminent. A warning had been sent from Washington, but it arrived too late.

The Attack! On December 7th 1941 the first wave of Japanese airplanes left 6 aircraft carriers and struck Pearl Harbor a few minutes before 8 AM local time. Over the course of two hours, they killed or wounded over 3,500 Americans and sank or badly damaged 18 ships - including all 8 battleships of the Pacific Fleet At least 1,177 lives were lost when the Battleship U.S.S. Arizona exploded and subsequently sank. Both USA and Canada formally declared war on Japan following attack on Pearl Harbour; Germany declares war on the US four days later Pearl Harbor Day Attack - YouTube
