World War II - United States Involvement

For the first two years of World War II, the United States repeated its initial reaction of the first world war, attempting to stay neutral and broker peace. The nation was in the beginning of its recovery from the Great Depression, was celebrating a renewed vigor with World's Fairs in New York and San Francisco, and was not of the mindset to join the initial years of fighting. That, of course, would change. Their neutrality had always been an allied stance with the nations of Europe fighting Nazi Germany, Italy, and Japan even during the first two years of war, but without troops. When Japan attacked Pearl Harbor on December 7, 1941, the sleeping bear would awaken, forced into the fight with full mettle. They would fight the remaining five years of war in theaters around the world, from the European theater to the Pacific Ocean nations of the Orient. And the final act would succumb to use of weapons not thought possible, with a ferocity unsurpassed in warfare to that point with the dropping of two atom bombs on Japan.

    USA and World War II, 1942

    After the attack on Pearl Harbor in December of 1941, President Roosevelt began to set up a new command structure for United States forces and begin operations against the Japanese in the Pacific Theater while making plans for assisting Great Britain and the allies in North Africa and Europe. A new body, the Joint Chiefs of Staff, was formed by Admiral William D. Leahy, modeled after the British Chiefs of Staff Committee with a first meeting on February 2, 1942. They would join with their British counterparts in an agreement established during the Arcadia Conference led by Winston Churchill and President Roosevelt of one month before. A series of strategies formed; it was agreed to invade North Africa in 1942, send American bombers to England, and for the British to strengthen their presence in the Pacific Theater.

    During the Arcadia Conference, the Declaration by United Nations was agreed to by twenty-six nations. It stated that the Allies would make no separate peace with the Axis enemies and that the war would be conducted fully until victory. This document would become the basis for the establishment of the United Nations in 1945.

    Troops: USA and Philippines 13,000; Japan 75,000.
    Casualties (Killed/Wounded/Missing): USA and Philippines 1,800, plus 1,100 captured; Japan 2,100.

Eventual Allied tactical victory with Japanese abandoning their attempt to retake Guadalcanal. With victory at Battle of Midway, this series of battles is considered the turning point of the Pacific War.
