The Europe First strategy was developed by the Allies to use majority of resources to defeat Germany before Japan. Germany was a greater threat at the time to Great Britain and was also weakening after many years of warfare. The United States was looking at a greater battle in terms of soldiers, casualties by genocide and land mass. Germany had not occupied only Great Britain and Russia at the time. If the U.S. did not step in with participation in the war on the battle grounds Germany may very well have conquered Europe entirely. This was a greater threat to the world and the allies than Japan presented at the time the decision was made. The Allies were able to defeat the Axis powers because of a few reasons. Hitler broke the treaty with Stalin and invaded Russia, making a very powerful enemy, and a multi-front war. The U.S. also committed to a total war, they had not been leaked by many years of war. German engineering and advancements were handicapped by a depression and destruction from war, which could no longer keep up with the booming industry of the U.S. where the world created jobs for many and a system of bonds to support the war. Japan was a simpler tale, two nuclear bombs were dropped in Japan and thousands perished, days later Japanese surrendered.
