What strategy did the Big Three adopt to fight the war?

The Big Three—the United States, the United Kingdom, and the Soviet Union—adopted a strategy of "Germany First" during World War II, prioritizing the defeat of Nazi Germany before turning full attention to Japan. They coordinated their military efforts through a series of conferences, establishing joint operations in Europe while providing support to the Soviet Union on the Eastern Front. This strategy involved a combination of direct military engagement, economic support through programs like Lend-Lease, and strategic bombings to weaken Axis powers. Ultimately, their collaboration and resource pooling were essential to achieving victory in Europe before focusing on the Pacific Theater.
