The main goal of the Allied leaders during the Second World War was to conquer the Axis power (which was headed by Adolf Hitler) and promote world peace. The goal was born as a reaction to the offensive and unprovoked attack upon the world by the Axis power. The Allied countries which include the United States, Great Britain, Soviet Union, and China came together and resolved to strategize on how to defeat the Axis power.
The strategy adopted by Allied leaders in achieving the goal of defeating the Axis power was to restructure her military in such a way that a military technique known as Leapfrogging (which involved isolating the stronghold of the Axis military while taking proactive steps to vanquish and take over strategically important territories controlled by the Axis power) was adopted and implemented.
