Why did The Allies agree on a Europe First strategy?

The Allies agreed on a Europe First strategy primarily because they viewed Nazi Germany as the most significant and immediate threat to global security and stability. By focusing their efforts on defeating Germany first, they aimed to weaken the Axis powers' capabilities and prevent further aggression in Europe. This strategy allowed them to consolidate resources and coordinate military operations effectively, while also ensuring that the liberation of occupied countries could pave the way for a more coordinated approach to Japan in the Pacific later on.
