The 1940s were pivotal for the US both in international affairs and domestic affairs.

Internationally, WWII made the US a superpower.  The devastation of other countries and the US development of the atomic bomb led to a post-war era in which the US was the most powerful and important country in the world.  It also led to the Cold War.

Domestically, the 1940s represented a turn toward prosperity.  The decade began with the ending of the Great Depression.  By the end of the 1940s, the GI Bill was building the foundations of a new, more prosperous, and solidly middle class America.
