World War II transformed the United States, with wartime innovation and technology spurring an era of unparalleled prosperity. Still, new difficulties loomed. The wartime economy had to convert back to civilian production. Many veterans faced challenges. As Americans enjoyed their new prosperity, voices demanding equality and social reform grew louder. The US also embraced global responsibilities, prosecuting war criminals and establishing standards of international justice. It also wrestled with the new threat posed by the expansion of communism. Guided by the Four Freedoms, Americans looked out at a changed world, contemplating their place within it.

As early as 1942, the Allies vowed to hold Japanese and German leaders accountable for their war crimes. Stunned by the breadth of atrocities they discovered, including the mass murder of civilians and brutal treatment of prisoners of war, the Allied nations made good on their promises for justice when the war ended. In the first ever international trials of war criminals, they prosecuted thousands of German and Japanese defendants accused of crimes against peace, war crimes, and crimes against humanity.

Building on the themes in Restoring Justice and introducing the themes of the next two galleries, this theater features a film that illuminates the new position the United States held as a world “superpower” during the postwar period of 1945–1950, a status based on its vibrant economy and its monopoly on nuclear weapons. The film also connects visitors to the tensions felt at the start of the Cold War, as the threats of communism and catastrophic global warfare loomed and the survival of democracy was uncertain.

World War II created a new global role for America as the “leader of the Free World.” Wartime innovation and military production propelled the United States into an era of unparalleled economic prosperity, creating the richest society in the world. Scientific, technological, and medical advancements created new opportunities in civilian life that also sparked dramatic social change. While the 1950s seemed to be a time of calm and conformity, dramatic changes were underway, as servicemembers of color and women demanded equal rights. The changes begun by World War II reverberated for decades to come.

As a lasting legacy of World War II, Americans believe that freedom is a fundamental human right. Victory in World War II did not permanently end turmoil and conflict, however, nor did it universally safeguard freedom. The Cold War and other postwar developments proved the difficulty of upholding American ideals. The United States often had to make difficult compromises in the realm of foreign policy. As the world entered the new millennium, Americans maintained their resolve to uphold and expand freedom, and to ensure the survival of the Four Freedoms proclaimed by President Roosevelt at the dawn of World War II.

Whether serving on the Home Front or on the frontlines, American citizens fought, sacrificed, and died to preserve a free world during World War II. After the war ended, Americans continued the struggle to uphold opportunity, equality, safety, and liberty across the globe. The sacrifices of the WWII generation provide guidance and inspiration for Americans to this day. The memory of World War II continues to shape our world, inspiring the American people in their pursuit of peace, justice and freedom.
