Discuss the historical significance and consequences of World War II

What will be an ideal response?

After Germany surrendered at the end of World War I, it suffered through humiliating peace terms and economic decimation as a result of the Great Depression. In the wake of these conditions, the young ideologue Adolf Hitler rose to power. By 1933, Hitler was chancellor of Germany and the leader (in German, Führer) of the National Socialist German Workers' party (the Nazi party), which would lead Germany again into a world war. In his book Mein Kampf, Hitler exalted the totalitarian state as "the guardian of a millennial future in the face of which the wishes and the selfishness of the individual must appear as nothing and submit." "The state is a means to an end," insisted Hitler. "Its end lies in the preservation and advancement of physically and psychically homogeneous creatures." His totalitarian approach destroyed democratic institutions and led to the genocide of an estimated eleven million people in Nazi gas chambers.
The war finally ended in 1944, with the atomic bombing of two Japanese cities by America. This never-before-seen destruction shocked the world and ushered in an era of existential crisis in which people grappled with the concept of evil and the prospect of annihilation at any moment.
