what was the leading reason why the world war 2 still took place? explain.?

Answer 1

There is no single leading reason, to be honest. As with most wars, WWII was the result of several conditions working together.

To attempt to provide an answer, though, I would suggest that the Treaty of Versailles after WWI created the conditions which made the war possible. By essentially making once-proud Germany a third-world country, the Treaty provided an environment in which Hitler's ultra-nationalism could thrive. The humilation of Germany, which was exacerbated by the Depression, created an atomosphere of poverty and cynicism which Hitler manipulated with promises of glory and conquest.

If Germany had been cultivated as an ally after WWI (as it was after WWII), it is unlikely that Hitler would ever have been a serious political candidate.

Answer 2

world war 2 was essentially a continuation of world war one. after ww1, germany was plunged into severe depression and had been humiliated by being heavily restricted, especially with its military. the situation allowed for hitler and his nazi party to gain political holdings by grabbing onto ideas from fringe parties that proved popular among the suffering germans. because of the extent of damage and death caused by ww1, other european leaders, such as neville chamberlain of the uk, were eager to prevent another war, so rather than challenge hitler, they appeased him, which gave credence to him as a force when he was under hindenburg's control. when hindenburg died, hitler was no longer held back.
