In the end the world stopped Hitler but you may mean why did the world let him start what he did at such a cost to us all. That is hard to answer, perhaps the people of the time could not conceive that anybody would be that evil - politics is sometimes very difficult and it important to learn form the past so we do not alow things to repeat. that is why learning history is so important.
No.

"For those who wish to live, let them fight, those who do not wish to fight in this world of eternal struggle, do not deserve to live." - Adolf Hitler

Hitler is a great example for why NOT to let one person have total, or near total power.

During World War 2 Hitler and Stalin maintained a keep your distance and don't tread on me attitude with one another. They both signed a phony nonaggression pact knowing Hitler would never honor it. Hitler invaded Russia and killed 20 million Russians. Stalin took his revenge out on Hitler and let his Red Army "rape, pillage and plunder" the nations they defeated Hitler's Wehrmacht army force.
Neville Chamberlain let Hitler get a bigger and stronger army and invade Poland and checkislvakia and Austria this was ageinst the Treaty of VERSAILLES

The Nazis imprisoned a great many homosexuals in concentration camps. There is no evidence that Hitler was homosexually oriented. And although Hitler hid in a closet during the Dr. Who "Let's Kill Hitler" episode, it wasn't because of his sexual orientation. He was under attack by a humanoid robot.
Hitler was a great speaker. And he was very influential. It didn't take long for the National Socialist Party to name Hitler as their leader.
