Hiltler, just give your idea about the followingI would look at Hitler's impact on WWII. Would Germany have lost the war if he had not been the...

There are three separate issues raised in the question. I will try to answer each in turn.

Would Germany have lost the war if Hitler had not been the leader or would they have won?

There is no doubt that Hitler was a great Military genius, and it would have been very difficult for any other person to equal his initial successes in the World War II. However, Hitler lost the war because his war objectives of achieving a dominant position in the entire world were too ambitious and and unattainable by any person. Any person following pursuing, Hitlers objectives in World War II, would have lost the war.

Would WWII have started if not for Hitler?

One of the main planks used by Hitler to gain Political power in Germany was to set right the Humiliation and losses suffered by Germany, because of the unequal Treaty of Versailles imposed upon it after World War I. The resentment of German people against this unjust treaty would not have remained dormant for long, even without Hitler raising the Issues. However, we cannot say that expression of this resentment and the action to revers the effect of the treaty would have taken the form of World War II, without Hitler. Most certainly Hitler was no ordinary man, and it is difficult to think of another person with either the inclination or the ability of start and wage a war like World War II.

What made Hitler such a charismatic leader in the first place. For instance, why were so many people willing to follow him?

I do not think Hitler was a charismatic leader. Initial Successes of Hitler were more the result of his ability to rouse the emotions of non-Jewish German by his stand against unequal treaty forced upon Germany, and his promises of their future prosperity. For convincing people he used the tactics of arousing hatred against Jewish, and making the non Jewish Germans believe that their poor condition was result of Jewish. Thus his power flowed from his ability to convince people of his false promise of bright future. This was supported by highly manipulative and dishonest political manoeuvres to gain power. Once he gained power it was sustained only by brutal suppression of all opposition.
