President Wilson was quite the racist and eugenicist. I think if you do some research you'll see that he is not a very admirable figure at all.
Fascism wasn't a child of imperialism. While imperialism did promote strongman behavior in world affairs and was a horrific ideology in its own right, Nazi Germany wasn't the result of a reversion to it. Fascism was something totally new, a creation that could only be born in the 20th century. And born it was, and like imperialism has had its own effects and legacy.
There was no 'good guy' or 'bad guy' in WWI. Britain and France for example were strongmen in their own right. Germany just got shafted at Versailles and had to take the blame because they lost. Am I saying that the German Empire was better and more morally right than everyone else in respect as a strongman? No, they did plenty of bad s*** too. For example like the British and the French, they also participated in late 19th century colonialism(although Otto Von Bismark had been against it).
Hitler did use the former glory appeal, perverting and twisting that history to fit the agenda of his own. And it certainly wasn't hard with the effects of Versailles being what they were. These effects are what made his rise to power possible, without that dynamic he would've still been an art school reject. It is a common theme among fascists to appeal to some former glory of the perception thereof, and the Nazis were not unique in this respect, another example of this was Mussolini's promise to 'rebuild the Roman Empire'.
