The Europeans don't want to do the great Europe. They think its great. For this reason, Europe is now suffering. Trump wants to make America great, and so how could he flirt with the enemy of America Russia?
The reason people look to Hitler as a leader is.
They are desperate and have little hope.
That won't be fixed by censorship or banning a book Hitler wrote.
The only way to fix it is to give people hope again, something to believe in.
