Adolf Hitler was a meth smoking idiot who could give good public presentations. He was a TERRIBLE leader with good charisma. Just my opinion.
He was a great leader (notwithstanding that he was a mass murderer). He came from obscurity and managed to get himself elected Chancellor. His party had the majority. He also eliminated enemies within his own party (got rid of Rohm and the SA leadership).
Of course he told the Germans what they wanted to hear and had their support to the last days of WW2.
