“I think that is a pretty easy call,” Berger added, referring to the question of whether Trump could lead a call to arms.
“Where that puts him on the spectrum in between extremism and authoritarianism is a little more complicated.” Berger continued.
“I will not make the direct comparison, but if you look at somebody like Hitler, he had a very well developed extremist ideology he was advancing,” Berger added, making a direct comparison between Hitler and Trump despite saying he wasn’t doing that in the same sentence.
“It was very specific … we don’t have that with Trump.” Berger contended.
“I think history will probably end up looking at him as an authoritarian who attempted to use extremism to his advantage,” Berger concluded, adding “But there is still a lot that could happen.”
