Princeton professor and Russian expert Stephen Cohen went on Anderson Cooper with unhinged #NeverTrumper Max Boot earlier this week.

The discussion quickly escalated when Max Boot accused Cohen of being a Russian sympathizer because he would not cheer on war with Russia.

Professor Cohen destroyed him.

Stephen Cohen: I have no idea what is talking about. He wants Trump to threaten Russia? Why would be threaten Russia?

Max Boot: (hysterically) Because they’re attacking us!

Stephen Cohen: I’ve been studying Russia for 45 years…

Max Boot: And you’ve been consistently an apoligist for Russia in those 45 years.

Stephen Cohen: I don’t d defamation of people. I do serious analysis of serious national security problems. When people like you call people like me, and people more eminent than me, apologists for Russia you are criminalizing diplomacy and detente and you are the threat to American national security. End of story. Why do you have to defame someone you don’t agree with? They used to do that in the old Soviet Union. We don’t do that here… This kind of hyperbole, this “attack on America” suggests we need to attack Russia!
