"The reaction by most of the media, by the Democrats, by the anti-Trump people is like mob violence. I've never seen anything like it in my life."

"This is the president of the United States, doing what every president... since FDR in 1943 with Stalin, meeting with the head of the Kremlin. And every president since Eisenhower, a Republican by the way, has met with the leader of the Kremlin for one existential purpose: To avoid war between the two nuclear superpowers. Today, in my considered, scholarly, long-time judgment, relations between the U.S. and Russia are more dangerous than they have ever — let me repeat, ever — been, including the Cuban missile crisis. I want my president to do -- I didn't vote for this president-- but I want my president to do what every other president has done. Sit with the head of the other nuclear superpower and walk back the conflicts that could lead to war, whether they be in Syria, Ukraine, in the Baltic nations, in these accusations of cyber attacks. Every president has been encouraged to do that an applauded by both parties. Not Trump. Look what they did to him today. They had a kangaroo court. They found him guilty. And then you had the former head of the U.S. CIA, who himself ought to be put under oath and asked about his role in inventing Russiagate, calling the President of the United States treasonous. What have we come to in this country? And what is going to happen in the future?"

Said NYU Russia expert Stephen F. Cohen (speaking on Tucker Carlson's show Monday).

Cohen is a contributing editor at The Nation, a left-leaning publication. In the interview, he said to  Carlson, "Let me ask you a question, you know D.C., why do these people dislike Putin, the president of post-communist Russia more than they ever seemed to dislike the communist leaders?" Carlson just repeated the question, and Cohen said "There is an answer but we'd need a lot more time and a psychiatrist."

Note: The transcript at the Real Clear Politics link was full of little errors. I watched the video (embedded there) and have corrected the text. Nothing substantive.

ADDED: In a similar vein, there's Rand Paul:

You know, I think engagement with our adversaries, conversation with our adversaries is a good idea. Even in the height of the Cold War, maybe at the lowest ebb when we were in the midst of the Cuban missile crisis, I think it was a good thing that Kennedy had a direct line to Khrushchev. I think it was a good thing that we continue to have ambassadors to Russia even when we really objected greatly to what was going on, even during Stalin’s regime.

So, I think that it is a good idea to have engagement. And I think that what is lost in this is that I think there's a bit of Trump derangement syndrome. I think there are people who hate the president so much that this could have easily been President Obama early in his first administration setting the reset button and trying to have better relations with Russia, and I think it's lost on people that they're a nuclear power. They have influence in Syria. They're in close proximity to the troops in Syria. They are close to the peninsula of North Korea and may have some influence that could help us there....
