Eliot A. Cohen, a neoconservative who served as a top State Department official in the George W. Bush administration and was a critic of Trump’s candidacy, said in the aftermath that the Singapore summit was “just the latest manifestation” of Trump’s authoritarianism. He “has classic traits of the authoritarian leader. The one that’s always struck me most is this visceral instinct of people’s weaknesses and a corresponding desire to be seen as strong and respected and admired,” Cohen said. He added, “We’ve been very fortunate that the institutions have contained him.”
