Donald Trump's win has left many shocked - and concerned - about the future of the United States, and the world.
But what can we expect from a Trump presidency?
"The real question before us now is: Does he govern the way he ran for the presidency?" says Robert Hormats, who served as US under-secretary of state. "If he does, then we have major troubles ahead for us domestically and internationally."
"I don't think this is going to go well for the country," says investigative journalist David Cay Johnston, author of The Making of Donald Trump. "Trump could have me swept off the streets … held incommunicado."
"We have something called clause 1021 in a bill that was passed in 2012 [under Obama's presidency] that allows this guy to hold any American indefinitely without charge or trial," says Naomi Wolf, a former political adviser to former President Bill Clinton and Al Gore. "I'm extremely troubled and frightened as an American, as someone who cares about democracy."
"I can tell you - chapter and verse - since 9/11, I have not seen New York so frightened," says Hamid Dabashi, the Hagop Kevorkian Professor at Columbia University.
In this extended Arena, Robert Hormats, David Cay Johnston, Naomi Wolf and Hamid Dabashi debate the future of Trump's administration.
