Nuclear Issues

"There’s no track record here. Kim Jong Un hasn’t met with the Chinese leadership."

It was the debut speech heard around the world – Donald Trump at the United Nations, putting American First and other nations on notice. Over the course of 41 minutes, the president criticized the Iran nuclear deal, promised to “totally destroy” North Korea if its leader Kim Jong-Un – otherwise known as “Rocketman” – continues his path and vowed to crush the “loser terrorists” in the Middle East.

A look at North Korea's latest rounds of missile tests with David Ignatius of the Washington Post, David Sanger of The New York Times, Lionel Barber of the Financial Times, and Nicholas Burns of Harvard's John F. Kennedy School of Government.

Nick Burns tells CNBC that Trump should stick with sanctions and avoid military conflict with North Korea. "Right now there are no good military options beyond defense," he says. Burns also says the Trump administration could begin to impose secondary sanctions.

Professor Burns joins "CBS This Morning" to discuss the new U.N. economic sanctions against North Korea and China's role in the process.
