Nuclear Issues

President Donald Trump, in unprecedented fashion, has been able to get the Chinese government to turn the screws on North Korea in hopes of getting Kim Jong Un to halt military provocations, according to a former diplomat who has advised Republican and Democratic presidents.

"The Chinese have done more under President Trump's prodding than any other American president. They signed on to the UN sanctions. There are now individual Chinese sanctions; the central bank governors instructed banks in China to wind up loans to North Korea," Nicholas Burns told CNBC on Friday. He appeared on "Squawk Box," a week before Trump embarks on a trip to Asia, which includes stops in China and South Korea.

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.

On April 2, 2015, the E.U. (speaking on behalf of the P5+1 countries) and Iran announced agreement on “key parameters” for a comprehensive agreement on Iran’s nuclear program. The E.U.-Iran Joint Statement is buttressed by unilateral facts sheets issued by the U.S. and Iran, which provide further details of the framework accord. Negotiators now turn to translating this framework accord into a final comprehensive agreement by June 30, 2015. Members of Congress and their staffs, as well as informed citizens, are now focusing on the Iranian challenge and assessing the framework accord. The Belfer Center for Science and International Affairs at the Harvard Kennedy School has prepared this Policy Brief summarizing key facts, core concepts, and major arguments for and against the current deal aimed at stopping Iran from developing nuclear weapons. The purpose of this Policy Brief is not to advocate support for or opposition to the tentative deal that has been negotiated, but rather to provide an objective, nonpartisan summary to inform Members and others in coming to their own conclusions. The team of experts who prepared this report includes Democrats, Republicans, Independents, and internationals, who have many disagreements among themselves but who agree that this Brief presents the essentials objectively.

When Lee Kuan Yew speaks, who listens? Presidents, prime ministers, chief executives, and all who care about global strategy.

Graham Allison and Robert D. Blackwill, two leading strategic thinkers, asked Lee Kuan Yew the toughest questions that matter most to thoughtful Americans weighing the challenges of the next quarter century. The result is their new book, Lee Kuan Yew: The Grand Master’s Insights on China, the United States, and the World – published today by MIT Press.

In 1985, researchers at the Harvard Kennedy School published a book called “Hawks, Doves, and Owls,” and gave it an ambitious subtitle: “An Agenda for Avoiding Nuclear War.” Those scholars gathered again at the School on Monday (May 16) for a seminar on the current challenges in avoiding nuclear war — and to marvel at just how drastically the nuclear threat has morphed in the two decades since the Cold War ended and the Soviet Union collapsed.
