This article reviews the motivations, strengths, and weaknesses of the Nuclear SecuritySummits (NSS), both procedurally and substantively.

Chinese President Xi Jinping addresses China’s new concept of nuclear security with four “equal emphasis” at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi’s political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China’s existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

Senior Fellow William H. Tobey evaluates the effectiveness of President Obama's policies to stem the threats of nuclear proliferation and terrorism.

This article describes the status of China’s military and civilian nuclear programs, fissile material production and associated nuclear facilities, and the Chinese nuclear experts and officials’ perspectives on the nuclear terrorism threat. It gives details of China’s nuclear security practices, attitudes, and regulations, as well as identifying areas of concern. The article recommends ways to strengthen China’s nuclear material protection, control, and accounting systems and suggests opportunities for increased international cooperation.

Once described as ‘as close as lips and teeth’, in recent years the relationship between China and North Korea has become more strained. Beijing has conflicted motivations in its policy towards Pyongyang. The threat to Beijing’s interests if North Korean nuclear weapons or materials find their way into the hands of others outweighs the danger of a regime collapse in Pyongyang.

"If nuclear power is to grow on the scale required to be a significant part of the solution to global climate disruption or scarcity of fossil fuels, major steps are needed to rebuild confidence that nuclear facilities will be safe from accidents and secure against attacks."

During the Cold War, the threat of a nuclear attack came mainly from the U.S.-Russian nuclear arsenals, writes Kevin Ryan. Today, however, the United States and Russia have been forced to adapt to a new nuclear threat—that of dedicated terrorists with money and technological access who seek to obtain and use a nuclear device.

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.
