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.

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.

The current global nuclear order is extremely fragile, and the three most urgent challenges to it are North Korea, Iran, and Pakistan. If North Korea and Iran become established nuclear weapons states over the next several years, the nonproliferation regime will have been hollowed out. If Pakistan were to lose control of even one nuclear weapon that was ultimately used by terrorists, that would change the world. It would transform life in cities, shrink what are now regarded as essential civil liberties, and alter conceptions of a viable nuclear order.

Nuclear terrorism is a realistic threat to all countries. First, this article describes the potential threats of nuclear terrorism including nuclear explosives, nuclear sabotage, and dirty bombs. Finally, this article recommends steps to secure nuclear weapons, nuclear materials, and nuclear facilities.

Carter, Deutch, and Zelikow addresses the threat of Catastrophic Terrorism in Foreign Affairs.

Op-ed by Dr. Ashton B. Carter and Dr. Graham T. Allison in The Washington Post

"China is a nuclear-weapon state and rising power entering an era of particularly rapid nuclear energy growth and fuel-cycle development. China’s approach to strengthening the security of its nuclear weapons, materials, and facilities is important because of the quantity of materials involved and the role that China plays in facilitating strong global action on nuclear security..."

Since the collapse of the Soviet Union, Graham Allison, director of the Belfer Center for Science and International Affairs at Harvard Kennedy School, has consistently warned policy makers about the dangers of a nuclear weapon falling into the hands of terrorist groups such as al Qaeda. Allison spoke with the Bulletinof the Atomic Scientists about what he thinks needs to be done today to turn rhetoric about tightening nuclear security into stronger action.
