The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

"The United States and Pakistan recently initiated a promising series of high level talks to develop a strategic relationship between the two countries. Even in pursuit of such an expanded bilateral agenda, however, lowering the risks associated with Pakistan's nuclear weapons must stand at the top of the list of priorities."

"Keeping nuclear weapons and the difficult-to-manufacture materials needed to make them out of terrorist hands is critical to U.S. and world security — and to the future of nuclear energy as well. In the aftermath of a terrorist nuclear attack, there would be no chance of convincing governments, utilities, and publics to build nuclear reactors on the scale required for nuclear energy to make any significant contribution to coping with climate change."

"...[A] primary goal in the next decades must be to remove this risk of near global self-destruction by drastically reducing nuclear forces to a level where this outcome is not possible, but where a deterrent value is preserved — in other words, to a level of minimum deterrence. This conception was widely discussed in the early years of the nuclear era, but it drowned in the Cold War flood of weaponry. No matter how remote the risk of civilization collapse may seem now — despite its being so vivid only a few decades ago — the elimination of this risk, for this century and centuries to come, must be a primary driver for radical reductions in nuclear weapons."

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.

"The greatest threat of a loose nuke scenario stems from insiders in the nuclear establishment working with outsiders, people seeking a bomb or material to make a bomb. Nowhere in the world is this threat greater than in Pakistan."

"William Langewiesche has the reputation of being one of America's best investigative reporters. Unfortunately, he has written a very bad book on nuclear proliferation." Matthew Bunn reviews The Atomic Bazaar: The Rise of the Nuclear Poor, by William Langewiesche.

In 2006, the U.S. and Indian governments struck a deal that recognizes India as a nuclear weapons power.  Critics say Washington gave up too much too soon and at a great cost to nonproliferation efforts.  Perhaps.  But India could in time become a valuable security partner.  So despite the deal’s flaws and the uncertainties surrounding its implementation, Washington should move forward with it.

A universal Fissile Material Cut-off Treaty (FMCT), which would ban the production of fissile material (separated plutonium, highly enriched uranium (HEU), and uranium-233) for nuclear weapons, has long been seen as a key building block in nuclear disarmament and non-proliferation.
