All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

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.

"In Bargaining on Nuclear Tests the historian Or Rabinowitz demonstrates the rare ability to engage with contemporary policy debates on nuclear proliferation and U.S. nonproliferation strategies on the one hand, and successfully utilize qualitative analytical frameworks in social science like prospect theory (19) on the other."

The article examines the strategic circumstances leading to non-aligned India's safeguard of its nuclear option during a crucial period in its proliferation trajectory, when it was one of the states closest to nuclear-weapons development, and faced US pressures to sign the Nuclear Non-Proliferation Treaty (NPT) that was being negotiated at the time.

"Our crystal ball is not clear enough to predict with confidence whether the global nuclear future will be characterized by peace and prosperity or by conflict and destruction. But we do believe that the choices made in the coming few years will be crucial in determining whether the world can have more nuclear power without more nuclear weapons dangers in the future."

"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."

Matthew Fuhrmann's article "Spreading Temptation: Proliferation and Peaceful Nuclear Cooperation Agreements," was published by in the Summer 2009 issue of International Security. In his article, Dr. Fuhrmann argues "Peaceful nuclear cooperation—the transfer of nuclear technology, materials, or know-how from one state to another for peaceful purposes—leads to the spread of nuclear weapons. With a renaissance in nuclear power on the horizon, major suppliers, including the United States, should reconsider their willingness to assist other countries in developing peaceful nuclear programs."

Why do states provide sensitive nuclear assistance to nonnuclear weapon states, contributing to the international spread of nuclear weapons? Using a new dataset on sensitive nuclear transfers, this paper analyzes the determinants of sensitive nuclear assistance. Dr. Kroenig first describes a simple logic of the differential effects of nuclear proliferation, which is used to generate hypotheses about the conditions under which states provide sensitive nuclear assistance. He then shows that the strategic characteristics of the potential nuclear suppliers are the most important determinants of sensitive nuclear assistance. Explanations that emphasize the importance of economic motivations do not find support in the data. This paper presents a new approach to the study of the spread of nuclear weapons, focusing on the supply side of nuclear proliferation.

Matthew Bunn was a guest on the NewsHour with Jim Lehrer discussing Pakistan's nuclear security.

Bunn said, in part: "I think there is a real, immediate danger, not because Pakistan's nuclear stockpiles are not well-guarded -- I think they are -- but there are huge threats in Pakistan. It is, after all, al-Qaida's world headquarters, and there are nuclear and military insiders with Islamic extremist sympathies and, in some cases, with a demonstrated record of selling sensitive nuclear technologies around the world, in the case of the A.Q. Khan black market nuclear network. So while there's a very focused nuclear security system in place, that system has to deal with very big threats."
