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.

"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."

Many accounts suggest that the United States did little to prevent Israel, Pakistan, and South Africa from developing nuclear weapons. These accounts are flawed, however. The United States did attempt to stop all three countries from acquiring the bomb and, when those efforts failed, to halt additional proliferation measures such as further testing and weaponization.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

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.

Through structured interviews and a literature review, we assess which approaches to protection against insider thefts in the casino and pharmaceutical industries could be usefully applied to strengthen protections against insider theft in the nuclear industry, where insider thefts could have very high consequences.

"Nuclear proliferation is a crime that pays well. Those involved in the Khan network were made very wealthy for their efforts, and the inability of the international community to effectively punish them has resulted in a missed opportunity to provide a deterrent against future black-market salesmen."

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 Soviet strategic modernization program of the 1970s was one of the most consequential developments of the Cold War. Deployment of new intercontinental ballistic missiles and the dramatic increase in the number of strategic warheads in the Soviet arsenal created a sense of vulnerability in the United States that was, to a large degree, responsible for the U.S. military buildup of the late 1970s and early 1980s and the escalation of Cold War tensions during that period. U.S. assessments concluded that the Soviet Union was seeking to achieve a capability to fight and win a nuclear war. Estimates of missile accu¬racy and silo hardness provided by the U.S. intelligence community led many in the United States to conclude that the Soviet Union was building a strategic missile force capable of destroying most U.S. missiles in a counterforce strike and of surviving a subsequent nuclear exchange. Soviet archival documents that have recently become available demonstrate that this conclusion was wrong. The U.S. estimates substantially overestimated the accuracy of the Soviet Union's missiles and the degree of silo reinforcement. As the data demonstrate, the Soviet missile force did not have the capability to launch a successful first strike. Moreover, the data strongly suggest that the Soviet Union never attempted to acquire a first-strike capability, concentrating instead on strategies based on retaliation.
