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.

"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.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.

"Without energy, there is no economy. Without climate, there is no environment. Without economy and environment, there is no material well-being, no civil society, no personal or national security. The overriding problem associated with these realities, of course, is that the world has long been getting most of the energy its economies need from fossil fuels whose emissions are imperiling the climate that its environment needs."

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."
