Nuclear Issues

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.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

The United States and Russia are the two countries with the vast majority of the world's nuclear weapons and material. In an age of global terrorism, they share both a special responsibility in ensuring that they each employ effective nuclear security systems and an understanding of the unique challenge of securing hundreds of tons of nuclear material. For two decades, the United States and Russia lived up to this responsibility by working together to strengthen nuclear security in Russia and around the globe. That ended in 2014 when Russia halted the majority of its work on nuclear security with the United States. The negative consequences of that decision could seriously affect international security and cooperation in the nuclear realm.

The Belfer Center’s Eben Harrell and Pulitzer Prize-winning author David E. Hoffman for the first time report the details of one of the largest nuclear security operations of the post-Cold War years — a  secret 17-year, $150 million operation to secure plutonium in the tunnels of Degelen Mountain.

In the past two decades, at least two terrorist groups have made serious attempts at obtaining nuclear weapons or the nuclear material needed to make them. They won't be the last. Foiling terrorists willing to inflict unlimited damage requires the international community to prioritize the nuclear stocks that pose the greatest risks and take immediate steps to eliminate or secure them.

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.
