Nuclear Issues

The major global nuclear powers are building up their arsenals once again, sparking fears of a new nuclear arms race. How serious is the danger? We ask Matthew Bunn, former White House adviser on Science and Technology Policy and co-principal investigator from the Belfer Centre on Managing the Atom.

Last week, a National Academies of Sciences, Engineering, and Medicine panel affirmed the goal of eliminating highly enriched uranium (HEU) from civilian use, while recommending step-wise conversion of high performance research reactors using weapon-grade uranium fuel and that the White House coordinate a 50-year national roadmap for neutron-based research. (Full disclosure:  I sat on that committee, and oversaw the NNSA reactor conversion program from 2006-9; this post, however, represents my views, not necessarily those of the committee or NNSA.)

What can the United States do to thwart the nuclear ambitions of its allies? Dr. Kogan analyzes past cases where the United States was able to leverage its alliance commitments to stop friendly states from going nuclear. He then asks what lessons these past nuclear negotiations hold for today.  In the coming decade, key U.S. allies in the Middle East (Saudi Arabia) and East Asia (South Korea, Japan) may consider reducing their reliance on U.S. security guarantees by acquiring independent nuclear deterrents.  In conversation with Project Director Kevin Ryan, Dr. Kogan discusses Washington's options in confronting these contemporary allies with nascent nuclear appetites.

When the Cold War ended, much of the world seemed to breathe a momentary sigh of relief. The greatest existential threat in human history, that of an all-out nuclear holocaust, appeared to have practically vanished overnight. Soon it became clear that we were not quite out of the woods yet. State-versus-state tensions between the United States and Russia did not completely dissipate. New nuclear powers, like Pakistan and North Korea, emerged publicly, and suspicions about potential future nuclear powers abound. The threat of nuclear terrorism, something which had been discussed publicly since the late 1960s, took on a new relevance in the face of threats about loose fissile material and extremist terrorism.  And the global effects of even a regional nuclear exchange, such as one in South Asia, became more acutely appreciated.

Kim Jong-eun's New Year's Day address signaled a willingness to ease tensions with South Korea and focus on economic development, but how credible is this message? Project on Managing the Atom Associate and MIT Stanton Nuclear Security Junior Faculty Fellow John Park analyzes the address in an HKS PolicyCast.

Rolf Mowatt-Larssen, a former director of intelligence and counterintelligence at the Department of Energy, argues that despite not falling victim to a major terrorist event in the last 10 years, the United States must not be complacent in its counter-terrorism efforts. Mowatt-Larssen said in a Belfer Center seminar in September that he believes the possibility of a major attack is higher in the next 10 years than in the preceding decade.
