Distressing a system in distress: global nuclear order and Russia’s war against Ukraine

| Nov. 08, 2022

While prosecuting its invasion of Ukraine, Russia has relied heavily on nuclear threats, turning the war in Ukraine into a dangerous nuclear crisis with profound implications for the global nuclear order and its two constitutive systems of nuclear deterrence and nuclear restraint. These two interconnected systems, each aiming to manage nuclear possession and reduce the risk of nuclear use, are at once complimentary and contradictory. While tensions between these systems are not new, the war in Ukraine exacerbates them in unprecedented ways. The system of nuclear deterrence seems to be proving its worth by inducing restraint on Russia and NATO, while the system of restraint is undermined by demonstrating what happens to a country not protected by nuclear deterrence. The latter lesson is particularly vivid given Ukraine’s decision to forgo a nuclear option in 1994 in exchange for security assurances from nuclear powers. Russia’s use of nuclear threats as an enabler for escalation and the specter of Russian tactical nuclear use against Ukraine goes well beyond its declared nuclear doctrine. The outcome of the war in Ukraine thus has critical importance for deciding the value of nuclear weapons in global security architecture and for resolving the conundrum between the systems of deterrence and restraint.

Biden to Putin in Geneva: There's a New Sheriff in Town.

| June 17, 2021

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

Fresh Thinking on Highly Enriched Uranium Research Reactor Conversions

| Feb. 03, 2016

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.)

All HEU Removed from Georgia, Again

| Jan. 12, 2016

In 1998, in Operation Auburn Endeavor, the U.S. government helped fly 4.3 kilograms of highly enriched uranium (HEU) and low-enriched uranium (LEU) from vulnerable facilities in war-torn Georgia to the Dounreay reprocessing plant in the United Kingdom. At the time, those in the U.S. government involved in the project, myself included, thought that was all the HEU there was in Georgia. So it was a surprise when the IAEA announced the removal of another 1.83 kilograms of HEU from Georgia – apparently now really the last of the HEU there.

Summary of Nonproliferation funding in Obama Administration’s fiscal year 2016 Budget Request

| Feb. 24, 2015

The Obama administration is proposing to boost Department of Energy nonproliferation funding to $1.94 billion—more than a $300 million increase from what Congress appropriated last year—in fiscal year 2016. But this is an increase over the very low fiscal year 2015 budget proposed by the administration and then further cut by Congress. Both Congress and the Russian government have cut back on further U.S.-funded nuclear security work in Russia, and the Obama administration has yet to develop major new initiatives that could absorb those resources.

Russia puts positive spin on nuclear security cooperation – which is good

| Jan. 23, 2015

Russia’s state nuclear corporation, Rosatom, has put out a statement on the Boston Globe story on Russia calling a halt to nearly all U.S.-Russian nuclear security cooperation.  (See Russian stories based on the statement here and here.)  The statement, in essence, tries to avoid responsibility by saying that cooperation is continuing (citing work on returning highly enriched uranium from other countries to Russia), and to blame the United States for any interruption (citing the U.S. cutoff of nuclear energy and nuclear science cooperation as part of the sanctions over Ukraine).

Rebuilding U.S.-Russian Nuclear Security Cooperation

| Jan. 22, 2015

As the Boston Globe reported Monday, Russia has put a stop, for now, to most U.S.-Russian nuclear security cooperation.  Russian, U.S., and world security will be in more danger as a result.  But some small pieces of cooperation continue – and with creativity and effort, it may be possible to rebuild a robust nuclear security dialogue of equals, rather than a donor-recipient relationship.

Belfer Experts: The End of U.S.–Russian Nuclear Security Cooperation?

Jan. 21, 2015

More than two decades of U.S.-Russian cooperation to keep potential nuclear bomb material out of terrorist hands largely came to an end last month, as The Boston Globe reported Monday. Although the dangers have not gone away, Russia is no longer interested in working on most nuclear security projects with the United States— yet another victim of increasing tension between the two countries. The Belfer Center has been centrally involved in these efforts since their inception. Belfer Center experts Graham Allison, Matthew Bunn, and William Tobey offer their thoughts.

Snapshot of Nonproliferation Budget Process for 2015

Dec. 16, 2014

Last week, the House and Senate agreed on a budget to fund the federal government—including nonproliferation and nuclear security programs—through fiscal year 2015. Despite its participation in the Nuclear Security Summit earlier in 2014 and strong rhetoric from President Obama about the need to prioritize nuclear security, his administration proposed cutting spending on programs to strengthen security for nuclear weapons useable material for the third year in a row. In response, twenty-six Senators signed a letter to the Obama administration requesting that funding for nonproliferation and nuclear security programs be increased.
