Nuclear Issues

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.

The fourth and final Nuclear Security Summit took place in Washington DC from March 31-April 01, 2016.  Despite the initial apprehension about the summits in certain parts of the world, it has been a useful process.  With more than 50 countries represented from across the world, the summits elevated the level of awareness of nuclear security. Leaders of established nuclear states began to think about nuclear security in a new way, reducing complacency about the risks of terrorism and sabotage.  This thinking took shape in national and multilateral commitments in areas including nuclear security regulation, physical protection of nuclear materials, nuclear forensics, protection against nuclear smuggling, and insider threats and nuclear terrorism.

The 2016 Nuclear Security Summit (NSS) in Washington D.C. on 1 April issued a seven-page Action Plan in Support of the International Atomic Energy Agency (IAEA). It contains steps that the summit participants commit themselves to taking and those they “advocate” the Agency “pursue”. In endorsing this plan, 2016 Summit participants focused more detailed attention on the IAEA than those who participated in the previous four nuclear security summits.

The just-concluded fourth and final nuclear security summit saw some serious progress, but also some missed opportunities.

Fifty-plus countries are attending the 2016 Nuclear Security Summit this week in Washington, DC. Notably missing from the guest list is Iran, whose recent negotiation and implementation of a landmark nuclear deal with the P5+1 led some experts to call for more engagement and cooperation in nuclear security.

At a meeting 23 and 24 March in Belgrade, US and Russian members of the Elbe Group – retired general officers from the military and intelligence services – declared that the risk of terrorism, both conventional and nuclear, is growing.  They urged that special attention must be given to preventing Daesh, al Qaeda, and other terrorist organizations which have declared openly their desire to gain weapons of mass destruction, from obtaining them.

The history of nuclear security has been described as an example of “punctuated equilibrium” -- long periods of inaction and complacency followed by events that catalyze action. U.S. history is rife with examples where the discovery of vulnerabilities or major incidents led agencies to strengthen nuclear security requirements.

Senior Fellow William Tobey testified on March 17, 2016, before the Senate Foreign Relations Committee on "Reviewing the Administration’s Nuclear Agenda."

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.)
