North Korea just heralded the 68th anniversary of its founding by conducting its fifth nuclear test. The initial seismic recordings were larger than previously recorded activity. This, coupled with other indicators, suggests that Pyongyang’s nuclear weapons capability is accelerating.

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.

Last fall, experts from around the world gathered to identify ways to strengthen nuclear security cooperation between the United States and Russia and the United States and China. In this Policy Brief, Nickolas Roth summarizes that conversation and provides policy recommendations based on it.

The Stanley Foundation convened a group of experts and policymakers from the United States and abroad to address these issues October 15–17, 2014, at its 55th annual Strategy for Peace Conference. The group discussed overcoming challenges to nuclear security cooperation faced by the United States, Russia, and China, and next steps in ensuring that countries put in place effective and sustainable nuclear security measures with strong security cultures. This policy memo offers highlights of the discussion and recommendations of roundtable participants.

Accelerators can eventually be substituted for nuclear research reactors for the production of medical isotopes and for neutron-based research and other applications. The use of accelerators would reduce dependence on HEU and decrease the resulting risks. The United States and other countries should work together to provide the funding and exchange of information and ideas needed to speed up the development, demonstration, and deployment of technically and economically viable accelerator technologies to substitute for research reactors.

While the United States and Russia have a responsibility to draw down their arsenals, these bilateral nuclear reductions will be increasingly difficult if other nuclear powers do not join in....[I]t is time to engage the so-called "second tier" nuclear powers, especially China. The evolution of the US-China strategic relationship can affect the next stages of international arms control, even if China does not directly participate.

A nuclear North Korea makes it crucial that all countries in Northeast Asia work hard at maintaining a stable security environment that avoids the dangers of a crisis while encouraging North Korea to adopt a nuclear strategy that retains its "no first use" pledge, a strong command and control system, and a stable nuclear weapons posture. Given its relationship with North Korea, China is best positioned to encourage DPRK leaders in these directions.

John S. Park, Stanton Nuclear Security Junior Faculty Fellow at the Massachusetts Institute of Technology and Project on Managing the Atom Associate, argues that cooperation between North Korea and Iran has been a critical—yet underexamined—enabler of North Korea's recent success. He concludes that the time has come for the United States to view the two previously independent missile programs as two sides of the same coin and recommends strategies for disrupting the procurement channels between Iran and North Korea.
