Asia & the Pacific

The world has crossed over to a new nuclear era, where a fateful error -- rather than intentional aggression -- is the most likely catalyst to nuclear catastrophe.

In the cyber arena, the same technologies that are creating unprecedented benefits for billions are also democratizing destruction. Graham Allison reviews ‘The Virtual Weapon and International Order’ by Lucas Kello.

Regardless of the innovations that lie ahead, technology by itself will neither doom nor rescue the world. Responsibility for our fate, for better or worse, will remain stubbornly human.

As Donald Trump's inauguration approaches, people around the world are struggling to understand the inhabitants of the newest Trump Tower, the one at 1600 Pennsylvania Avenue, Washington DC. With freewheeling leadership, uncertainty about the enduring guidance of presidential statements and less ideological coherence than in previous cabinets, the processes by which decisions are reached will be vital. 

Matthew Bunn, Professor of Practice at Harvard Kennedy School and Co-Principal Investigator at the Belfer Center’s Project on Managing the Atom, sits down with Aroop Mukharji (@aroopmukharji) to talk about everything nuclear—from the nuclear football to the best way to prevent nuclear smuggling.

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

Matthew Bunn, Will Tobey, Hui Zhang, and Nickolas Roth recently participated in a two-day roundtable discussion sponsored by the Stanley Foundation on U.S. nuclear security cooperation with Russia and China. The discussion, which involved experts from around the world, focused on overcoming challenges to nuclear security cooperation and ensuring that countries put in place effective and sustainable nuclear security measures with strong security culture.

Today, the United States and Japan announced that Japan would eliminate all the plutonium and highly-enriched uranium at its Fast Critical Assembly (FCA) at Tokai-mura.  This is a tremendous step forward for nuclear security; for terrorists, this would be some of the best material that exists in any non-nuclear-weapon state.  The material includes 331 kilograms of plutonium, most of it weapons-grade, and 214.5 kilograms of weapons-grade HEU.  (The FCA also includes over a ton of material just at the 20 percent U-235 mark that defines HEU.)   The weapons-grade HEU is enough for four simple terrorist “gun-type” bombs or a larger number of trickier-to-build implosion bombs.  The plutonium amounts to more than 40 bombs worth of material.

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.
