UN Security Council resolution 1540 has come a long way since it was approved over a decade ago. Initially, many countries questioned the legitimacy of the Security Council “legislating” requirements for countries all over the world, and there were wide gaps in both reporting and action. Today, UNSCR 1540 is a broadly accepted part of the international landscape, only a few countries have not yet provided at least basic reporting on steps taken under the resolution, and many countries have taken action to fulfill the resolution’s requirements, ranging from enacting export control laws to strengthening security for biological pathogens.

Now that they are in office, President Donald Trump and his team must protect the nation from many threats – including from insiders. Insider threats could take many forms, such as the next Edward Snowden, who leaked hundreds of thousands of secret documents to the press, or the next Nidal Hasan, the Fort Hood mass killer.

In this episode of PolicyCast, Professor Matthew Bunn, a co-principal investigator for the Belfer Center’s project on Managing the Atom and co-editor of Insider Threats, explains how the US nuclear arsenal is managed, what the outgoing Obama administration’s $1 trillion commitment to modernization will entail, and what, if any, changes can be expected under President Trump. He also discusses the state of nuclear non-proliferation and the greatest nuclear threats the world faces today.

High-security organizations around the world face devastating threats from insiders—trusted employees with access to sensitive information, facilities, and materials. From Edward Snowden to the Fort Hood shooter to the theft of nuclear materials, the threat from insiders is on the front page and at the top of the policy agenda. Insider Threats offers detailed case studies of insider disasters across a range of different types of institutions, from biological research laboratories, to nuclear power plants, to the U.S. Army. Matthew Bunn and Scott D. Sagan outline cognitive and organizational biases that lead organizations to downplay the insider threat, and they synthesize "worst practices" from these past mistakes, offering lessons that will be valuable for any organization with high security and a lot to lose

The work of improving nuclear security is not done, though leaders are no longer meeting at the summit level. The threats of nuclear theft and terrorism remain very real. States, nuclear operating organizations, and institutions and initiatives supporting nuclear security must strive for continuous improvement in nuclear security. The alternative is dangerous decline. Achieving genuinely effective implementation of existing recommendations and commitments in five key areas could dramatically strengthen nuclear security around the world.

Sixty years ago, on 23 October 1956, an international conference at the United Nations (UN) headquarters in New York adopted the Statute of the International Atomic Energy Agency (IAEA). The document is almost as long as the UN Charter and remains the legal foundation of ‘the Agency,’ as the world nuclear organization is widely called.^[1] This H-Diplo/ISSF policy roundtable uses the anniversary as an opportunity to discuss the IAEA’s mandate and role in history and current affairs. Does the IAEA Statute, which was written in a very different context, stand up to scrutiny today? What does the answer suggest about the IAEA and institutions of global nuclear governance more generally? How can the IAEA be strengthened?

On November 7, 2016, Professor of Practice Matthew Bunn presented "A Peril and a Promise: Nuclear Challenges Facing the Next U.S. President" for the Winter Meeting of the American Nuclear Society.

The collapse of the Soviet Union in 1991 created unprecedented dangers. The crumbling empire had thousands of nuclear weapons, enough material to make tens of thousands more, and tens of thousands of experts with sensitive nuclear expertise. To overstate only slightly, Doomed to Cooperate: How American and Russian Scientists Joined Forces to Avert Some of the Greatest Post–Cold War Nuclear Dangers is a true story of scientists and engineers successfully working together to save the world.

No matter how much the world has changed since the Cold War, as other threats like terrorism and global warming have come to dominate our fears, nuclear dangers are still with us. But every day, there are ordinary people collaborating in extraordinary ways to keep the rest of us safe from them. For some, it's a family tradition.

Steve Brill’s terrific article “Are We Any Safer?” – the cover of the September Atlantic – describes both the progress and the follies of homeland security in the 15 years since the tragedy of 9/11.  Brill provides a readable (and highly opinionated) overview of vulnerabilities that have been largely fixed, areas where hundreds of billions have been wasted, and remaining gaps.
