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.

When Ben Buchanan received his first computer 17 years ago, he could not have known that the technical skills he acquired would prove vital to understanding today's cybersecurity dilemma.

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.

This policy brief is based on “What Is the Cyber Offense-Defense Balance? Concepts, Causes, and Assessment,” which appears in the winter 2016/17 issue of International Security.

Does cyberspace favor the offense, as many analysts and policymakers claim? Three factors undermine any cyber offensive advantage, as demonstrated in a cost-benefit analysis of the Stuxnet operation against Iran. First, any measurement of the offense-defense balance must consider a cyber operation’s value as well as its cost to both sides. Second, organizational capabilities play a significant role in determining the balance. Third, offensive advantages decline when attackers target physical infrastructure rather than information networks.

In mid-July, as an attempted coup was taking place in Turkey, many in the United States wondered whether U.S. tactical nuclear weapons stored at the Turkish airbase, Incirlik, were adequately protected against theft. Congressional Research Service Nuclear Weapons Policy Specialist, Amy Woolf, recently published a short article describing some of the security systems surrounding those weapons.

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.

Associate Professor of Public Policy and Project on Managing the Atom Co-Principal Investigator Matthew Bunn provides a comprehensive assessment of global efforts to secure and consolidate nuclear stockpiles, and a detailed action plan for securing all nuclear materials in four years.  Securing the Bomb 2010 was commissioned by the Nuclear Threat Initiative (NTI). The full report, with additional information on the threat of nuclear terrorism, is available for download on the NTI website.
