Nuclear Issues

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

Not only would sanctioning SWIFT be a major escalation in U.S. sanctions policy, but an entirely reckless decision. Realistically, enforcing sanctions against SWIFT would have significant consequences for both the U.S. and global financial system—upending decades of international norms.

Although it remains to be seen whether or not the Iran nuclear deal is salvageable, there are few incentives left for Iran to implement anti-money laundering reforms. For better or worse, the Financial Action Task Force and the future of the JCPOA have become politically intertwined as a consequence of US unilateral sanctions.

With the world focused on the United States and North Korea, it’s easy to forget that every president for a quarter-century has said preventing nuclear terrorism was a national security priority. This includes the Trump administration, which identified in its Nuclear Posture Review that nuclear terrorism is one of “the most significant threats to the security of the United States.” It appears, however, despite this strong rhetoric, the administration may not be putting its money where its mouth is.

The escalating threats between North Korea and the United States make it easy to forget the “nuclear nightmare,” as former US Secretary of Defense William J. Perry put it, that could result even from the use of just a single terrorist nuclear bomb in the heart of a major city.

At the risk of repeating the vast literature on the tragedies of Hiroshima and Nagasaki—and the substantial literature surrounding nuclear tests and simulations since then—we attempt to spell out here the likely consequences of the explosion of a single terrorist nuclear bomb on a major city, and its subsequent ripple effects on the rest of the planet. Depending on where and when it was detonated, the blast, fire, initial radiation, and long-term radioactive fallout from such a bomb could leave the heart of a major city a smoldering radioactive ruin, killing tens or hundreds of thousands of people and wounding hundreds of thousands more. Vast areas would have to be evacuated and might be uninhabitable for years. Economic, political, and social aftershocks would ripple throughout the world. A single terrorist nuclear bomb would change history. The country attacked—and the world—would never be the same.

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.

The Summer 2011 issue of the Belfer Center newsletter features analysis and advice by Belfer Center scholars regarding the historic upheavals in the Middle East and the disastrous consequences of the earthquake and tsunami in Japan. The Center’s new Geopolitics of Energy project is also highlighted, along with efforts by the Project on Managing the Atom to strengthen nuclear export rules.

The Spring 2011 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.
