This report proposes a framework for IAEA verification of steps toward nuclear disarmament, premised on IAEA verification of fissile material, in any form, whether classified or not, submitted by any state possessing nuclear weapons. It identifies technical, legal, and financial solutions to the challenges posed by such verification, and offers a way forward to the implementation of the proposed framework. The tool that Rockwood and Shea offer is ready for any state with nuclear weapons to take up, finish the final details, and implement.

In 1996, the International Atomic Energy Agency (IAEA), the United States and the Russian Federation entered into a cooperative effort – the Trilateral Initiative – aimed at investigating the feasibility and requirements for a verification system under which the IAEA could accept and monitor nuclear warheads or nuclear warhead components pursuant to the NPT Article VI commitments of both States. Although the Initiative ended in 2002, the Model Verification Agreement produced could still serve as the basis for bilateral or multilateral agreements between the IAEA and nuclear-weapon States.

In this paper, Thomas E. Shea and Laura Rockwood examine the potential role for international verification of fissile material in relation to nuclear disarmament, what was accomplished under the Trilateral Initiative and, more importantly, what should be done now to preserve its legacy and take concrete steps towards such verification.

In trying to prevent adversaries from acquiring new military capabilities, countries often employ strategies of arms denial; e.g., “unilateral diplomacy,” supply chain interdiction, covert sabotage, and targeted military strikes. Using a game-theoretical model of weapons acquisition and denial, the authors posit that the prevalence of this approach gives rise to strategic effects that affect all players’ behavior.

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.

The U.S. achieved nonproliferation success against Taiwan in the 1970s and 1980s by forcing this highly dependent ally to accept intrusive on-site inspections that stopped its nuclear work. Taiwan depended on the U.S. for its very survival....Repeated military punishment threats against Taiwan's security (threat to abandon) and civilian nuclear program failed to change this ally's determination to acquire nuclear weapons. Success was achieved thanks to coercion by denial and dismantlement that uncovered and stopped Taipei's nuclear work.

This paper studies under what conditions the U.S. can coerce its allies to forgo nuclear weapons. Specifically, why did Taiwan and South Korea give up their nuclear pursuits under American duress, while Israel and Pakistan attained a nuclear capability?

The Belfer Center’s Eben Harrell and Pulitzer Prize-winning author David E. Hoffman for the first time report the details of one of the largest nuclear security operations of the post-Cold War years — a  secret 17-year, $150 million operation to secure plutonium in the tunnels of Degelen Mountain.
