The Obama administration has proposed steep cuts in funding for improving security for dangerous nuclear materials. If approved, they would slow progress toward preventing the essential ingredients of nuclear bombs from falling into terrorist hands. Cutting too Deep reviews funding trends over the past four years and describes how the proposed cuts would delay nuclear and radiological material removal, research reactor conversion, and other work.

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.

A long-standing goal of diplomacy with Iran is persuading Iran to suspend its enrichment operations while it clarifies its past activities and while negotiations proceed on a more permanent resolution to the nuclear crisis.

The international community needs to be aware of the diversion risks during a suspension of enrichment activities and should mitigate these risks by including the necessary verification measures during negotiations and signing of any agreement on suspension.
