OF HAWKS AND DOVES

The policies toward countries aspiring to acquire nuclear weapons continue to be heavily contested, differing even among countries that consider nuclear proliferation as one of the main threats to international security. This article maps the actual policies of liberal democracies toward Iran and North Korea along a continuum from confrontation to accommodation. Using data from an expert survey, the authors outline four main findings. First, policies toward both Iran and North Korea have become increasingly confrontational over time. Second, no policy convergence was observed among the states studied; that is, notwithstanding the adoption of joint sanctions, differences remained between states preferring confrontation and those opting for accommodation. Third, states maintained remarkably stable policy profiles over time. Finally, despite obvious differences between the norm violations of North Korea and Iran, states generally followed remarkably similar policies toward both countries. The authors’ findings indicate that states exhibit stable preferences for either confrontation or accommodation toward nuclear aspirants. Although a comprehensive examination of the causes of these policy differences is beyond the scope of this article, the authors present evidence that a major cleavage exists between members and non-members of the Non-Aligned Movement, indicating that the degree to which nuclear aspirants’ sovereignty should be respected is a main issue of contention.

The Moral Dimension of “Global Zero”

Regrettably, moral arguments are largely absent from the current debate on nuclear disarmament. Indeed, complementing politico-strategic thinking with ethical categories could significantly strengthen the abolitionist call. To fill the gap, this article analyzes the evolution of the nuclear ethics of the Roman Catholic Church and especially its position on nuclear deterrence. If this strategy was granted interim and strictly conditioned moral acceptance during the Cold War, nuclear deterrence is today increasingly considered ineffective, an obstacle to genuine disarmament, and hence morally unjustifiable. In the new security context, the conditions for the Catholic Church's “interim nuclear ethics” have altered, and nuclear disarmament has become a feasible option and an alternative strategy to deterrence.

The Chinese and Asian impact on Russian nuclear policy

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe.

ACQUIRING FOREIGN NUCLEAR ASSISTANCE IN THE MIDDLE EAST

The United Arab Emirates (UAE) has laid out an ambitious plan to become the first Arab country to possess a civilian nuclear energy program. Central to that effort has been the Emirati government's ability to obtain foreign nuclear assistance. This article traces the UAE's strategies for overcoming the obstacles that stood in the way of nuclear suppliers providing assistance. It examines the approach taken by the UAE to assuage the safety and security concerns of nuclear suppliers, how the UAE leveraged its alliances with France and the United States to obtain their cooperation, and its strategies for engaging domestic interest groups in supplier states. The generalizable elements of the UAE's strategies are discussed and used to provide insight into the prospects for other Middle Eastern states' bids to obtain similar assistance. The article concludes with a discussion of the potentially transformative aspects of the strategies employed by the UAE in shaping other countries' pursuit of nuclear energy in the region.     

TURKEY'S NUCLEAR COMEBACK

As worries have grown about global warming and the sustainability and price of fossil fuels, the demand for nuclear energy has increased, and nuclear power is increasingly viewed as a reliable and clean resource. However, the so-called nuclear renaissance coincides with an international security environment in which the norms of nuclear nonproliferation seem to be eroding. Turkey, a non-nuclear weapon state, plans to generate nuclear power to meet future energy demands, but it is aware of and concerned with regional proliferation trends. Questions have also been raised regarding Ankara's rationale for using nuclear energy, as well as its potential motivations and capabilities regarding future proliferation. This article will provide an overview of Turkey's nuclear energy history and plans, as well as the proliferation-related questions that could arise; it will also look at the domestic debate on nuclear energy and Turkey's status as a non-nuclear weapon state.     

INTEGRATING NUCLEAR WEAPONS STOCKPILE MANAGEMENT AND NUCLEAR ARMS CONTROL OBJECTIVES TO ENABLE SIGNIFICANT STOCKPILE REDUCTIONS

In his 2009 Prague speech and the 2010 Nuclear Posture Review, President Barack Obama committed the United States to take concrete steps toward nuclear disarmament while maintaining a safe, secure, and effective nuclear deterrent. There is an inherent tension between these two goals that is best addressed through improved integration of nuclear weapons objectives with nuclear arms control objectives. This article reviews historical examples of the interaction between the two sets of objectives, develops a framework for analyzing opportunities for future integration, and suggests specific ideas that could benefit the nuclear weapons enterprise as it undergoes transformation and that could make the future enterprise compatible with a variety of arms control futures.
