Nuclear Issues

Further nuclear reduction under the current regimes seems unlikely. The US argues that Russia has violated the INF Treaty by developing and deploying a land-based cruise missile. Russia also makes the accusation that the Aegis Ashore missile defense system in Europe, capable of launching cruise missiles, has violated the INF. Furthermore, President Trump has repeatedly expressed his unwillingness to extend the New START Treaty for five more years after it expires in February 2021. The US-Russia bilateral disarmament process seems to have terminated. There have been some signs of nuclear build-up. The new US Nuclear Posture Review emphasizes the role of nuclear weapons while de-emphasizing strategic stability, reduces the threshold for nuclear use and calls for developing new low-yield SLBM and sea-launched cruise missiles. America’s nuclear policy might stimulate Russia and China to build new nuclear capabilities. North Korea’s advances in nuclear and long-range missile programs justify Washington’s investment in homeland missile defense, which in turn undermines China and Russia’s nuclear retaliatory capability and might result in a defense-offense arms race.

This study assesses current U.S. policy options on the Iranian nuclear question. It suggests that U.S. goals can be met through patient and forward-looking policymaking. Specifically, the United States can begin to lay the groundwork for an effective containment policy while continuing efforts to forestall Iranian weaponization. A successful containment policy will promote long-term positive political change in Iran while avoiding counterproductive provocation.

This chapter examines the relationship between security assurances and North Korean nuclear decision-making by focusing on four key areas: key geopolitical shocks that had a major impact on the North Korean regime; main sources of security assurances for North Korea over its history; this volume's hypotheses on security assurances based on how North Korea reacted to geopolitical shocks; and conditions under which security assurances may be most effective in dealing with North Korea in the future.

When the Soviet Union collapsed in 1991, many observers feared that terrorists and rogue states would obtain weapons of mass destruction (WMD) or knowledge about how to build them from the vast Soviet nuclear, biological, and chemical weapons complex. The United States launched a major effort to prevent former Soviet WMD experts, suddenly without salaries, from peddling their secrets. In Our Own Worst Enemy, Sharon Weiner chronicles the design, implementation, and evolution of four U.S. programs that were central to this nonproliferation policy and assesses their successes and failures.

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.

Matthew Kroenig's book, Exporting the Bomb: Technology Transfer and the Spread of Nuclear Weapons, was published by Cornell University Press. Kroenig argues that nearly every country with a nuclear weapons arsenal received substantial help at some point from a more advanced nuclear state. Understanding why states provide sensitive nuclear assistance not only adds to our knowledge of international politics but also aids in international efforts to control the spread of nuclear weapons.

The spread of nuclear weapons is one of the most significant challenges to global security in the twenty-first century. Limiting the proliferation of nuclear weapons and materials may be the key to preventing a nuclear war or a catastrophic act of nuclear terrorism. Going Nuclear offers conceptual, historical, and analytical perspectives on current problems in controlling nuclear proliferation. It includes essays that examine why countries seek nuclear weapons as well as studies of the nuclear programs of India, Pakistan, and South Africa.
