Nuclear Issues

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

Last fall, experts from around the world gathered to identify ways to strengthen nuclear security cooperation between the United States and Russia and the United States and China. In this Policy Brief, Nickolas Roth summarizes that conversation and provides policy recommendations based on it.

The Stanley Foundation convened a group of experts and policymakers from the United States and abroad to address these issues October 15–17, 2014, at its 55th annual Strategy for Peace Conference. The group discussed overcoming challenges to nuclear security cooperation faced by the United States, Russia, and China, and next steps in ensuring that countries put in place effective and sustainable nuclear security measures with strong security cultures. This policy memo offers highlights of the discussion and recommendations of roundtable participants.

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.

The 2011 “U.S. - Russia Joint Threat Assessment” offered both specific conclusions about the nature of the threat and general observations about how it might be addressed. This report builds on that foundation and analyzes the existing framework for action, cites gaps and deficiencies, and makes specific recommendations for improvement.

Fourteen years since the Arms Control and Disarmament Agency (ACDA) was dissolved, Leon Ratz (HKS '13) explores the national security implications of the loss of America's independent arms control agency. Ratz argues that the organizational merger has weakened the federal government's decision-making and analytic capabilities when it comes to addressing critical arms control and non-proliferation challenges.

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?
