Nuclear Issues

As Pakistan celebrated the 25th anniversary of its first nuclear tests last month, it also appeared to share more details than usual about its current nuclear posture. Speaking at a seminar hosted by the Institute of Strategic Studies Islamabad on May 24, retired Lt. Gen. Khalid Kidwai provided new details of Pakistan’s otherwise ambiguous nuclear doctrine. What Kidwai says matters because he is currently an advisor to the country’s National Command Authority (NCA), which controls research and development and all other policy matters concerning nuclear weapons. He’s also the former director-general of the Strategic Plans Division (SPD), which is responsible for formulating nuclear policy and strategy as well as the security of nuclear assets.

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

In The Devil Never Sleeps,  Juliette Kayyem lays the groundwork for a new “fail safely” approach to dealing with disasters. The book shares lessons on how to better prepare for that moment. Kayyem examines notable crises, like the Challenger explosion, California wildfires, and the power outage at Super Bowl XLVII, detailing the choices people made along the way and how they impacted outcomes.

Soviet and American leaders learned during the Cuban Missile Crisis of October 1962 that inadequate communication raised perilous risks and dangers in the nuclear age. The US–Soviet Hotline was created soon thereafter, in 1963, and has operated continuously ever since. It was intended to provide a quick, reliable, confidential, ever-ready communications between heads of state in the event of crisis or war.  Hotlines remain a prudent, low-cost preparation that could prove essential in the event of a crisis that seems to be slipping out of control.

South Korea's conventional counterforce and countervalue strategy is meant to hold North Korea’s nuclear weapons infrastructure, as well as its leadership, at risk independently from the United States. This strategy is often overlooked by policymakers and analysts, who are more focused on discussing Kim Jong Un’s pledges to develop new missile and nuclear capabilities and how the new administration of President Joe Biden should approach the nuclear issue. However, as we highlight in a new article in International Security, South Korea’s strategy increasingly has a determining impact on strategic stability on the Korean Peninsula and on prospects for denuclearization.

South Korea’s conventional counterforce and countervalue strategy is a manifestation of its uncertainties over the reliability of the U.S. alliance. This strategy has significant implications for strategic stability and the potential for denuclearization on the Korean Peninsula.    

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

Julius Weitzdörfer’s earliest childhood memories are the major global events of 1986—the Space Shuttle Challenger explosion and the Chernobyl disaster. Looking back, he realizes that these events must have contributed to shaping his later research interests in managing technological risks.
