Matthew Evangelista examines the precedents and possibilities for postwar European security in an interview with International Security Executive Editor Jacqueline L. Hazelton.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

CIPHER BRIEF INTEL REPORT — During a recent visit to Kyiv centered around The Cipher Brief’s Kyiv Economic and Security Forum, a small Cipher Brief delegation met with a variety of representatives from government, business, and civil society, who conveyed a consistent and compelling message of unity and determination to win the war that Russia started in 2014 with the invasion of Crimea, and since February 24, 2022, when it launched a full-scale invasion of Ukraine.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

Over the past quarter century, nearly all major efforts at establishing a durable post–Cold War order on the Eurasian continent have foundered on the shoals of Ukraine. For it is in Ukraine that the disconnect between triumphalist end-of-history delusions and the ongoing realities of great-power competition can be seen in its starkest form.

Recently declassified documents reveal a heated debate within the Clinton administration about how to enlarge the North Atlantic Treaty Organization to Central and Eastern Europe and when.

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.
