Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

This piece is a series in the Defense, Emerging Technology, and Strategy (DETS) Program’s analysis on the war in Ukraine, including a corresponding policy brief on Ukraine’s Battlefield Technologies and Lessons for the U.S. published in July 2023. 

2023 marked eighty years since the wartime adoption of the BRUSA Agreement between Great Britain and the United States. This 1943 document codified the growing relationship between U.S. and U.K. signals intelligence organizations and included policies governing the exchange of personnel and joint regulations for handling sensitive material. Security directives and protocols aligned operational processes between the democratic governments, setting new cooperative standards for nation-states battling authoritarian regimes.

From July 11-12, 2023, NATO leaders gathered in Vilnius, Lithuania for one of the most significant NATO summits in history. This timely brief by Eric Rosenbach, Grace Jones, and Olivia Leiwant serves as a background piece on Ukraine’s history with NATO, potential future pathways for accession, and the operational impact Ukraine’s NATO membership could have on the alliance. 

Given the potential for a long war this paper offers an assessment of key economic and political factors which will help define Ukraine’s capacity to effectively resist Russian aggression, occupation, and ultimately strengthen affected sectors of society. It offers corresponding recommendations for policymakers in Washington and Europe. 

In an interconnected world, cyberattacks are becoming more frequent and sophisticated. Building resilience against this asymmetric threat is critical for countries to protect their economies, critical infrastructure, and democratic institutions. However, cyberattacks do not respect borders, and no country can address this threat alone. The strength and longevity of the transatlantic partnership between the EU and the U.S. presents a unique opportunity to address this strategic threat through international cooperation. Through an analysis of cyberwarfare in the ongoing war in Ukraine, this paper proposes policy recommendations to enhance transatlantic coordination and cooperation against current and future adversaries in a new era of strategic competition. Ultimately, a stronger transatlantic partnership is critical for protecting international democratic norms, building resilience against cyber threats, and strengthening global security and stability.

In the past, strategic surprise has often stemmed from a failure of imagination. Most intelligence failures are rooted in a lack of foresight or early warning of impending events. Blue sky thinking seeks to prevent these surprises by devoting more attention not just to known risks and likely scenarios, but also to low probability, high impact events. In an unprecedented step in forging ongoing global collaboration, 129 global experts gathered in Amman, Jordan, in December 2021. The conference was held under the auspices of Jordan’s Aqaba Process and facilitated by representatives from the Harvard Kennedy School Belfer Center’s Intelligence Project. Attendees included intelligence officers, diplomats, military officers, private sector practitioners, and academics representing 29 countries, 5 continents, and 68 government and private sector organizations. Through presentations and discussion under Chatham House Rules, the conference facilitated an open exchange of ideas on the possible next big threats from terrorism and on strategies for moving forward.

The world has grown more dangerous but also less open to arms control measures that could limit some of the dangers. What can be done? Steven E. Miller offers a tour de force overview of both dismal and hopeful trends within arms control over the past decades, in this first paper of a new HCSS series on Arms Control.

The international community, acting through the OSCE Minsk Group, has been unable to induce the leaders of Armenia and Azerbaijan to resolve the Karabakh conflict, which began in 1988 and burst into a new round of fighting in September 2020. Leaders and populations on both sides had become increasingly maximalist; any leader willing to compromise could be branded a traitor. The 2020 fighting drastically changed facts on the ground. With Turkey’s assistance, Azerbaijan recovered much of the land it lost a generation previously. But Azerbaijan was compelled to permit Russia to deploy a large peacekeeping force, something it had resisted for 25 years. While its authority is diminished, the Minsk Group can play a role going forward in restoring confidence and communication between the sides, opening borders, and ultimately leading negotiations on the future status of the region.

Harvard Kennedy School (HKS) and the German Council on Foreign Relations (DGAP) convened a strategy group of experts and former government officials from the United States and Europe over the past year to discuss the crisis in the transatlantic relationship and to propose a strategy to revive and strengthen it.
