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. 

Since its creation in 1947, the Central Intelligence Agency (CIA) has been at the heart of supporting United States foreign policy and national security decision-making. From the early days of the Cold War to Russia’s war against Ukraine, the CIA has been a critical instrument of foreign intelligence collection, analysis, and operations. However, the CIA is often misunderstood, as its own work and history, particularly its successes, are rarely seen by the public. To help unpack this storied history, and in honor of the agency’s 75th anniversary, on September 16, 2022, former directors, officers, scholars, students, and the public gathered to discuss the past, present, and future of the agency. 

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 U.S. should accept with humility its inability to fully eliminate terrorism. Specifically, U.S. policy must balance “ends, ways, and means;” establish clear and achievable objectives; adopt efficient, effective, and resource-sustainable strategies; ensure synchronization of diplomatic and military efforts; build alliances to share the burden of countering terrorism; and leverage cooperative mechanisms and regional partnerships to increase the capacity and willingness of regional states to defend their sovereignty and contribute to multinational coalitions against terrorism.  A balanced, integrated, and synchronized strategy encompassing defense, diplomacy, economic, and humanitarian assistance lines of effort should be cornerstone of a revamped foreign policy in the coming decades.

The strategic competition in the Indo-Pacific involving the United States, Australia and the Chinese Communist Party (CCP) is arguably the most significant contemporary international relations issue. It spans all aspects of state power: hard, sharp and soft; diplomatic, information, military and economic; and all domains: air, sea, land, space, cyber, technology and innovation. But in their rush to recover ground perceived to be already lost to the CCP, neither the U.S. nor Australia have paused to devote sufficient attention to understanding the nature of strategic competition, to comprehend what winning it actually means, and therefore to grasp how best to approach it. As a result, they both continue to cede the initiative to the CCP, while it continues to compete on the terms most favorable to it.

The resurgence of Islamic State of Iraq and Syria (ISIS) or the next evolution of violent extremist ideology will undoubtedly flow from this region. Regional and global actors have protracted the conflict and stymied the peace process. This paper is not an exposé on the plight of Syrian refugees nor is a plea to rebuild Syria. Instead, this paper discusses the national security threat components of weaponized populations and mobile safe havens used by violent extremist organizations and offers policy recommendations to support a long-term strategy to reduce violence in the region, contain these new threats, and set conditions for reconciliation and peace.
