About

The Transatlantic Security Initiative’s mission is to contribute to a strong and resilient transatlantic relationship that is prepared to deter and defend, succeed in strategic competition, and harness emerging capabilities to address future threats and opportunities. This mission endures across changing political dynamics on both sides of the Atlantic and in the face of new and evolving threats.

TSI advances the interests and values of the United States and its transatlantic allies and partners through the Atlantic Council’s convening power, our cutting-edge research and substantive expertise, and through our extensive and influential network across the transatlantic community. We work in partnership with governments, the private sector, think tank community, academia and others. We hold expert public and private convenings, conduct research, organize study trips, and produce publications, commentary and analysis to shape and influence policy and debate on the biggest challenges facing the transatlantic relationship. Intellectual independence is a cornerstone of our work at all times.

Updating NATO’s maritime strategy

By STEVEN HORRELL, MAGNUS NORDENMAN, WALTER B. SLOCOMBE

On the eve of the 2016 Warsaw Summit, NATO faces a new and challenging security environment dominated by a revanchist Russia increasingly willing to challenge the West and turbulence and violence across the Mediterranean’s southern rim. In this new security environment, the maritime domains around Europe are potential friction zones and where these challenges increasingly […]

Brexit: What’s at stake for US security interests?

By WALTER B. SLOCOMBE

On June 23, 2016, a referendum will decide whether Britain will leave the European Union (EU) or remain a member. Britain’s departure from the EU would affect the rest of the world, because it would have implications for a broad spectrum of international concerns–very importantly, international security. For the United States, Britain remains among the […]

A US strategy for building defense and deterrence in the Baltic states

By DAMON WILSON AND MAGNUS NORDENMAN

Since the start of the Ukraine crisis, the Baltic States have come into sharp focus as a key friction zone between a much more assertive Russia on the one hand, and the United States, NATO, and the broader transatlantic community on the other. NATO and the United States have made promising first steps to better […]

Countering Russian aggression in Eastern Europe

By JONATHAN P. DUNNE

The past decade has witnessed a marked increase in Russian aggression and assertiveness. Many Eastern European nations, the Baltic States in particular, have recognized this disturbing and fundamental change in the European security environment and are responding both nationally and multilaterally. In “Countering Russian Aggression in Eastern Europe,” Jonathan P. Dunne, the Scowcroft Center’s US […]

Cyber, extended deterrence, and NATO

By Franklin D. Kramer, Robert J. Butler, and Catherine Lotrionte

Cyber is relevant in conflict as well as in lesser circumstances such as espionage and crime. This paper focuses on a conflict, both conventional and hybrid, with an adversary, such as Russia, that has advanced cyber capabilities (Tier V/VI as designated by the Defense Science Board) and includes a conflict with an improving, but less capable nation-state such as Iran.

NATO’s next consortium: Maritime patrol aircraft

By Magnus Nordenman

Airborne systems to provide MDA, and maritime patrol aircraft (MPAs) in particular, stand out among the most important and urgent maritime requirements. Maritime patrol aircraft fulfill a number of roles, from high-end Anti-Submarine Warfare and Anti-Surface Warfare (ASuW) to maritime Intelligence, Surveillance, and Reconnaissance (ISR), and search and rescue at sea. NATO members must now recapture these capabilities and invest in a robust maritime patrol aircraft fleet.

A maritime framework for the Baltic Sea region

By Franklin D. Kramer and Magnus Nordenman

An effective maritime framework would be a critical element in an integrated NATO deterrent and reassurance strategy for the Baltic Sea region, in light of hostile Russian actions and the emerging Anti-Access/Area-Denial (A2/AD) challenge in northern Europe. Such a framework would provide the Alliance the capability for sea and air control over the Baltic Sea region and, as necessary, support the requirements of reinforcement and combined capabilities including intelligence, reconnaissance and surveillance, electronic warfare, and precision engagement.

Train, hone, deter

By Matt Brand

NATO exercises play a vital role in ensuring that Alliance forces can respond to any contingency quickly and effectively. Not since the early 1990s has NATO’s exercise program drawn as much attention from NATO’s national leaders as it does now, due in large part to Russia’s increasingly aggressive misbehavior. The NATO exercise program provides the vital functions of keeping the member states’ forces interoperable by integrating new technologies into the force, practicing new doctrine, and validating units for their rotation into contingency roles, like the NATO Response Force.

Over the past decade, Russia has made nuclear weapons a predominant element of its national security strategy and military doctrine, while NATO has consciously de-emphasized its nuclear posture.

Why nuclear deterrence still matters to NATO

By Matthew Kroenig and Walter B. Slocombe

Over the past two decades, nuclear weapons have been deemphasized in NATO planning, but this should not be interpreted to mean that the Alliance has abandoned the core principle that a nuclear attack will meet a nuclear response, or that NATO will not retain the necessary means to deliver such a response. In the latest […]
