Initiative on the Future of Transatlantic Relations

Understanding a changing relationship

Transatlantic relations are often said to be in perpetual crisis. They have also been subject to routine renewal. However, today and into the future, the change is deeper. The political, military, economic, and ideological structures underpinning the relationship have evolved.  In the HCSS Initiative on the Future of Transatlantic Relations, we study the history and evolution of the transatlantic relationship, looking to understand the deeper ideas and structures behind the changes in the U.S.-European relationship.

In the Initiative, we explore the political and ideological underpinnings of the foreign and defence policy that governs the transatlantic relationship. We analyse the economic relationship between Washington and Brussels, with a special focus at the EU-level on trade. On defence, we focus the lens on NATO both as an international alliance and an organisation unto itself. The aim is to understand the transatlantic relationship in the broadest possible context.

  • Frozen Battlegrounds: The Strategic Cost of Transatlantic Competition Over Greenland’s Critical Raw Materials

    Greenland’s critical raw materials are attracting global attention – but will the EU and US step up, or will China fill the void? Assistant analyst Julie Jeuken investigates EU and US bilateral engagements with Greenland, finding that both share similar goals yet fall short of Nuuk's expectations. The snapshot calls for a Greenland-centred approach to transatlantic cooperation: aligning efforts with the island’s ambitions, leveraging renewable energy in mining, and coordinating with countries already active in the sector.

  • Twilight of Atlanticism? America’s shifting approaches to Europe

    This new HCSS report by strategic analyst Davis Ellison concludes that the days of relying on the U.S. as the primary guarantor of European security may be coming to an end. The transatlantic partnership will not disappear overnight, but significant changes are underway. Europe must prepare for a future where it will play a much larger role in its own defence and security affairs.

  • Maritime Security in a Time of Renewed Interstate Competition

    The rapid intensification of geopolitical disorder and growing number of threats demand a greater role from the Royal Netherlands Navy (RNLN) and its allies. But European naval forces declined sharply after the Cold War, raising questions about the current state of Dutch and European naval capabilities. In light of the recent political and military ambitions, the RNLN will therefore face a series of difficult choices when it comes to future investments and strategy. This new HCSS report by Paul van Hooft, Davis Ellison and Frederik Mertens seeks to explore these questions, and offers a series of recommendations that may help answer them.

  • Why should Europe guard the Indo-Pacific maritime commons: Order, Access, or US hegemony?

This paper examines three distinctive objectives 1. upholding the maritime order, 2. ensure that Europe maintains access to key Asian economies, and 3. support for U.S. hegemony.

United Nations Transatlantic Relations

The politics of U.S. foreign policy

Former Canadian prime minister Pierre Trudeau once remarked that “Living next to [the U.S.] is in some ways like sleeping next to an elephant…one is affected by every twitch and grunt.” Shifts in U.S. foreign and security policy affect alliances the world over, shaping regional dynamics and driving calculations across capitals. We analyse these shifts in U.S. policies in the diplomatic, economic, and military spheres, and consider their impact on the European scene. Our transatlantic team closely monitors and investigates the executive, legislative, and judicial developments in Washington, as well engages closely with the non-government expert community to peel back the layers of decisions and the thinking that informs them.

The political-military evolution of NATO

NATO remains core to the transatlantic relationship. The alliance with the U.S. remains the organising principle for much of Europe. But NATO is also evolving and is itself navigating the growing pains of an organisation in the changing European security architecture. We explore this evolution in both the international and institutional contexts, from the high political to the military operational levels. This focus on NATO includes an emphasis on nuclear policy, the politics of defence planning, and the political economy of the alliance.

European Deterrence
Mapping US-EU Relations

Transatlanticism beyond Washington

Transatlantic relations cannot be solely reduced to the alliance with Washington. Europe’s relationship with Canada, with security issues in the Caribbean, and with South America are also important factors. From the EU-Mercosur trade agreement to the Comprehensive Economic and Trade Agreement with Canada, diversifying economic ties has become a priority on both sides of the Atlantic. As the great powers continue to pursue competition with one another, multiple alignments within and between groups of small and middle powers will only become more important. We include a broad outlook on what constitutes transatlantic affairs within the Initiative, reflecting the perspectives of Ottawa, Santiago, and everywhere in between.
