Roundtable

The future of the transatlantic relationship: A new era of US–Europe relations?

This in-person roundtable will explore the future of US–Europe relations.

Event date and time: 26 March 2025 — 17:00 TO 18:00 GMT

Event location: In person — Chatham House

Since taking office in January 2025, US President Donald Trump has upended transatlantic relations and threatened the foundations of the post-war security architecture.

The administration’s abrupt shifts in policy extend from withdrawing support for Ukraine to casting doubt on its commitment to longstanding security alliances. Likewise, it has injected a new antagonism into transatlantic relations, from discussion of the US acquiring Greenland, the territory of a NATO ally, to Vice President J. D. Vance’s unprecedented attack on European leaders’ values and priorities in a speech at the Munich Security Conference.

European leaders, meanwhile, are seeking new paths forward to ensure their economic and national security, including embracing new defense investments. With a new government on the way, Germany is at the center of these conversations, as it navigates longstanding fiscal and political constraints in a new transatlantic context.

Key questions include:

  • What is the outlook for the future of US security guarantees on the continent with respect to Ukraine and beyond
  • What role can Germany play in a future Euro-Atlantic security order with a possible reduced US presence?
