Can the Transatlantic Alliance Survive the Trump Presidency?

As US–European relations face renewed strain under President Trump, this episode explores what the crisis means for NATO, European security and the United Kingdom. In this episode, Neil Melvin is joined by RUSI Distinguished Fellow Sir David Lidington to discuss the growing crisis in transatlantic relations, from the Greenland dispute and uncertainty over US security commitments to the wider impact of Russia's war in Ukraine and shifting US strategy, and to assess what these changes mean for Europe's security order and the UK's strategic choices. The discussion explores: - The resilience of Europe's security order amid transatlantic tension. - The implications of the Greenland crisis for NATO and European unity. - How NATO, the EU and smaller groupings are adapting to a harsher security environment. - The future of the Ukraine war and its impact on European security. - Whether NATO and the transatlantic relationship can endure. - How the UK should position itself in a changing Euro-Atlantic landscape.
