What does Trump's national security strategy mean for Europe, China and Middle East?

This is a special edition of Chatham House's Independent Thinking international affairs podcast, recorded at the Doha Forum 2025.  Many of the official and backroom discussions at Qatar's annual gathering of more than 5,000 world leaders, policymakers, dialogue, corporate and humanitarian organizations from 162 countries were dominated by discussions of President Donald Trump's National Security Strategy, which was released on the eve of the forum. At one of the first events in the Doha Forum, Chatham House Director Bronwen Maddox questioned US Ambassador to NATO Mathew Whitaker about it.  The podcast examines the implications for Europe, Asia, the Middle East and US foreign policy generally of the NSS document, which reinforces the Trump administration's 'America First' strategy, and contains stark language about Europe, talking about its 'economic decline' and 'the real and more stark prospect of civilizational erasure'. It also says: 'The days in which the Middle East dominated American foreign policy in both long-term planning and day-to-day execution are thankfully over.'  Joining host Bronwen Maddox in Doha were: Leslie Vinjamuri, President and Chief Executive Officer, Chicago Council on Global Affairs, and Yu Jie, a Senior Research Fellow on China in Chatham House's Asia-Pacific Programme, and Renad Mansour, a Senior Research Fellow with the Middle East and North Africa Programme.  Produced by Stephen Farrell and John Pollock.
