A Void in Leadership: Analyzing the Absence at the Aspen Security Forum

This week, Mark Leonard is joined by Jeremy Shapiro, ECFR’s research director and head of its US programme, and Tom Wright, senior fellow at the Brookings Institution’s Strobe Talbott Centre and former Biden administration official, for an episode recorded live at the Aspen Security Forum in Colorado.

Mark, Jeremy and Tom discuss the forum’s tense atmosphere, marked by the Trump administration’s last-minute ban on Department of Defence participation. Amid debates on AI, supply chain resilience and geopolitical competition, the episode explores America’s inward turn and its wavering Ukraine commitment. What are the implications for Europe’s security? Is the US retreating from global leadership? And can Europe adapt to a fragmented technological and economic order?

This episode was recorded on July 18th, 2025.
