The Greenland crisis has damaged goodwill and trust between the US and Europe and has undermined perceptions of US reliability and trustworthiness.

Following the 2026 World Economic Forum Annual Meeting, should Europe now pursue independence and begin to decouple from the US?

In this bonus episode of Global Security Briefing, we hear from RUSI's Director-General Rachel Ellehuus as she discusses the state of the US-Greenland-Denmark discussions, and the potential lasting impact on the transatlantic relationship and NATO.

Rachel's remarks were recorded during a RUSI webinar on Friday 23 January 2026: https://my.rusi.org/resource-library-search.html?information_type=members-event-recordings

In an hour-long discussion, the panellists, including Rachel Ellehuus, the Director General of RUSI, Oana Lungescu, a RUSI Distinguished Fellow and former long-serving NATO spokesperson and Ed Arnold, Senior Research Fellow for European Security at RUSI, focus on the diplomatic, military and geopolitical fallout from the Greenland crisis for the transatlantic relationship.

Dr Eric Rudenshiold joins Neil Melvin to examine regional change, great-power competition and Washington's renewed engagement within the Caspian region.

The Caspian region is being reshaped by new political and economic dynamics as Central Asia and the South Caucasus deepen regional cooperation and navigate the competing ambitions of Russia, China and a newly engaged US. President Trump's first presidential-level C5+1 summit marks a notable shift in Washington's approach to a region long viewed as peripheral.

In this episode of Global Security Briefing, Neil Melvin is joined by Dr Eric Rudenshiold, Research Director at the Caspian Policy Center and former NSC Director for Central Asia, to assess how regional actors are adapting to changing power balances and what Washington's renewed focus could mean for future stability and connectivity.

The discussion explores:

• Emerging geopolitical and economic trends across the Caspian
• Russia's and China's evolving roles and competing integration projects
• Growing regional cooperation and expanding Caspian links
• The impact of US re-engagement and whether it signals a lasting shift

Professor John Bew joins Neil Melvin to reflect on the UK's evolving global role, strategic reviews, and how Britain can navigate an era of geopolitical upheaval.

Over the past decade, the United Kingdom has faced a rapidly transforming global environment marked by the rise of revisionist powers, economic disruption and the erosion of the post-Cold War international order. In response, successive governments have launched a series of major strategic reviews to redefine Britain's global role and national security priorities.

In this episode of Global Security Briefing, Neil Melvin speaks with Professor John Bew, former Foreign Policy Adviser to the UK Prime Minister. Professor Bew was the penholder on the last three UK national security strategies and was closely involved in the shaping of the most recent NATO Strategic Concept. Now back at King's College London, he reflects on how the UK has adapted to geopolitical change and what lies ahead for its foreign, defence and security policy.

The discussion explores:

• How the global order is shifting and what this means for the UK's strategic posture.
• Lessons from three major UK national security reviews and their evolution.
• The UK's response to Russia's aggression and its separate, complex, relationship with China.
• The future of European security and Britain's role after Brexit.
• The Indo-Pacific tilt and what it reveals about the UK's global ambitions.
• The evolving UK-US relationship and prospects for sustaining the 'Special Relationship'.
• How Britain can define influence and leadership in a more competitive, multipolar world.

Trump's revived 'America First' policy is reshaping US-Latin America ties, testing regional stability, governance and the balance between Washington, Beijing, and Moscow.

Nearly a year into his second term, President Trump has revived the 'America First' doctrine with a renewed focus on the Western Hemisphere. As Washington prioritises border security, transactional diplomacy and strategic competition with China and Russia, Latin American governments are reassessing how to navigate a more conditional and bilateral US approach.

In this episode of Global Security Briefing, Neil Melvin is joined by Dr Carlos Solar, Senior Research Fellow for Latin American Security at RUSI.

The discussion explores:

· How the Trump Administration is reshaping US engagement with Latin America.

· The effects of aid cuts, tariff threats and bilateral deals on regional governance.

· Shifts in defence and security cooperation under the new US strategy.

· How Latin American governments are responding to a tougher, more transactional Washington.

· The challenge of balancing US pressure with growing Chinese and Russian influence.
