The US Supreme Court ruled against President Donald Trump on his first justification for tariffs, but he says he will push them through by other means.

On this week's Independent Thinking podcast, our experts analyse why Trump is wedded to tariffs as an economic and political tool, and what effect they will have on the US and global economies.

They also discuss whether tariffs have ended globalization for good even after the Trump era ends.

Joining regular host Bronwen Maddox are Creon Butler, director of the Global Economy and Finance programme at Chatham House, and down the line from Washington, Heather Hurlburt, a consulting fellow in our US and North America Programme.

Presented by Bronwen Maddox. Produced by Sara Seth and Stephen Farrell.

Negotiations to end the Russia-Ukraine war do not appear to have made significant progress. In the meantime, the focus of US President Donald Trump's 'lighthouse diplomacy' appears to have switched to Iran.

Chatham House analysts discuss the state of the talks, and whether Europe will step up to provide the weapons and military support that Ukraine needs. They also examine how the Russia-Ukraine conflict fits into the wider superpower competition between the US, Russia and China.

Joining host Bronwen Maddox are Grégoire Roos, director of Chatham House's Europe, Russia and Eurasia programmes; Orysia Lutsevych, head of the Ukraine Forum; and Natalie Sabanadze, Senior Research Fellow with the Russia and Eurasia Programme.

This episode comes as we look ahead to two major upcoming Chatham House events: a conversation with General Valerii Zaluzhnyi, Ukraine's ambassador to the UK, marking four years since Russia's full-scale invasion, and our annual Security and Defence conference.

Both events are now fully booked for in-person attendance, but audiences will be able to watch General Zaluzhnyi's appearance and some of the defence conference events online.

In a special edition of Chatham House's Independent Thinking podcast recorded at the Munich Security Conference 2026 over the weekend, Chatham House Director Bronwen Maddox and Grégoire Roos, Director of the Europe and Russia and Eurasia Programmes, unpack the key issues that emerged from this year's forum.

The main speaker, US Secretary of State Marco Rubio, adopted a different tone from Vice President JD Vance, who shocked many in the audience last year when he delivered a verbal broadside against Europe at the same conference.

But does it signify a shift in the Trump administration's newly assertive stance, or was it the same message in a different wrapping?

In a recording session in a side room amid the hustle and flow of the conference, they also discuss innovations in defence technology and drone development, the resilience of Ukrainian President Volodymyr Zelenskyy, what level of support Ukraine can expect from Europe, and whether European companies and policymakers will respond effectively in the face of increasing competition from Chinese manufacturers.

As Britain's Prime Minister Keir Starmer ploughs through crisis after crisis, his Labour Party faces multiple threats in upcoming local elections.

Host Bronwen Maddox is joined by Olivia O'Sullivan, Director of the UK in the World Programme at Chatham House and Grégoire Roos, Director of the Europe and Russia and Eurasia Programmes.

Chatham House Director Bronwen Maddox joins the Independent Thinking podcast from the World Economic Forum in Davos. In London are guest host David Lubin, a Senior Research Fellow in Chatham House's Global Economy and Finance Programme; and Grégoire Roos, Director of the Europe and Russia and Eurasia Programmes.

They examine the implications of President Trump's speech for Greenland, NATO, Europe, China and others after Trump pulled back from using force in Greenland, but left allies with a loss of trust in US intentions. Our analysts also discuss the impact of the address by Canadian Prime Minister Mark Carney, a former President of Chatham House, who laid out his alternative vision for middle powers to cooperate when faced with what he called 'a rupture' in the world order.
