Tim Marshall is one of the world’s most successful authors on foreign affairs. He’s the writer who put the ‘geo’ into geopolitics with his multi-million selling books Prisoners of Geography and The Power of Geography. 

Marshall’s principal argument is that without geography we cannot understand the world. Geography explains why Donald Trump wants to control Greenland. Greenland is of strategic military importance given it sits in the Arctic Ocean along the shortest route for Russian intercontinental ballistic missiles or submarines to reach the United States. It is also a land mass rich in rare earth metals like lithium and tungsten which will be key in building artificial intelligence and military hardware in the coming years. 

Geography also explains why China would find it highly difficult to invade Taiwan. The Taiwan Strait is about 130 km wide at its narrowest point, which is roughly three times the distance from Dover to Calais. Any invading force would face inhospitable coastlines, unpredictable monsoons and muddy, tidal beaches. Beijing might decide in time that these are risks worth taking. But these basic and immutable facts of natural terrain still matter hugely in international affairs. 

Join Marshall as he comes to Intelligence Squared stage to celebrate the release of a new 10 year anniversary edition of Prisoners of Geography updated with new chapters on Russia’s war in Ukraine, conflicts in the Middle East and The United States and China’s battle for global supremacy.

What happens when the world’s biggest economy turns its back on global trade?

In today's episode, host Adam McCauley is joined by renowned financial journalist and economist Philip Coggan to examine the far-reaching consequences of Donald Trump’s trade war.

Drawing parallels with Churchill’s economic decisions in the early 20th century, Coggan argues Trump’s tariff measures and isolationist rhetoric argues that we are witnessing the dismantling of a global economic order that has underpinned international cooperation and prosperity since World War Two.

 and reflections on income inequality, global credibility, and economic nationalism, this is a vital conversation for anyone seeking to understand what Trump’s trade war really means for the future of the global economy.

Drawing on insights from his new book The Economic Consequences of Mr Trump, Coggan explores how Trump’s shifting economic alliances, combative stance towards China, and disregard for multilateral institutions are reshaping the global financial landscape. Together, they discuss the weakening of the Western alliance, the future of US–UK relations, and how America’s trading partners — and rivals — might respond to this new era of unpredictability.

On June 7th 1907, a ship packed with Russian Jews sets sail not to Jerusalem or New York, as many on board have dreamt, but to Texas. The man who persuades the passengers to go is David Jochelmann, Rachel Cockerell's great-grandfather. It marks the beginning of the Galveston Movement, a forgotten moment in history when 10,000 Jews fled to Texas in the lead-up to WWI. In today's episode historian and author Rachel Cockerell tells this fascinating story in conversation with James McAuley, journalist and Global Opinions contributing columnist at the Washington Post.

In August 2017, over a thousand neo-Nazis, fascists, Klan members, and neo-Confederates descended on a small southern city to protest the pending removal of a statue of Robert E. Lee.

What happened in Charlottesville—and why did so few see it coming? What does it reveal about the myths we tell ourselves about America?

In this episode, we speak with Deborah Baker, Pulitzer Prize finalist and author of Charlottesville, about the harrowing events of August 2017, when a violent far-right rally turned a quiet college town into a national flashpoint. But rather than focus solely on the extremists, Baker turns her lens on the city itself—its institutions, its history, and the people who tried to stop the violence before it began.

From clergy and activists to officials who failed to act, Baker unpacks the deeper story behind the chaos. And in a startling historical parallel, she traces the echoes of a long-buried plot from decades earlier—one with chilling similarities to what unfolded in 2017.

If ever a politician got a bum rap it’s Neville Chamberlain. He has gone down in history as the British prime minster whose policy of appeasement in the 1930s allowed the Nazis to flourish unopposed. He has never been forgiven for ceding part of Czechoslovakia to Hitler in the Munich Agreement of September 1938, and for returning home triumphantly declaring “peace for our time”. The very word “appeasement” is now synonymous with him, signifying a craven refusal to stand up to bullies and aggressors. What a contrast to Winston Churchill, the man who took over as prime minister and who has ever since been credited with restoring Britain’s backbone.

But is the standard verdict on Chamberlain a fair one? After all, memories of the slaughter of the First World War were still fresh in the minds of the British, who were desperate to avoid another conflagration. And anyway what choice did Chamberlain have in 1938? There’s a good case for arguing that the delay in hostilities engineered at Munich allowed time for military and air power to be strengthened.

The concept of government is under attack. In the United States, Donald Trump has fired tens of thousands of federal workers; ignored congressional statutes; insulted judges; and allowed Elon Musk, the world’s richest man, access to sensitive government information in a slash-and-burn campaign against the US government.

In June 2025 Michael Lewis, the renowned author of bestselling non-fiction masterpieces including Moneyball, The Big Short, Flash Boys and Liar’s Poker, came to the Intelligence Squared stage to tell the inside story of how the Trump administration is dismantling the government and how potentially disastrous the consequences for us all might be.

Drawing from his new collection of essays Who is Government? The Untold Story of Public Service, Lewis argued that we must remember the often overlooked ways government officials do work that is deeply consequential to our lives. He shared impactful stories of public service, such as the story of a coal miner devoted to making mine roofs less likely to collapse and an Internal Revenue Service agent fighting tax evasion like a character straight out of a crime thriller.
