‘There is only one thing worse than fighting with allies, and that is fighting without them.’ – Winston Churchill
In a world where geopolitical alliances are fraying and tensions are rising, what can the fragile coalition that defeated Hitler teach us about the challenges facing the West today?
In September 2025 historian Tim Bouverie came to the Intelligence Squared stage to discuss his Sunday Times bestselling book Allies at War: The Politics of Defeating Hitler. In conversation with Editor of The Spectator Michael Gove, Bouverie described how Roosevelt, Churchill and Stalin overcame deep ideological differences and strategic rivalries to form a fragile but ultimately victorious alliance against Nazi Germany.
Now, with Donald Trump threatening to abandon NATO, Vladimir Putin intent on exploiting Western fissures, and democratic nations questioning their own cohesion, the lessons of WWII’s Grand Alliance have never felt more relevant.
