The wartime alliance between Josef Stalin, Winston Churchill and Franklin D Roosevelt was arguably the most important of the 20th century – and among the most fraught. Here, in conversation with Spencer Mizen, Giles Milton explores a three-way relationship that was plagued by spats, backstabbing and duplicity – yet was absolutely critical to victory over the Nazis.
