By January 1945 the Allies already know Germany and Japan will lose; the question this five-part series tracks is who wins the peace. Each episode follows the Soviet Union, Britain, and the United States as much as it follows the armies, treating Stalin, Churchill, and Roosevelt (then Truman) as characters whose personal maneuvering shapes what comes next. The first two programmes cover the closing military campaigns in Europe and the Pacific, but they run alongside the political infighting at Yalta and beyond, where the three powers start carving the postwar map into competing spheres of influence. Later episodes follow the negotiations that fix borders, occupation zones, and the balance of power that will hold for the next fifty years. Archival footage of the front lines and the conference rooms alternates with narration that keeps the chronology of 1945 clear week by week. The series argues that the real fighting that year was as much about the world after the war as the one still underway.
