Rising global tensions and ideological divides are making the echoes of the 20th century louder. Odd Arne Westad, a leading historian from Yale University, studies these dynamics. In addition to his Bancroft Prize-winning book, The Global Cold War: Third World Interventions and the Making of Our Times, he also specializes in China with works like Restless Empire: China and the World and The Great Transformation: China's Road from Revolution to Reform. His work helps us understand the complex world order by connecting the past and present. As we face these familiar challenges, are we truly learning from history, or are we destined to repeat it?
