On Wednesday, October 29, the Asia Policy Program hosted Zach Cooper for a talk about the patterns behind how militaries rise and fall, and offered new insight into the future of global power. Drawing on a decade of research and his experience at the White House and the Pentagon, Cooper outlined a novel explanation for how militaries change as they rise and decline. Tides of Fortune examines the paths of six great powers of the twentieth century, tracking how national leaders adjusted their defense objectives, strategies, and investments in response to perceived shifts in relative power. All these militaries followed a common pattern, and their experiences shed new light on both China’s recent military modernization and America’s potential responses.
