Robert Kagan builds on his long-standing argument that the liberal international order—once seen as a “paradise” of stability and cooperation—is increasingly under threat. Drawing from his influential works such as Of Paradise and Power and The Jungle Grows Back, Kagan explores how the US, EU, and UK are navigating a world marked by rising authoritarianism, geopolitical rivalry, and the erosion of global norms. He warns that without active leadership and strategic engagement from the West, the postwar order may give way to a more chaotic and dangerous international landscape.
