Why does the world's most secure nation keep failing at its own foreign policy?

In short: Stephen Walt, a prominent realist scholar at Harvard, argues that the United States is fundamentally ill-equipped to manage global affairs. He contends that an obsession with activist intervention and exaggerated threats—rather than strategic restraint—has consistently undermined American interests, leaving the nation less secure and its international image in decline.

Stephen Walt is a leading figure in the realist school of international relations, known for developing the balance-of-threat theory. This framework modifies traditional balance-of-power concepts by accounting for aggressive intentions, geographic proximity, and offensive capabilities. Throughout his career, Walt has consistently advocated for a strategy of offshore balancing, urging the United States to intervene abroad only when absolutely necessary and to maintain a minimal military footprint.

Walt’s critique of U.S. foreign policy often centers on the influence of domestic interest groups and an entrenched establishment. His 2006 work with John Mearsheimer on the Israel lobby sparked intense global debate, arguing that a loose coalition of organizations steers U.S. policy in ways that often conflict with broader regional stability. While critics like Christopher Hitchens accused the authors of mischaracterizing the origins of modern conflicts, supporters like former ambassador Edward Peck argued that the intense backlash itself served as evidence of the lobby's significant reach.

Beyond the Middle East, Walt has challenged the consensus on American primacy. He argues that the U.S. frequently misreads minor powers like Iran or North Korea as existential threats, while ignoring the structural benefits of its own secure geography. His analysis of the war in Ukraine similarly emphasizes the risks of NATO expansion, suggesting that a neutral buffer state would have been a more prudent path. For Walt, the recurring failures of U.S. policy stem from a lack of diplomatic finesse and a persistent, costly refusal to accept the limits of American power.
