Grand Strategy Implications of Trump’s Iran Debacle: Is This the End of Primacy?

For decades, U.S. grand strategy has been defined by the pursuit of primacy and military dominance. But costly wars—from Iraq to Afghanistan—have repeatedly raised questions about whether this approach is sustainable. Now, in the aftermath of a failed war with Iran, those questions have returned with new urgency. Has this conflict dealt a blow to U.S. power comparable to the Iraq War? Or does it mark a different kind of turning point—one that reshapes how Washington approaches both adversaries and allies? The Quincy Institute held a timely conversation on the strategic consequences of the Trump administration’s failed war with Iran—and what it means for the future of American foreign policy. This panel examined the global and regional implications of the conflict. How has the war altered the balance of power in the Middle East? What are the downstream effects for U.S. alliances and deterrence in Europe and Asia? And perhaps most importantly, does this moment create an opening to rethink U.S. strategy—moving away from militarized dominance toward a more restrained, diplomatic approach? It featured leading voices in the debate over American grand strategy —Stephen Walt, board member at the Quincy Institute, Stephen Wertheim, senior fellow in the American Statecraft Program at the Carnegie Endowment for International Peace, and Monica Toft, non-resident fellow at the Quincy Institute — this discussion explored whether the United States is at an inflection point. Trita Parsi, executive vice president of the Quincy Institute, moderated. *Download the full webinar transcript here*: https://quincyinst-2.s3.amazonaws.com...
