Checkmate in Iran
Washington can’t reverse or control the consequences of losing this war. By Robert Kagan, May 10, 2026
It’s hard to think of a time when the United States suffered a total defeat in a conflict, a setback so decisive that the strategic loss could be neither repaired nor ignored. The calamitous losses suffered at Pearl Harbor, the Philippines, and throughout the Western Pacific in the first months of World War II were eventually reversed. The defeats in Vietnam and Afghanistan were costly but did not do lasting damage to America’s overall position in the world, because they were far from the main theaters of global competition. The initial failure in Iraq was mitigated by a shift in strategy that ultimately left Iraq relatively stable and unthreatening to its neighbors and kept the United States dominant in the region.
Defeat in the present confrontation with Iran will be of an entirely different character. It can neither be repaired nor ignored. There will be no return to the status quo ante, no ultimate American triumph that will undo or overcome the harm done. The Strait of Hormuz will not be “open,” as it once was. With control of the strait, Iran emerges as the key player in the region and one of the key players in the world. The roles of China and Russia, as Iran’s allies, are strengthened; the role of the United States, substantially diminished. Far from demonstrating American prowess, as supporters of the war have repeatedly claimed, the conflict has revealed an America that is unreliable and incapable of finishing what it started. That is going to set off a chain reaction around the world as friends and foes adjust to America’s failure.
