America at War Again. What the Iran War Reveals About U.S. Global Leadership

The U.S.-Iran war has become the most consequential American military engagement in the Middle East since the 2003 Iraq invasion. Despite periodic ceasefires and diplomatic efforts, the conflict has revealed that 21st-century power is not determined by military dominance alone. The United States has demonstrated unmatched force-projection capabilities, severely degrading Iran’s conventional forces, yet battlefield success has not produced a durable political settlement or fundamentally altered Tehran’s strategy. Instead, the conflict has settled into a cycle of coercion, adaptation, economic pressure, proxy warfare, and renewed confrontation.
