Anti-ship missiles arcing off the Iranian coastline, U.S. interceptors tearing upward to meet them, electronic warfare systems straining to blind hostile radars—each move calculated in seconds, yet carrying consequences that could last for years. That no U.S. ship was reportedly struck does little to soften the gravity of a moment when the unspoken rules were tested so openly.
