Vance Floats a Sanctions Pause Without Congress as Iran's Clerical Leadership Watches

Vance flew to Zurich framing a narrow two-day mandate on the nuclear file and a Lebanon ceasefire. Tehran answered with a closed Strait of Hormuz, a named aircraft, and a public precondition before his plane landed.

Monexus reads it as a sanctions architecture being used as a tempo-setter, with the Iranian clerical response in the same hour as the operative counter-move.
