Tensions between Washington and Tehran are back in focus after Iranian lawmaker Ebrahim Azizi responded to a warning-like post from White House Deputy Chief of Staff Dan Scavino with footage of Iran's Kheibar Shekan ballistic missile. The exchange comes amid ongoing indirect U.S.-Iran contacts and renewed debate over Tehran's military capabilities. Azizi later reiterated support for regional de-escalation while defending Iran's ties with groups across the Middle East, describing them as part of a broader "Resistance Axis." The episode highlights the continuing war of signals, messaging, and deterrence between the U.S. and Iran as nuclear diplomacy remains unresolved.
