Iran has drawn a firm red line on its ballistic missile programme, declaring it non-negotiable amid renewed U.S. pressure during high-stakes diplomacy between Washington and Tel Aviv. Senior Iranian officials, including Ali Shamkhani and Foreign Minister Abbas Araghchi, warned that any attempt to impose missile restrictions would be rejected outright and could trigger a broader conflict. The warning coincided with a massive Islamic Revolution anniversary rally in Tehran, where Iran showcased an array of cruise and ballistic missiles, underscoring its deterrence posture.
