Iran is warning that any new U.S. or Israeli escalation could trigger a far broader regional confrontation, with senior Iranian figures threatening harsher retaliation after President Donald Trump’s profanity-laced public warning. IRGC-linked messaging, comments attributed to Quds Force commander Esmail Qaani, and a direct warning from Parliament Speaker Mohammad Bagher Ghalibaf all point to the same line: Tehran wants Washington to believe that attacks on Iran’s non-military or energy infrastructure will be answered with more destructive reciprocal strikes.
