A key Iranian military commander warned President Trump that Iran's Revolutionary Guard is ready to fight — "finger on the trigger" — if the U.S. attacks the Islamic regime. Gen. Mohammad Pakpour delivered the defiant remarks as U.S. warships headed toward Iran amid shocking reports that Iranian security forces, including Gen. Pakpour's Revolutionary Guard, killed or executed at least 40,000 anti-regime protesters on Jan. 8 and Jan. 9 — a death toll much higher than international observers had originally feared.
