[Iran's Top Security Official: If the US is Serious, It Will Send Ground Troops into Iran] Rezaei, Secretary of Iran's Supreme National Security Council, stated in an interview: "If the Americans are serious, let them send their soldiers into Iran. Why don't they come in? In war, the final decision is always made by ground troops. Why don't the airborne troops come in? Why don't the US ground troops enter Iran? Why do they just bomb from the air and then leave?"
