2,800 US forces including fighter squadrons, early detection aircrafts, and air defense systems were sent to Saudi Arabia by the Pentagon to join 200 service members responding to the attack from Iran. Secretary Esper is concerned about Iranian behavior and aims to improve Saudi Arabia’s defense for the time being. The deployment of the troops is being used as a warning to Iran not to threaten American interests. The fighter aircraft deployment in particular will replace squadrons of aircrafts the US already sent earlier. While the US is not seeking involvement with Iran, it will respond to attacks if needed.
