US Air Force Third Air Force Commander Lt. Gen. Richard Clark.

Washington and Israel have signed an agreement which would see the US come to assist Israel with missile defense in times of war and, according to Haimovitch, “I am sure once the order comes we will find here US troops on the ground to be part of our deployment and team to defend the State of Israel.” And those US troops who would be deployed to Israel, are prepared to die for the Jewish state, Clark said.
