May the American Military temporarily halts its search and rescue mission for the downed missing F15 pilot.
That an F15 can be shot down in that area would mean that there are still rogue IRGC active air defense systems in operation there - with radar and surface to air missiles. To send a search and rescue team would be suicidal and suffer more casualties.
Thus it would need the terrorist IRGC air defense system in that sector to be Found and WIPED OUT, before any further search and rescue operations can be conducted.
