“What the Israelis really need is forward basing,”
Maybe not. Overflight permission and in air refueling could be enough. Do the Saudis have KC130 air tankers?
Overflight and refueling without basing is better than nothing, but it would increase turnaround time for the planes involved and possibly require lighter weapons loads for said planes, thereby increasing risk. IMO, this may be more than a quick in-and-out.
