As I recall, it didn't take many IAF planes to stop the Syrian armor. And Jordan would have fallen to the PLO/Assad push without the Israeli help.
True. All the IAF had to do was conduct a flyover and that sent the Syrian packing. The PLO/Syrians were looking for an easy victory. Not long after, the Jordanians were poised to defeat the PLO and then the Soviets and the US stepped in and rescued the PLO. Very sad. The PLO could have been destroyed once and for all right there and then.
