Flyboy, the IAF operates in a very very different way than most other airforces and in particular the USAF/N. BVR that is the bread and butter of the Americans is a rare luxury in our theater of operation, at least over the front. In any real scenario of war, during day-time there will be well over 100 aircrafts within AMRAAM range. Pilots handle BVR very well when they turn on the radar, see two spots ahead and play the fire and turn back game. Not so much when they have dozens and dozens of contacts that appears and disappear with the incredible amount if interference and active EW in the air.
With the short distances and intensive EW of a small crowded front, the distances are closed to visual range VERY fast. Air defense patrols in particular do not have the luxury of playing fire and turn too long. They must engage before the attackers reach the front or long range A2G missile launch, so instead of firing BVR and turning back, they fire BVR and steam on to engage with IR/guns. The Israeli industries and IAF emphasize development and deployment of the most advanced, all aspect, super maneuverability, turbo-charged, alien technology "short" range IR missiles.
In the 1981 Lebanon war, IAF employed F-15 that were much more advanced than the Syrian Mig-23/21. Still, radar guided missiles had poor results due to new EW used by the Migs and almost all fights ended in guns/IR range. Today, the guidance systems are much more advanced, but so is EW, both self defense and dedicated ground/airborne instruments, that are a closely guarded secret. Future engagements may still end up decided by guns if the counter-measures beat the guided missiles. IAF must take this into account and so is one of the few airforces that practice intense multi-plane dogfights.
