No doubt the IAF has the culmination of the best pilots in the world. One of them landed an F15 missing a wing :icon_supe
But that doesn't beat the fact that it cannot maintain a constant air war in Iran without US help. Iran is in the range of the F-15I, but they cant fly at their optimal altitude or else they will be shot down by SAMs. Of course they can do limited surgical strikes and they could refuel over Iraq, but they have no carriers to maintain an air campaign over Iran and its unsure how the Iraqi government would react to letting Israel use airbases, or might be for the US to decide. Of coures with US help it will be no problem. And as far as the actual combat, no doubt Israel would dominate.
Srry Rhen, last one :D
