The Iranian aircrafts and pilots have no chance against the Americans or the Israelis in dogfights.
The problem is the SAMs, not the dogfights.
Those top Soviet SAMs can blow up a plane when it tries to bomb lets say a nuclear site.
If the SAMs are destroyed, the mission would become much safer and easier to preform as you can understand.
And therefore we would probably see something like the following IAF operation:
---June 8, 1982- The Lebanon war ("Peace for the Galilee Operation"):
The destruction of the entire Soviet-Syrian air-defence system in Lebanon within few hours without a single warplane lost; Syria with the U.S.S.R built up an overlapping network of SAMs, and the density of SAM site locations was unmatched anywhere in the world including the U.S.S.R. itself.
Also the IAF achieved in dogfights a total of 80 Syrian planes shoot-downs, without a single Israeli plane being shot down.
---If the USAF or/and the IAF make a similar operation at our present scenario, the entire mission would go with ease.
