Well it should have been preceded by a Wild Weasel mission to take out the SAM radars and launchers. The Growler mission would just be extra SAM defense. There also should have been a counter-air element to deal with the enemy fighters flying CAP.
There was enough intelligence available for the mission every fixed SAM site should have eaten a couple Tomahawks in addition to the airfield. It's also a mystery why the whole facility wasn't just leveled by some B-2s loaded with GBU-37s.
There would have been fewer dog fights but that probably would have been ok.
