OK, I haven't seen TG2, but don't the Fs still have to keep the Migs off the A10s. If you have total air superiority, or are not especially interested in neutralizing assorted armor, just need to take out SAM and Migs so the Bs can get past them and reach the nuclear launch sites, or Qadafie's palace, I think you'd want some F-somethings nearby as somebody should probably be keeping an eye on angle sector while the A10s kind of have their arses up in the air when they are focused on pounding 6 O'c. 30mm doesn't have the range for that and drones are probably a bit too low and slow for mig chasing. When you've got nothing else to do but pound tanks, sure you want enough A10s to block out the sun.
Since failing attackers often go on to defending their homeland the die is probably a bit weighted towards victory falling to the ultimate attackers. On the other hand, are attackers ever ultimately the winners of any conflict. How many conflicts have there been between England, France, Spain, Germany, Russia, Italy. Turkey, Israel, Egypt, Syria, Scotland, Wales ... yet they all continue to exist in various forms. Unless you kill every man and child, enslave all the women and plow salt into the fields, wars accomplish little in the long term scheme of things. Most results are temporary.
A black swan to a turkey is a white swan to the butcher ... and to Boeing.
