If only they had such power and influence...
The average persistance of a carrier based F14 or F18 over target in Afghanistan was 10 minutes. And that was using 70% of the available US military tanker fleet in support of our carriers!
We had far better logistical support due to closer Saudi air bases in the Persian Gulf War, for our F15s, and we could not stop the Iraqi air Force from bugging out to Iran. This was when we had standing patrols of E3A AWACS, Tankers and squadrons of F15s dedicated to the task!
Several hundred to a couple of thousand ISI/Taliban/Al-Qaeda fighters could have gotten out. A dozen Hip helicopter sorties and three C130 sorties (Which the Paks own) would have gotten out 25x12=300 and 3x100=300 for six hundred right there.
The Pakistanis had all their air defense radars up and monitoring their air space looking at both us and for Indian intruders. Once they had the pattern of our strikes. They could have timed flights into Kunduz that stayed on the ground no more than five minutes in the case of C130s and less than a minute for a Hip.
Not shooting at the Pakistanis in this situation, when we had Marine and Special Forces troops in Pakistan providing logistical support to our operations in Afghistan, doesn't constitute 'supporting' the Pakistani ISI's bug out from Kunduz. It is called preventing another Iranian style hostage crisis.
