Not rescuing them from drowning in the blood of their victims they have killed is not a good strategy.
Obama’s use of the AF to bomb ISIS troops movements is not very effective as you need a man or men on the ground to direct the CAS to be effective. I gave 8 digit coordinates once to a set of F100’s and later to a set of F4’s. Both had to be adjusted as bombs don’t do much in a swamp or on very soft ground. Regardless of the terrain one needs to adjust TAC AIR as the enemy is not stationary during an assault.
