Westie,
The simple answer is there is a role for the Drones, B-1, F-16, F-15, A-10, AC-130, AH-64, and OH-58 and even the B-52 as well as organic Mortars and Big Bore Artillery.
If our brilliant military leadership and not so brilliant political leaders have limited the resources available to the Troops on the Ground to the extent they do not have full access to all of those choices then something is very wrong about that.
The War is not over until the last Ground Troop is safely on a large passenger airplane leaving the Area of Operations. Assuring their safety by overwhelming Fire Support should be maintained until that point.
The way things seem to be going in Syria, Iraq, Afghanistan, and Pakistan, Yemen, Nigeria, Mali, and Somalia, perhaps we might want to just declare Victory in the War on Terrorism and re-deploy our Forces to the Mexican Border.
We have had it proven to us repeatedly in the past month that even Three Year old Kids can enter the country illegally. What is to stop a determined Islamist Terrorist from doing the same thing?
We owe so much to our wonderfully incompetent President don't we?
