Having arty, missiles, jets, and a boats (not a navy) is vastly different than knowing how to use them. I think it cosst around $30-$40K for one hour in the air for the average fighter jet (Training, maintenance, fuel, etc.). There is a lot that goes into putting a round on target as well, hence the numerous hours of continual training. As we have seen recently with the Chinese, having an aircraft carrier and being able to operate it and fly aircraft on and off of it are two different things. Ask any service member about the primacy of logistics.
Certainly ISIS having these things is bad, but how much of a threat is it really? Their ability to organize and operate on a sizable scale is low. They can terrorize, certainly, they can slowly consume equally non-competent adversaries, they can harass us when we are shackled to ridiculous rules of engagement but they clearly lack a certain amount of professionalism. How long did it take Israel to dispose of the Egyptian Air Force?
They may not care, as they have money and they just want to fly into buildings anyway. They may practice on Baghdad buildings.
The question is...who’s really funding all their high dollar toys? I’m not talking about generalities, I’m talking about specifically. We need to know our enemies by their name not just as a group.
