I understand the AF's argument that it cannot afford the luxury of mission-specific airplanes in an era of shrinking budgets, but multi-role aircraft tend to always come up short in the close support role. If history is any kind of precursor, there is always going to be the need for the close support role that can only be handled by planes that go low and slow. Look what happened in Korea: The AF had their F-80s, F-84 and F-86s, but it ended up being the prop-driven P-51 that did the heavy lifting in the close support role. Then, in Vietnam, despite having Phantoms and Super Sabres, among others, in the inventory, the Air Force had to go and acquire a (god forbid) prop-driven Navy plane, the Skyraider for the close support role. For the last 30 some odd years, the USAF finally has the right tool for the job and they keep trying to push it aside at every opportunity, only for it to make a comeback.
This is largely correct although USAF rationale isn't anti-CAS but rather pro multi-role.
The crux of the issue is that most Western air forces see their role as strategic and have never seriously structured for CAS/BAI. Multi-role aircraft allow versatility so assets can be mixed/matched to meet the overall objectives of the air campaign -- of which CAS is a small portion.
The problem, when viewed through the eyes of Big Army, is that a task-specific airframe like the A-10 will probably be available for support when called upon. A multi-role aircraft might be tasked to perform some other task within the USAF overall master air plan and (again in the eyes of Big Army) potentially not be available to provide CAS support when needed.
Risk aversion to the CAS role will rear its ugly head at some point. The Gen-5 jets are ridiculously expensive. The F-22 is north of $400M/copy and the current price of the F-35 is $175M each and carries a whopping 180 rounds of ammo for its gun.
Barring introduction of some type of light attack aircraft (AT-6?) -- which would again reintroduce a task-specific airframe -- USAF will be right back to where it is today albeit with far fewer, way more expensive jets.
