Congress needs to change the doctrinal restrictions that preclude the Army from flying armed fixed-wing aircraft, send the A-10s to the Army, and the AF can wash it's hands of the CAS mission as a core mission. The Army can be like the Marines and do their own, with the AF supporting them with other aircraft as-needed and situationally. But the Army being primary responsible for their own CAS. That way, the AF can focus on air superiority, interdiction, strategic bombing/strike, space, airlift (strategic and tactical, but not all tactical), and other roles.
But alas, as much as the AF pays lip service to CAS, they don't really care for it that much, and worse, they don't want to lose the money that comes along with that mission. It's the worst case of "we don't want this toy, but it's our toy and therefore no one else can have it or play with it". Same thing the AF did with the C-27, which the Army could've and should've been operating to do their own intra-theatre light airlift, but the AF took the program, then just decided they don't want it anymore and are sending 2 year old airframes to the boneyard.
