The USAF is arguably the only airforce in the world with a genuinely independent strategic warfare capability in the form of a large fleet of capable heavy bombers. Pretty much every other airforce in the world is basically limited to providing a striking/air-defence/logistical support package for the other two services, and could really be folded into the more senior services.

SAC ceased to exist in 1992. This is the main reason why Air Force, Inc. is not longer required as a military force. Give the ground attack stuff to the Army. Give the fighters, space stuff, and missiles to the Navy. Set up Air Mobility Command as a separate service/agency.
