The aft forgotten fact of airwarfare is that you can't do a 100% intercept in BVR combat unless you already stack the advantages: AWACS/JSTAR platforms in the air that you can depend on and therefore gain an information edge, and with this better coordination defeating the enemy in detail.
The American Warmachine that's synonymous with Air Power is yet to demonstrate that it can do the same with a developed opponent.
The F22's superb capabilities only allow you to capitalize on the above, without it, even the best plane in the world will take significant casualties. Stealth can allow you to do strike missions and even first strikes, but stealth is not all powerful. A well seeded (by radar installations and airborne radars) air defense can still pick up a stealth plane if he ventures too deep into the area. A networked radar system that uses transmitted radar signal from one station to another can also greatly compromise the stealth as instead a reflected signal, they're looking for ghosts in the other radar station's signal. A ghost that was scattered by the stealth plane and hence can't be picked up by the emitting station, but can be noticed - or more properly the absence of the expected signal - by the other station.
The development of such radar systems are already in progress.
So, no stealth isn't the be all, end all answer to air strikes or air superiority. It is a significant advantage, but an well armed (and thanks to the cheaper price tag more numerous) 4th Gen. Air Force of say...China will be a tough nut to crack never the less.
