Actually.
The Air Shield for the US and Israel always relies on the AWACS and JSTARS capabilities the US had, which come in a package of Satellite, E-3D/E-2D/RAAF E-7, E-8, combined with a ground-based control station and AEGIS on the Ocean.
If you are taking out the Saudi Ground station, the Air Force can pick it up with either Aerial Mobile Command (or TACAMO, which is a bunch of EC-130E) or the E-4s if push comes to shove

And that's before we start talking about SIGINT and IMGINT
Unless you can challenge the US in the Air and Space, you can't take out the USAF Early Warning Capability.
