I remember Reagan and the AWACs sale, was aware of the Saudi arms buildup, but never knew jack-squat about their missile program.
I agree with you. The Saudis have grand delusions, and are likely to act upon them
OTOH, a few years back I worked at the US defense contractor which set up the Saudi air defense system, and got a good look at the "perfumed princes" that the Saudis have in their officer corps. I'm happiest at the thought that they would be on the OTHER side...
