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...
Watching it all unfold, I'm always wondering what info below our civilian radar is changing the equation. This missle story is plausible, and significant, if true...enough so that we've most likely already drawn a bead on their Star City, and Israel has also.
I'm thinking a premptive move, we checkmate the Axis of Evil in about 6 hours' time.
