My gut feel - based solely on little tidbits like that and past actions/trends - is this...
The Saudis don't like the Iranians, different sects, different races, Saudis see themselves as the keepers of the faith, Iranians want that title...blah blah.
Saudis also know that if Iran does something stupid to Israel, Israel will turn Mecca and Medina into glass-topped self-lighting parking lots. The Saudis know for all their weapons bought with oil money, they couldn't stop that from happening.
Hence, being practical and viewing the preservation of their holy sights as paramount, they are willing to deal with Israel, even aide Israel. For a little entirely justifiable cooperation they get someone else to take the risks, and they get a thorn removed from their side.
Neither Israel nor Saudi is happy with this foolish Iranian weapons "deal" - neither is so naive as to think Iran will actually stop their weapons program. As they say, the enemy of my enemy is my friend - or at least ally of convenience. So I would not be surprised at all to see an Israeli strike staged through Saudi. Possibly with more than mere logistics support, I could see Saudi making a "statement" to Iran by striking some supporting targets to prove they weren't just being used by the Israelis.
BINGO
I’m wondering if Israel doesn’t already have assets deployed at the kingdom’s air bases, painted with Saudi markings.
