It really doesn't matter now does it? It is a what if Kennedy had not been assassinated parlor discussion.
I will say that it is apparent that "secular" Baath Socialist ruled Syria is in this up to their neck. I suspect the Peacock Throne would have evolved in the same direction. They all take your money (foreign aid) they stab you in the back at the UN, and eventually, they fund and/or direct terror, employing their resources either in your face or or covertly, utilizing plausible deniability (when they fear consequences).
This is Islam and the Shah merely was a secularist Nazi rahter than an Islamo-Nazi. There is no exception to the rule. Egypt and Jordan take the money, stab the back of the donor, and then use the funds to militarily and politically back the utter destruction of Israel and the defeat of the West. Only out of fear do they occasionally more or less pretend not to be so motivated as their actions clearly prove. Which is not difficult because our media refuses to accuse them by re-printing their state run media which is thoroughly anti-Israeli and anti-West and consistently, virulently anti-US.
The only sources provided to Americans in the MSM of Islamic "journalism" are the islamic authored articles and sources that pay lip service to some blandly moderate impulse as in, well Hezbollah is adventurous--not consulting with the community--acting on its own--HAHAHAHAHAHAHAHAHAHAHAHAHA.
Take that Iran!!! Take that Syria!!! While the Arab street dances and cheers for every dead Irraeli.
We will either devastate Islam or Islam will devastate us. All else is parlor talk.
We will either devastate Islam or Islam will devastate us.
We will either devastate Islam or Islam will devastate us.
We will either devastate Islam or Islam will devastate us.
We will either devastate Islam or Islam will devastate us.
"It really doesn't matter now does it?"
It doesn't matter for America whether it's the fanatical shia clergy running Iran or a nationalist pro-American Pahlavi regime! That's absurd and utterly ridiculous on its face.
