Reading has never been a strong part has it?
You'd need to be blind not to realise there is a regional conflict going on in the middle east. Saudi Arabia and Iran might be the nation face of it, but it's clearly underwritten by sunni and shia, and is spreading
Shortly before his death King Abdullah at the Gulf Cooperation Council called for the beginning of this
"I ask today that we move from a phase of cooperation to a phase of union within a single entity".
We also know from wikileaks that the Saudis had been imploring the Americans to attack Iran. Since then the Saudi's have dramatically increased their defence procurement and been actively intervening in Bahrain and Yemen. They've been actively supplying weapons into Syria that continue to prolong that conflict, with a new king who has demonstrated his willingness to take a more radical and expansionist approach.
I was careful to describe it as "some sort of sunni superstate", with the observation that it would at the very least be a "bloc that falls under their (Saudis) influence". This sets it apart from an expanded Saudi Arabia, but you clearly read straight past that bit and only saw what you wanted to see. In this regard the control structure would be similar to something like the EU (which ironically is the observation that some of the American conservative press has drawn). It wouldn't be about
take over and occupation as you seem to be implying. Germany doesn't 'take over' other European states, but you'd be hard pressed to argue that it doesn't exert considerable influence and is able to persuade subordinate partners to follow its tow. In the case of a sunni super state trade won't be the driving force, but rather conservative theology
Last month when the Saudis were quizzed about harbouring Pakistani nuclear wepaons on their soil as a bullwark aganist a pre-emptive Indian action, they only said that the two things that were non-negotiable are their security and their faith. It follows on from moves last summer

I can however actually accept your assertion that you aren't particularly in love with Saudi Arabia (it would be difficult to be). Iran is hardly a great prospect either, but it is a better prospect with both coming from particularly low medieval bases. Iran does at least have something that passes as a democracy, does permit the wearing of western clothing for instance, allows women to attend university. Now admittedly there's a hell of a long way to go, but its perhaps a couple of centuries nearer to civilisation than the uber conservative world of Saudi Arabia. The world is fluid place Clive with lots of moving parts. Locking yourself into the cold war doesn't help you
I was of course being sarcastic when I described "the evil Assad as the root cause", but I'll let you look up who made this allegation on September 27th, 2015.
"He is one of the great recruiting sergeants for Isis."
Given that he's the one fighting ISIS, it's a remarkable statement of the deluded. What does the person making it seriously suggest, he surrender? That would only bolster ISIS. Ironically, a few months later the person concerned decided to join the fight!!!
