Let's start...with the ending.
A firstpost..which is an Indian site of course, quoting "one diplomat" who mustn't be named?
NATO-style defense guarantees --->>> Come on, how long murikanns have been whining about their "expenses" in Europe, defending them?
Anything resembling that would be a death sentence for murikkans, given the region. And i don't see how they are going to get in that quagmire given how exhausted they are "defending" Europe.
Compared to snowball that is Europe where creating NATO articles is very easy by the way, West Asia is an active volcano. At this point Murikkans neither have the financial capacity or the supply chain capacity to support this. West can't really keep China out of there because of Iran-Iraq-Syria axis already exists. And Russia is already there. West couldn't do it 20 years ago when they were playing in empty field.
Keeping Palestine out of question, KSA wants this because their loads of wealth are held in usd, that's the epitome of problem. But they need to keep in mind what the consequences would be if they go ahead with this. They need to keep in mind that there exists an alternate supply chain of energy. They shouldn't overplay their hands.
