If the U.S. strikes Syria, it will in all likelihood trigger a war that will quickly spread throughout the Middle East from Israel through Saudi Arabia to Iran

If likely, why the Saudi interest?

I don't think a strike would kick off such an action, but they are probably either referring to the Saudis fighting a proxy war with Iran in Iraq and Syria, or the Saudis facing a long-term "insurgency", for lack of a better word, on their own turf. There are a lot of radicals in Saudi Arabia who would like to see the royalty overthrown.
