Why Aren't the Saudis Acting More Strategically?

The Saudis have allied themselves with their biggest enemy. If Iran moves on Saudi Arabia or does something dramatic against Saudi Arabia, who the hell are they going to call Russia? So again, this makes no sense. Where are the guarantors at the end of the day of the Saudis not facing dire consequences? Do they think Luxembourg's going to come save them? No, it's us. This is how they act towards Biden. And by the way, we know how this story ends.
