This trip may have more to do with Putin’s negotiations with Iran for their support than it has to do with Saudi Arabia.
Also, Putin may tell the Saudis that Iran is forcing him to give them nuclear weapons and delivery systems and if SA doesn’t do (fill-in-blank) he’ll be forced to do it. This visit lets Iran know that whatever fire they’re holding his feet to may not be as hot as they think it is. He has a fist full of powerful cards to play if he’s willing. Something tells me there’s no card he won’t play to get his way.
I don’t think Putin has to force any “playing cards” the Middle East is quite willing to work with Putin... and China as well. ...and the Biden Crime Family is perfectly content to let it all happen while they rake in their corrupt millions before leaving office in 2024. ...they have nothing to loose.
