As a matter of fact, KSA has improved relations with Iran. The days of complete devotion to US agenda of 9/11, and middle east/oil destabilization starting with Iraq war are over. That KSA was on board with demonization of Iran, was a practical evil before Chinese market cooperation was more useful. Europe has definitely diminished itself by picking the wrong side on war on Russia, as it is being eaten alive by US and its 5th column inside of Europe. It cannot be too desperate to be friend/slave of its abuser.
