I’m just not sure now which way they’ll swing....as you said , it’s a balancing act.....but no doubt in my mind that none are what one could really call Pro-US apart from how they benefit by ‘appearing so’ which they have to show with the religious Imams hard on their heels.
Going to be interesting either way...but in the end they will oppose us.
I don’t look for Saudi Arabia to make any changes in their direction over the long haul.
