Trump looks as though he is facing potentially the most difficult foreign policy decision of his Presidency to date and it looks like he has absolutely no idea what to do.
It seems entirely plausible that Iran is behind the strike against the Saudi oil facilities. It just seems too sophisticated and well executed to have really been carried out by Houthi rebels hiding in some sort of bunker. What the thinking behind Iran daring to do this is not easy to figure. They may have felt that given Trump's trashing of Obama's nuclear containment deal, they had little to lose in pushing the Saudis and US in to some sort of action. It puts the US I a despirate position. Either they role over and reveal themselves to be a paper tiger or they do something significant against Iran with the possibility of all hell being let lose. My guess would be that if you had a war between Saudi and Iran and others get involved Trump will figure oil prices will go through the roof and the world maybe pushed into recession and Trump's chances of being reelected and avoiding jail may be significantly reduced. My guess would be some sort of face saving cruiee missile strike which primarily rearranges the sand dunes but does not cause sufficient danage to necessitate retaliation. Probably the Saudis will go along with it as I am sure they have been flabbergasted by the way that a single strike seems to have taken out half of their oil production. I think their immediate concern will be a massive build up in anti missile defenses which will take time.
