Riyadh wants the US to bomb Syria, so much so that MBS has offered to take part himself if that helps:
On Tuesday, Crown Prince Mohammed bin Salman announced that Saudi Arabia could take part in military action in Syria. The Crown Prince is wrapping up a three-day visit to Paris.
“If our alliance with our partners requires it, we will be present,” Prince Mohammed said at a news conference with Macron.
Of course as everybody understands, the butcher of Yemen is a PR liability and allowing him to take part would take away much of the shine of the supposedly morally upright attack on Syria. For this reason it is doubtful MBS offer will be tested, albeit with Trump you never know.
