President Trump would have completely destroyed his own credibility if he authorized the U.S. military to take action against Iran in response to an attack on a country run by a radical Islamic royal family.

We will come to the aid of Saudi Arabia — and charge them a stiff price for it.
Trump wants Iran to stop attacking Israel, stop building nukes, and mostly stop building missiles. That requires a credible threat of war but not a strike or two like the author envisions. Rather it is a pressure dampaign backed up with strong defense keeping Iran in a non-nuke box.
As for the Saudi radical Islamic royal family, the best we can do is keep them in their box but allow them to defend that box and help if necessary. Remember the lesson of the Cash Hoagie story: the anti-Saudis of which there are a variety, want to destabilize Saudi. That would have huge and awful consequences for the ME.
