I don't 'claim' it BT, it's simply a fact that civilised socities have "Heads of State'. Nothing contentious there, I'm not sure what you're problem is.
As for Trump and the USA, Saudi is far too important an ally for any dramatic sanctions to be enforced, a few individuals will carry the can and things will carry on much as before. It might cause yet more foaming at the mouth amongst lefties, but out in the real world, pragmatism always trumps student union politics. Thank god.
