Iran didn't really do anything last year after supposedly having their facilities "totally annihilated". But it used to be that the US was respected enough that public saber rattling and behind the scenes diplomatic efforts would avoid conflict. Sadly, we've done our damnedest to turn that respect into a joke. We used to make deals with people, but the greatest deal maker ripped up all of them and replaced them with nothing on the word better deals were for the taking.
