This is, obviously, a very welcomed development, no matter where you might stand politically or how you view americas role in the middle east. Last night, we were staring into the abyss. Tonight, we arent. That said, if, in fact, President Trump took the offramp here, the question remains, was it from a highway that he, himself, built, with his decision to kill general soleimani.
