I seriously doubt that intervention is the heart's desire of the President.
Regardless of whether he eventually deems it necessary. Bernie Sanders is more of a polished gentleman (not to mention older) than Grayson, whose spitfire personality can lead him over the edge a bit now and then. Goes with the territory I suppose. But it also makes him less viable or worthy of a future presidential candidacy, and in this case I still question his motives for those statements.
When I'm not privy to the deepest intelligence the WH possesses, and remembering the Holocaust all too well, I'm always going to lean towards trusting the judgment of an ethical, deliberate, practical, long range strategist over just about anyone else no matter how persuasive they might be. Sometimes it's a curse seeing both sides of an argument, but eventually I have to make a choice - and like most people, my choices tend to follow a certain trajectory.
