I really don't know that much about it, but hey, this is a new era - The Golden Age of The Dunderhead - so knowing nothing qualifies me to make all the decisions, right?
It looks to me like Trump intends to throw in with Putin and Assad, and just bomb the whole thing flat. Of course, that's the kind of thing Trump loved to say during the Scampaign® with all that crap about what a lousy leader Obama is on this one - something Grampy McDumfuck and Huckleberry Butchmeup are flogging again - which leads me to believe he has absolutely no intention of following thru on it (Mr Unpredictable, remember?).
Here's the thing: You take a Rent-Seeker like Trump and put him in charge of the US military, and you get the ultimate REMF. Add Trump's thin skin, short temper, a propensity for revenge while hiding behind bogus "Information Sources", and you get a guy who makes lotsa bad decisions, which makes for lotsa dead people.
It's nothing but a transaction to Trump - Cost/Benefit - he gets paid while you do the work. He collects the tribute while we pay for the funerals.
Because it bears repeating: This isn't politics. This is a fucking robbery.
