I certainly hope this is the endgame for the Syrian war and the US /NATO sponsored attempt to take down Assad, Syria has suffered enough. IMO you are pretty much right about how Trump will handle this, he knows if a shooting war with Russia kicks off China will pile in too and that would be very nasty. Also Trump knows war may be good for some businesses, Rayethon, Boeing, McDonnell Douglas etc., but not for his business. That said, it would be futile for him to go head to head with the deep state so to keep them happy he can bomb a stretch of desert and let mainstream media spin it as a great victory.
Thanks for an enlightening comment.
