From a constitutional perspective, it’s amazing that POTUS decides on his own judgment, or whim, whether and how to go in to Syria and whether and how to leave, and everything else about the sprawling global war against IS and AQ, and associates, and associates of associates, etc
Our 17-year war is entirely under control of POTUS. Congress authorized a relatively narrow use of force on 9/14/01 & has appropriated & hand-waived ever since while presidents—Bush, Obama, Trump—have determined practically everything else.
Eg: Heavy footprint in Afghan. and Iraq, plus surge; light footprint in Iraq and Afghanistan plus expanded drones; expanding war geographically to many nations; expand to associates and their associates; expanding to ISIS; expand to Syria; leave Syria; when/how to use cyber; etc.
