U.S. warplanes call off surveillance of an ISIS convoy, at Russia's request

19. I might lack the proper imagination, but I can't think of any ways

that Syria, Russia, or even Trump benefits from having ISIS escape. I suppose some short-sighted "strategy" to move the problem elsewhere could be in play, but that seems like something everyone should know will come back to bite them in the ass eventually.

As for the letting loose on ISIS, I was thinking they may be worried about the optics of Syrian soldiers killing fleeing ISIL members in mass. I may be wrong, but wasn't it mentioned that in those fleeing convoys there were family members of ISIL members? At least that's something I would be concerned about if I were them. Then again, they might be past the point of even caring about international opinion.

I dunno.
