so I will add another thread to this twisted tale. Pro-Obama hold overs in the CIA masterminded this.
We cannot discount the possibility that rogue CIA operatives were complicit in some way. After all, Trump had switched around from a position he had held only a few days earlier, that Assad was not the primary enemy and we should not direct our efforts against him, to suddenly he was number one, and must be removed, at the possible cost of alienating the Russians to the degree they may yet be sucked into the dispute with the US directly.
The Deep State is alive and well and in full command.
