Makes sense to me. Whoever/whatever did it (if it is real which apparently it is), wants to embroil the US in Syria, and right after Trump emphatically stated the the US was going to pull out.
I just threw that out there. I don’t know anything really, but certainly (I agree) that other players who want to see Assad gone. I suppose follow the money for why. Speak of the Devil - there’s Senator tutu wearing Graham again in front of the cameras pushing Trump on Syria.
