This is separate from the question of who really did the bombing, as that question is settled. Read: Assad did it, with help from the Russians, the Iranians, and Hezbollah. FYI: informed adults are decidedly not confused on this point.
Necessarily, this is also separate from the hand-wringing over why President Trump warned of his intentions. I would also point out that had Barry warned of his intentions, he would very likely not have carried them out. See: Obama, Barack; Syria, Red Line; Weapons, Chemical; Response, Failure to Follow-Through and Use.
