I think you are probably right that Trump and Putin have choreographed a harmless show of force by the US so Trump can look brave and strong. He will probably bomb another empty airfield, just like last time, that the Syrians can repair in a day or two. If, however, Putin follows through and blocks the US missiles, it will be a huge humiliation for the USA, forcing us into greater conflict. Let's pray that your prediction is correct. The incident will be over in a few days and it won't do Trump any good in stopping Mueller from draining the swamp named Trump.
