It's a stupid question, but you have to stand back and look at some simple issues.
- While everyone was pumped up months ago when Syria handed over all of it's chemical weapons to be disposed of.....you really couldn't say that they all had been given over.
- The device for the chemical weapons.....a type of bomb that would be fitted onto an aircraft. Not a crude tank hung off a helicopter, or an artillery-shell. Does ISIS have aircraft? No. Does Syria have aircraft? Yes (oddly the type flying from this base that got bombed out by the US).
- Did the Russians likely figure out the whole bomb thing and the odds of it being from Assad's Air Force? They'd have to be idiots if they didn't figure that out in five or six hours.
- The use of the chemical weapon making the Russians look bad? Well....yeah. They can talk to Assad and try to convince him of the stupidity involved....but it doesn't matter.
Who knows.....maybe Putin called up Trump and laid the cards on the table and just said....you know....you were to bomb this one air base under Assad....we wouldn't be terribly unhappy. And by the way, here's the coordinates for every building on the base.
After the event, Putin can look furious for about 60 seconds, and talk about the evil Americans. Then he goes behind the door and just grins because Trump fixed Putin's problem and will ensure this doesn't happen again.
Maybe I'm wrong, but it just seems so scripted out.
