Navy Commander Christopher Homer ( I think is his last name) who is with the Institute of the Study of War....said that even a missle strike, because they cannot get air clearance, will take 45 minutes to reach it's target, so they cannot hit anything that's a hard target because anything that can be moved will have time to do so....especially since Russia will let them know as soon as the missle fires.
About the most that can be done are soft targets...like the airports...which would of course affect their planes from leaving and arriving..and this their air supply routes from Iran....which would then have to find other means of supply.
Furthermore the Syrians supporting Assad are already camping out at the sites considered targets, as human shields..by their own choosing.....as seen here in one location...
.....set up a camp at the foot of Qasioun Mountain just outside the capital on 'Tuesday'
