It's far from trivial, the worth of the TLAM hinges on the veracity of your claim.
Any evidence on your part to support your claim would be helpful.
Also, are you sure the Syrians had anything working at that airfield even to shoot at TALMs?
Are you sure they didn't? At one time Syria had a robust IAD network. As there were numbers of Russan personnel there, wouldn't standard force protections dictate their presence? Your lot made quite a bit of noise about deploying the latest and greatest IADS after the Turks shot down your aircraft, one would think you would be ready for what is (and was) the most predictable method the US would engage. Most important, there are not 59 smoking holes (other than the targets) where Russian/Syrian IADS engaged the TLAMS. As you put it "easy targets" should have your ministry (and the Syrian equivelant ) talking up the effectiveness of their weapons, that's not in evidence.
