"The bombing was the biggest intervention by Western countries against Assad and his superpower ally Russia, but the three countries said the strikes were limited to Syria's chemical weapons capabilities and not aimed at toppling Assad or intervening in the civil war."

It would appear that apologists for Assad and Putin are opposed to seeing their chemical weapon capabilities degraded especially when it's the big, bad "West" that's doing the job. At least the Syrian people are safer now and that's what counts.
