Syria kind of brought the hellfire on themselves using the chemical weapons, that was seriously a stupid move.
I don't fully believe that Syria has used chemical weapons, sounds like another alibi to invade another country of far east, for materialistic reasons (oil, tactical purposes) as well as to close down towards far east and Russia to keep an eye on them.
They may be in possession of those weapons, but I don't think they, as the country officials have used it, if anything, some 'terrorist' or revolution groups have done so to cause this major harm. Who would bomb their own people to start up this whole thing with USA? Obviously either double agents working for USA or other groups allied to US and EU... If they are in possession though, we are in big trouble if anything happens, simply because world is corrupted and moving those weapons to EU or US would not be a massively hard thing to do... over time of course... which could start WW3... We aren't too far from another global war, it's been the longest term in official human existence within which we have lived in peace (I mean not total war, but other wars were always held all over the globe, many of which are unofficial)...
Odd alliances are being created between scientists, for example Germans seem to work with Japanese (Recently managed to teleport memory held within some sort of computerized circuit, some tiny one)
Also Russians seem to co-work with far-east, such as Syria...
I think it's quite plausible that WW3 comes within next 10 years if we keep walking this path...
