A while back the Obama administration drew a "line in the sand" of sorts on Syrian govt forces possible use of chemical weapons. It just wasn't going to be tolerated you see.
Since this line was drawn, there are reports that there is the possibility that Syrian forces have indeed used these same weapons in limited strikes. Whether true or not is any one's guess. I would imagine that American mainstream media types would shy away from reporting an incident for "political" purposes. At any rate, I am hesitant to believe that this administration is really serious about their implicit threats of military engagement with Assad loyalists over the issue.
The Syrian civil war is a geopolitical danger to be sure. Not your average who cares Mohammedan vs Mohammedan conflict. This one has the potential (however unlikely) to involve major players in an adversarial military relationship. Carl in Jerusalem email@example.com has reported that a Soviet err Russian flotilla, including warships and assault elements, is gathering off the Syrian coast. If the report is correct (and I'm sure that it is), this throws an interesting twist into the line in the sand thing that the Obama administration has bleated of.
What if Syrian forces under Assad did use chemical weapons to gain the upper hand in what is becoming an apparently lost situation? In the unlikely event that the Obama regime is serious about getting involved over such an action, would the presence of Russian forces in the vicinity be a deterrent? Probably and rightly so. At this time the Syrian conflict is not worth getting involved with even without the presence of the Russian military in the region. The Russian forces would be swept aside rather quickly if it came to that, but I would imagine that just their presence alone would deter any real military action against Assad. Just not worth the risk.
That might be a good thing. Assad is evil obviously, but he is a well known evil.
It may be best to just let this thing play out the old fashioned way and be prepared to deal harshly with the aftermath if need be.
