Obama Taking US Into A Proxy War with Russia?

Consider all of the above and then consider this report from Debkafile: "US President Barack Obama has ordered the US Navy and Air Force to accelerate preparations for a limited air offensive against the Assad regime and the imposition of no-fly zones over Syria, debkafile reports. Their mission will be to knock out Assad’s central regime and military command centers so as to shake regime stability and restrict Syrian army and air force activity for subduing rebel action and wreaking violence on civilian populations."

I have but one question: WHY?

So we know that Russia is sending attack helicopters to Assad, which will, no doubt, be used against the Syrian rebels, and now, the US is going to spread a no-fly zone over, at least, a part of Syria within which those choppers will be shot down the moment they leave the ground.

We have known for months that Russia has troops on the ground in Syria assisting Assad's military. And we SUSPECT the US has, uh, "advisers" working with the rebels. One has only to consider recent press reports from Syria in which the reporter(s) wonder how the rebels seem to have suddenly become much more sophisticated in their battle tactics and war fighting organization. And we haven't even mentioned the small arms the US is making available to the rebels through mutual allies. (Of course, the US denies this -- but of course!)

What we have in Syria is quickly shaping up to be an old fashioned "proxy war" between the US and Russia just like in the "good ole days" of the Cold War.
