If we should be supporting anyone in this mess it should be Assad, as we have a common enemy. I do not propose taking a side, though. There's no good outcome no matter how we get involved.
I'm convinced the chemical weapons allegations- both earlier on and now- are a ruse by the rebels to get the west involved. A false flag operation, if you will. It would be foolish for Assad to use chemical weapons with the west biting at the bit to attack him. He'd have everything to lose and nothing to gain. Not so of the rebels, who would have everything to gain and nothing to lose by staging an incident.
We need to stay out, but it looks like the die is cast and those within the War Party will get their way.
Washington's Blog takes a good look at chemical weapons allegations.
Reason magazine has 8 reasons not to get involved in Syria.
Pat Buchanan also thinks we should stay out.
There's many more good commentaries on why we shouldn't be involved. I've yet to see one good commentary to convince me we should get involved. The scary thing is the way most of the mainstream media is acting like a press release outlet for the War Party, with hardly any of them questioning the dubious statements and allegations being made over Syria.
