The fact is, there is nothing like a classical-liberal faction in Syria worth mentioning.
That the Baathists are "secular" is totally irrelevant; so was the Nazi Party and so were the Communists, yet that didn't stop them from killing millions or being evil.
Let's say instead, more accurately, that the Baathist's religion is Power and Keeping the Shiites In Their Place, with the inevitable consequences as the Shiite population exploded over the last 30 years but remained at the bottom of the totem-pole economically, socially, politically, etc.
Like Iraq, Afghanistan and Libya, all the people who could provide democratic government are totally compromised or are exiles or are dead. Like all three places, Sunnis and Shiites are at each other's throats over issues that are so old and dangerous that nobody in their right mind would get in the middle unless they were completely ready and able to sit on them.
If the West wants to do more than talk, we're talking about another long occupation, otherwise it's a complete waste of time, money and human lives.
Sadly, I don't think the West has the spine or the capital to back up it's lofty rhetoric and has done the worst of all possible things; call for change and then sit around looking impotent.
Obama had to be practically dragged to the issue by the Far Left over here and only got involved at all because he had an election to win. I think that his speech telling Assad to step down was the most reluctant speech he's ever given; it was obviously insincere at the time and, well... look how much the U.S. has done since. It's pretty sad when the EU is more excited about doing something about such an obvious mess than we are.
More to the point, the Russians and Chinese have very few reasons to play ball in the UN this time; unlike Afghanistan, it's not an obvious quagmire for whoever was foolish enough to invade it and unlike Iraq, it's not terribly important strategically, so they have very little reason to do anything but commiserate in public... but privately tell us that they will regrettably have to veto any motions to do more than make speeches. The Russians in particular have played this round very well.
And of course, all the Arab League fat cats are in a tizzy; normally, they'd throw in with Assad and help him quell the uprising (he's one of them, after all and they've played that game for decades) but ever since Egypt, I think they're afraid of taking sides in public, lest the same thing happen to them.
The Iranians must be laughing a lot; it's a pretty good revenge over that WikiLeak'd diplomatic correspondence where they practically begged the U.S. to knock out their nuclear program...
Hence stalemate and impotence for two years after Obama told Assad that he should go and the EU tepidly agreed with him, and a hundred thousand dead civilians. And the West will get all the blame, no matter who wins.
