An outright victory by Syria’s rebels would be a disaster
Many of the fighters currently battling the Syrian regime honed their guerrilla skills in Iraq, learning urban combat techniques fighting Americans in Iraq from 2003 to 2007. Those who were not killed in Iraq made their way back to Syria (the largest entry point for foreign jihadis entering Iraq during that war), and have taken up arms against their own regime. Their ability to kill a large number of regime forces from the outset of this current round of civil war is indicative of the skill set they already possessed 19 months ago. The body count of 4:1 during the early months of this civil war — that is, four opponents killed for every soldier killed — is quite good for unorganized insurgent groups.
In fact, the insurgents might be too good. Neither Syria nor the region would be well served by a decisive victory by either the Assad regime or by the opposition. Breathless supporters of Syria’s revolution need to be careful what they wish for. The most powerful elements of Syria’s armed opposition would almost certainly be no friend of liberal democracy were they to seize power for themselves. Consider this: The dissidents who brought down autocratic governments in Egypt and Tunisia, even the political Islamists among them, were far more politically liberal than what we see in Syria. And look at those countries now.
What, then? It is not fashionable to say so, but a negotiated outcome remains the best solution to end the killing and prevent the worst elements from either side ruling Syria. An outright opposition victory would likely produce a momentary air of euphoria before the steep decline toward autocracy and darkness begin.
