The Other Syrian Blood-bath

The one that hasn't happened yet:

Christians were as common in Syria as in Egypt, before their numbers were immensely swelled by refugees from Iraq — well over a million fleeing up the Euphrates River valley, from anti-Christian persecution by Iraq’s Islamists. By now, there could be more than four million Christians within Syria’s borders.

When the Assad regime falls, it will be open season on them, on the Alawites, and all the other minorities. Granted, Assad is a monster who has earned an ugly fate. But at what expense should we indulge the fleeting satisfaction of deposing him?
