First, not our problem.
Otherwise, understand how the Assad’s have kept an iron grip on authority AGAINST a 60% plus Sunni majority. Assad, like his father, deals directly with 50-60 key people is his government. These people don’t have board meetings. Any coalition among these people is a threat.
Trust that there are no Sunni’s holding any high position in government, holding senior military positions and certainly no military pilots. Can he risk a disgruntled Sunni dropping a bomb on his palace -no!
Where Sadam Huessain was a Sunni suppressing a Shia majority, Assad (Alewite -Shia sect) is suppressing a Sunni majority.
Depose Assad and his (Alewite/Shiite) government and it’s Iraq all over again, but with a Sunni majority.
I agree it's not our problem, in the sense we shouldn't get involved. But we do have to watch it, because it could become our problem. But I actually think the events are somewhat in our favor. Syria's split had actually helped us. We aren't the focus of the Middle East now.
