It was a little weird, seeing the news that Syria's rebels finally managed to oust their dictator. On the plus side, one of Russia's clients has likely slipped from their grasp, and it's likely not something they're going to be able to tackle any time soon (another good, concrete reason why you don't go around invading countries like Ukraine - you might lose some of what you already have!). I can only hope more such instances will follow.
On the meh side, it's not like I know a lot about the rebels involved. Fair odds though, they won't immediately revert to gassing their populace and establishing secret prisons or anything like that, so it's likely a plus overall.
Of course, now is where we wait for this to turn out to be a "monkey's paw" wish. Maybe it turns out the rebels are actually Super ISIS? Maybe Russia decides they need to demonstrate their willingness to use nukes on territory they don't intend to occupy? Maybe, flush with success, the rebels decide to push south towards Israel for some reason? Like the old saying goes, hope for the best, expect the worst.
