Not sure I agree with your analysis. When your enemy is in the midst of a civil war, that's a good thing. Now, if the Iranian freedom fighters would start making life difficult for the mad mullahs, we might be able to put a little more pressure on Kim Jong Il.
If Syria has a civil war it would not be a favored result. Ideally Assad would remain and would see the light. No muss, no fuss, Khadaffi style.
