There have been many parties involved in both Syria and Libya. Just take the NATO involvement in Libya for example:

Syria is just as complicated if not more so. It turned into a proxy war between the US and Russia and don't forget ISIS and the many different factions who have received funding from multiple sources.

How many people have been killed in the US this year causing and because of the protests at the hands of government and extremists? I don't think we'll be getting a NATO bombing anytime soon. I also can't picture that happening in Nigeria.

If it took the CIA by surprise, why were Syria and Libya on the short list of countries that General Wesley Clark identified as regime change targets in 2007, three years before the Arab Spring?

Because that's a wish list vs. a "we assume this will happen/are actively working on it list"? I'm pretty sure the CIA also shortlisted every Eastern Bloc state in the 80s for regime change. Doesn't mean the SU fell because of the CIA.
