Couldn't agree more. The Syrian rebels are a loosely associated group with several elements who are radical Islamist and Al Qaeda. This could have easily been titled "DIY Terrorism".
If the residents of New York City rebelled, and managed to take control of 2/3rds of the city, that would be a civil war (or at least I would classify it as such), even if Al Qaeda showed up to participate.
Civil war distinguishes context of conflict independent of methods, terrorism distinguishes methods of conflict indepedent of context; they aren't mutually exclusive categories.
One man's terrorist is another man's freedom fighter. History is written by the victors.
Language designed to engender support for one opinion or another; propaganda. That's all this crap is.
So the Kurds in Northern Iraq that got gassed by Saddam were terrorists? The VC won in Vietnam. Were we the terrorists there? Chiang Kai-shek?
