Even extremism is a function of outside interference because the jihadists give them a chance to expel foreign interlopers, so they side with the CIC & Al Shahab.

Well, that's what happens when you stick your dick in the pudding with constant attempts to establish a government in a place that doesn't want one. If the UN and US weren't feeding cash and support to the so-called "government", it wouldn't last long, many of the warlords would cease, eh, warlording, and the Islamic extremists would cease to have reason to exist and would ultimately disband.
