You don't know that.
And BTW, if that were the case, and if we had internal intelligence reports that showed that, then why not exterminate both sides.
That's called the War on Terror. What happened to it?
You don't know that.
No one DOES know. However, a disproportionately high number of jihadis into Iraq after the fall of Saddam came from eastern Libya, the base of the current rebellion. Plus, al-Qaeda openly supports them vs. Gaddafi.
Exterminate both sides? That'll win us friends.
We're not as powerful as we once were, so it's time to look at others taking up the slack from time to time. Plus, in case you haven't noticed, we have a nearly nonexistent southern border through which jihadis are entering the U.S. Let's apply the War on Terror there first.
