Say what you will about Qaddafi, at least he was marginalized and even ostracized. With the exception of his own Libyans/Arabs, he became a threat to nobody after he had his ass handed to him in 1986 and GWB re-established normal relations with the puke.
With his soon-to-be ouster, it's difficult to say who takes power -- but one thing is for sure, radical Islam is damned likely to throw their hat in the ring.
Radical Islam is what concerns me - not Qaddafi.
