(<a href=www.latimes.com target=_blank>L.A. Times) As it struggles to combat Islamic terrorist networks, the Bush administration has quietly built an intelligence alliance with Libyan leader Moammar Kadafi, a onetime bitter enemy the U.S. had tried for years to isolate, topple or kill. Kadafi has helped the U.S. pursue Al Qaeda's network in North Africa by turning radicals over to neighboring pro-Western governments. He also has provided information to the CIA on Libyan nationals with alleged ties to international terrorists. In turn, the U.S. has handed over to Tripoli some anti-Kadafi Libyans captured in its campaign against terrorism. And Kadafi's agents have been allowed into the Guantanamo Bay detention camp in Cuba to interrogate Libyans being held there.
