Derrick Shareef must serve 30 of those yearswith five off for good behaviorunless he can get an appeals court to reduce the sentence.
He was arrested in 2006 on charges of scheming to use weapons of mass destruction at the Cherryvale Mall in the northern Illinois city of Rockford.
Federal Judge David Coar said Tuesday he didn't believe Shareef was evil. But he said people could have been severely hurt if federal agents hadn't broken up the plot.
Shareef described himself as a devout Muslim who once admired Osama bin Laden but has now realized violence is wrong.
