FORT MEADE, Md. Pfc. Bradley Manning put U.S. military secrets into the hands of Osama bin Laden himself, prosecutors said Monday as the Army intelligence analyst went on trial over the biggest leak of classified material in American history.

Manning's lawyers countered by arguing that he was a "young, naive but good-intentioned" soldier whose struggle to fit in as a gay man in the military made him feel he "needed to do something to make a difference in this world."

Manning, 25, has admitted turning over hundreds of thousands of documents to the anti-secrecy website WikiLeaks, pleading guilty earlier this year to charges that could bring 20 years behind bars. But the military pressed ahead with a court-martial on more serious charges, including aiding the enemy, which carries a potential life sentence.
