Military prosecutors have decided to bring the maximum charges against U.S. Army Private Bradley Manning after he admitted to the largest leak of state secrets in U.S. history. In a bid to secure a reduced sentence, Manning acknowledged on the stand last week he gave classified documents to WikiLeaks in order to show the American public the “true costs of war” and “spark a debate about foreign policy.” Manning pleaded guilty to reduced charges on 10 counts, which carry a maximum sentence of 20 years in prison. But instead of accepting that plea, military prosecutors announced Friday they will seek to imprison Manning for life without parole on charges that include aiding the enemy. Manning’s court-martial is scheduled to begin in June.
