Bradley Manning, Whistle-blower or Traitor?

Army private Bradley Manning is now facing court-martial at Ft. Meade, Maryland on charges of aiding the enemy and espionage, among others. In a recent pre-trial hearing, Manning admitted he's the source of the 700,000 military and government documents uploaded to the Wikileaks website three years ago. The documents caused a sensation, and sparked dozens of stories in the press about the wars in Iraq and Afghanistan and US secret diplomatic activity around the world. Manning's admissions could get him twenty years. The government's charges of aiding the enemy and espionage could get him life without parole. Is he a traitor, as his detractors say or a whistle-blower hero, as his supporters call him? Is the mainstream press even covering his case?
