Three years after his arrest in Iraq for allegedly causing America's worst ever national security breach, US Army private Bradley Manning finally goes on trial Monday over his disclosures to WikiLeaks. Manning, who faces a possible 154-year jail sentence, has offered to plead guilty to several offences but he denies prosecutors' most serious charge - that he knowingly aided the enemy, chiefly Al qaeda and Osama Bin Laden.
The trial follows an exhaustive series of preliminary hearings that outlined the government's case against Manning, 25, over leaks of diplomatic cables and war logs that caused huge embarrassment to the United States and its allies.
The soldier's supporters argue that his actions shone a light in the darkest corners of the US-led wars in Iraq and Afghanistan, as well as exposing the reasoning behind American foreign policy decisions.
His opponents, however, contend that he is a traitor whose behaviour wantonly endangered the lives of people around the world, including US citizens. The lengthy nature of the case against Manning - he was arrested in May 2010 while serving as a military intelligence analyst near Baghdad - has revolved around the complexity of the charges he faces and his treatment in custody.
His legal defence team successfully argued that he had been subject to unduly harsh detention methods from US military personnel and, consequently, he will receive a 112-day reduction of any eventual jail sentence.
While the case has served as a cause celebrate for civil liberties advocates in the United States, the government contends that Manning's actions helped the nation's enemies in a political era defined by the threat posed by al qaeda.
It is that charge that Manning disputes, though the soldier admitted in testimony earlier this year, an unauthorised audio recording of which was later published online, that he did in fact pass a huge cache of files to WikiLeaks.
He said he did so to start a public debate, but the military judge hearing the case, Colonel Denise Lind, has warned she will not allow Manning's trial to turn into a wide-ranging forum on the rights or wrongs of US foreign policy.
Manning has offered to plead guilty to 10 offences, including breaches of military discipline and good conduct, which could see him sentenced to 20 years under the courts-martial process at Fort Meade military base in Maryland.
However, he could face a maximum term of 154 years in jail if found guilty of the more serious charges, including that of "aiding the enemy."
