Whistle blower or traitor?

The HoS reports:

It’s tough being a whistleblower as Private Bradley Manning has found.

The US Army intelligence analyst is alleged to have provided a huge trove of classified information – everything from Iraq and Afghanistan war logs to 250,000 diplomatic cables – to WikiLeaks in 2010, triggering enormous media coverage and a witch hunt by US authorities to find the leak.

I don’t regard that as whistleblowing. A whistleblower would reveal specific information about specific alleged misdeeds. That is vastly different to stealing and passing on 250,000 cables.
