There is already a hot cyber war going on with China, it isn't even really 'classified', I am sure the full extent is classified, but its well known that china's cyber force have been relentlessly attacking US government and commercial assets on a large scale for years. That the US is doing the same thing, while not publicly stated, i would think is a pretty reasonable assumption.

He is literally committing espionage, I am glad the privacy related items came out, and frankly I hope the bulk of what he stockpiled eventually becomes public knowledge.

But he is without doubt releasing US government secrets to a 'friendemy' foreign nation with the express intent of personal benefit. thats spying, text book, thats not whistle blowing.
