putting national security at risk is a different story
"national security" is a vague concept; and either way security by obscurity doesn't work for terrorist groups with the right resources.
If "national security" is compromised from the leaks of a couple of documents to the public, than the nation wasn't so secure in the first place. After all, if Wikileaks got a hold of those documents, how hard do you think it is for somebody with a couple of millions in cash and the right connections to do it?
But yeah, we should think of the children.
