What motivates you to say such things? Is it the power trip of thinking you'll scare someone more competent that you? Seriously, you should have added at the end "and they'll get your little dog, too!"
Did them rocking the boat a little shake your misplaced foundation in the infallibility of our western military?
Your reaction is infantile, and more importantly, your anger is misplaced.
The proper reaction is shock that some teenage script kiddies could hack into NATO at all. You should be venting your anger at the utter incompetence our military displays.
As for those teenage script kiddies at Anonymous, I do believe, if you ever wanted to, you could probably get a job at NATO securing their servers now. I'd also recommend you don't disseminate the data you found, as you don't know what the consequences of releasing that information may be, or the lives it could cost.
Point made. Leave it at that.
