While it's interesting to have confirmation that we are also engaging in cyberwarfare internationally, I think this most recent disclosure is evidence that he is in way over his head. This seems to be a desperate attempt to use this information to win safe haven over there. The problem is that the fact that we hack them and they hack us is not news, and no one is going to risk trade relations with the US in order to provide safe haven to him because he told them something they already knew. Also, he no longer has access to top secret information. Therefore he has zero value to them as an intelligence asset, and his mere presence is an enormous liability.
While I am grateful for what he has done, and he's welcome to hide at my place anytime, the moment a warrant is issued, he is toast. He has overplayed his hand, and unfortunately he is about to feel the wrath of a very vindictive US Government. He will be locked up, likely for the rest of his life.
