McKinnon the Man
Someone should really interview him, and if done well that tends to stop US involvement, they are media centric.
It is daft, one UFO hunter, sort of X Files really, and that is the spin to put on it, the US military should be able to secure their systems, and they didn't back then. So, whilst his actions have caused damage in as much as the computers need to be reinstalled, they would have to be reinstalled anyhow because of how bad their security was.
It is not the case he used advanced technique, he just used simple password cracks and passwordless accounts, he may have escalated and used the systems to compromise further, but again their networks should have caught this stuff, and it is not that hard to do.
It wasn't an attack to destroy, it was to find information on UFOs.
There is also the matter of torture that the US appear to have allowed, and on that alone all extradition treaties should be null and void under international law.
