His paranoia is understandable. And justified.
He was involved in the release of highly sensitive information which reflected poorly on a superpower. A superpower which, in recent years, had shown itsself willing to resort to secret kidnappings and off-the-records prisons, and to detain people indefinitely without charge of trial. If I were in his place, I'd suspect the US was plotting to get hold of me too. He may well even be right.
Just because you are paranoid doesn't mean they aren't out to get you.
(Doesn't make him less of a general arse, though.)
