This chaps father made it sound like his son was avoiding a US airbase out of idealistic reasons, despising as he does, America 'the great satan' for its operation of Guantanamo.

I suggest however, that his avoidance of US  facilities has more to do with his former marriage to Omar Khadrs sister and the possible dislike the USA may have  had of these circumstances.  I think this guy is afraid the US may know something he doesn't want them to know.
