I have no opinion on what is happening to Assange. I don't know enough facts. I find it unlikely that there is a big conspiracy involving America though. I find it somewhat ridiculous the number of appeals you can have. Assange lost on the original verdict, then the appeal. He can then appeal again. I assume if that fails he can appeal to some EU court? Its like the deportation of Abu Qatada. One has so many appeals…
You find it unlikely because you are clearly ignorant of the facts.
You really need to widen your reading with an opinion like that. I suggest books like "Classified Woman" by Sibel Edmonds, "Ghost Wars" by Steve Coll or "Family of Secrets" by Russ Baker.
Note I'm not saying there IS an American conspiracy. I'm saying the fact that you find it UNLIKELY that there is a conspiracy is naive and ignorant of how American power actually works (as opposed to how it advertises it works).
