minor, o.k. not minor point... you're confusing rendition w/ extradition. In the Snowden case the U.S. was prepared to have him extradited to the U.S. if they could get their hands on him. Rendition is sending a prisoner to another country that has more lax laws regarding interrogation.
So... please provide links/proof where this was going to happen to Assange, cause all I've seen to date is his paranoid claims that he would be extradited to the U.S. if he was sent to Sweden.
As mentioned before lot of paranoid conspiracy theories, very little proof.
