What the U.S. government really wants is for Assange to die in a British prison. That way there will be no messy trial in the U.S. where the depredations Assange and Wikileaks exposed might be entered into evidence. From Jacob G. Hornberger at fff.org:
Last month, a British court gave Julian Assange permission to continue opposing the U.S. government’s attempts to extradite him to the United States to stand trial for violating the World War I Espionage Act. In truth, what U.S. officials are really targeting him for is that Assange, as head of WikiLeaks, had the audacity to reveal war crimes and other dark-side activities of the U.S. national-security state.
U.S. officials know that Assange’s recent judicial victory is a pyrrhic one. That’s because Assange continues to be jailed under brutal conditions in a maximum-security jail in England — and will continue to be — until his appeal is finally decided. What difference does it make to U.S. officials if Assange is jailed under brutal conditions in England or under brutal conditions here in the United States? The fact is that either way he is being jailed under brutal conditions.
In fact, there is an increasing possibility that Assange will die in an English jail before the extradition proceedings are finally resolved. That would undoubtedly fill U.S. officials with glee, given that they will have been relieved of the task of putting a person on trial for revealing war crimes and other dark-side activities of the U.S. national-security state.
