The US military has designated Julian Assange and WikiLeaks as enemies of the United States - the same legal category as the al-Qaeda terrorist network and the Taliban insurgency. Declassified US Air Force counter-intelligence documents, released under US freedom-of-information laws, reveal that military personnel who contact WikiLeaks or WikiLeaks supporters may be at risk of being charged with communicating with the enemy", a military crime that carries a maximum sentence of death. The documents, some originally classified "Secret/NoForn" - not releasable to non-US nationals - record a probe by the air force's Office of Special Investigations into a cyber systems analyst based in Britain who allegedly expressed support for WikiLeaks and attended pro-Assange demonstrations in London. The suspected offence was "communicating with the enemy, 104-D", an article in the US Uniform Code of Military Justice that prohibits military personnel from "communicating, corresponding or holding intercourse with the enemy". US Vice-President Joe Biden labelled Mr Assange a "high-tech terrorist" in December 2010 and US congressional leaders have called for him to be charged with espionage. Sarah Palin and Mike Huckabee - both once involved in presidential campaigns - have both urged that Mr Assange be "hunted down". Mr Assange's US attorney, Michael Ratner, said the designation of WikiLeaks as an "enemy" had serious implications for the WikiLeaks publisher if he were to be extradited to the US, including possible military detention.
