One of the many peculiarities in this strange case is that the evidence for any such thing is non-existent. The Pentagon has admitted that it failed to find a single person covertly working for the US who had been killed as a result of the WikiLeaks disclosures. This failure was not for lack of trying: The Pentagon had set up a special military task force, deploying 120 counter-intelligence officers, to find at least one death that could be blamed on Assange and his colleagues but had found nothing.
Other allegations against Assange put forward by the lawyers for the US government are similarly flimsy or demonstrably false, yet he is still in real danger of being sent to a maximum security prison in the US after the court makes its ruling on 4 January. Once there he faces a sentence of up to 175 years and, whatever the length of his incarceration, he is likely to spend it in solitary confinement in a tiny cell.
The Assange case creates a precedent that mortally threatens freedom of the press in Britain. If Assange is extradited then any journalist who publishes information that the American authorities deem to be classified, however well-known or harmless it may be, will risk being extradited to face trial in America. The US secretary of state, Mike Pompeo says that non-Americans like Assange do not enjoy First Amendment Rights to free expression.
