Hmmm
There you go the US we'll get him sooner or later
Federal Criminal Lawyer, Douglas C. McNabb, points out that a U.S. extradition law between Sweden and the U.S., pursuant to the article 6 of the supplement to the extradition treaty between the U.S. and Sweden, can assure Assange's extradition to the U.S.
Sweden can transfer Assange to the U.S. to stand trail for any U.S. federal criminal charges before he faces charges for sexual offences in Sweden. If convicted, Assange could also serve his full sentence in the US, before ever facing the alleged charges in Sweden. This law does not exist in the UK.

Which basically means if the swedes get him to Sweden then he will be handed over to the Yanks even before they interrogate him on these 'charges'
