Had Assange been extradited to Sweden to face the charges against him there is no way on earth that the USA would have dared face the approbrium that would have followed any action such as you describe. I will give you a name that illustrates this perfectly - Alexander Litvinenko who your pal Vladimir Putin had murdered. Litvinenko's murder was linked to another assassination Putin ordered in Russia, that of Anna Politkovskaya. No court cases will ever remove the stench of these acts from Putin's hands.
