[In its] decision to grant diplomatic asylum to [WikiLeaks'] founder, Julian Assange, ... Ecuador has acted in accordance with important principles of international human rights. Indeed, nothing could demonstrate the appropriateness of Ecuador's action more than the British government's threat to violate a sacrosanct principle of diplomatic relations and invade the embassy to arrest Mr. Assange. Predictably, the response from those who would prefer that Americans remain in the dark has been ferocious. Top elected leaders from both parties have called Mr. Assange a high-tech terrorist." And Senator Dianne Feinstein, the California Democrat who leads the Senate Select Committee on Intelligence, has demanded that he be prosecuted under the Espionage Act. Most Americans, Britons and Swedes are unaware that Sweden has not formally charged Mr. Assange with any crime. Rather, it has issued a warrant for his arrest to question him about allegations of sexual assault in 2010. If Mr. Assange is extradited to the United States, the consequences will reverberate for years around the world. Mr. Assange is not an American citizen, and none of his actions have taken place on American soil. If the United States can prosecute a journalist in these circumstances, the governments of Russia or China could, by the same logic, demand that foreign reporters anywhere on earth be extradited for violating their laws.
