If  one asks current or former WikiLeaks associates what their greatest fear is, almost none cites prosecution by their own country. Most trust their own nation's justice system to recognize that they have committed no crime. The primary fear is being turned over to the US. That is the crucial context for understanding Julian Assange's 16-month fight to avoid extradition to Sweden, a fight that led him to seek asylum, Tuesday, in the London Embassy of Ecuador.

The evidence that the US seeks to prosecute and extradite Assange is substantial. There is no question that the Obama justice department has convened an active grand jury to investigate whether WikiLeaks violated the draconian Espionage Act of 1917. Key senators from President Obama's party, including Senate intelligence committee chairwoman Dianne Feinstein, have publicly called for his prosecution under that statute. A leaked email from the security firm Stratfor – hardly a dispositive source, but still probative – indicated that a sealed indictment has already been obtained against him. Prominent American figures in both parties have demanded Assange's lifelong imprisonment, called him a terrorist, and even advocated his assassination.
