Two years ago, Julian Assange had a well-deserved reputation as a champion of transparency.
The WikiLeaks founder had overseen the responsible release of hundreds of thousands of classified cables from American embassies. People worldwide were provided with a better grasp of international relations and, more particularly, the wars in Iraq and Afghanistan.
Today, however, Mr Assange's credibility has been shredded. As much has been reinforced by his hugely ironic presence in the Ecuadorean Embassy in London for the past two months. And, even more so, by his recent attempt to re-establish his credentials as a guardian of free speech.
Speaking from a balcony of the embassy, Mr Assange portrayed himself as a fearless victim of United States oppression who had fled there to avoid imprisonment in America for his WikiLeaks work. The US had a stark choice, he said. "Will it return and reaffirm the values, the revolutionary values it was founded on, or will it lurch off the precipice dragging us all into a dangerous and oppressive world, in which journalists fall silent under the fear of prosecution and citizens must whisper in the dark?"
This played well with hard-core supporters gathered below. But Mr Assange's calculated avoidance of the actual reason he had broken the terms of his bail and sought refuge in the embassy can only have further damaged his reputation. He decided to seek asylum in Ecuador not because of any threat to his freedom posed by the United States but because he is wanted for questioning in Sweden over wholly unrelated rape claims by two women. A 10-minute speech that contained no mention of this was hardly the hallmark of a man committed to openness, honesty and accountability.
