In that case he should go to Sweden. Staying in the UK or going back to his native Australia would ensure he's whipped off to the US, if the US decides to go for him. In South America, if the US wanted to, he'd be dead within minutes.
But, in spite of the list or right wing hot air nutjobs you posted, all Assange has done is publish information stolen by others. Something Greg Palast has been doing for decades without ever being locked up by the US. A man who incidentaly has this to say about Assange:
"Do you remember the reporter who put his by-line on the Pentagon Papers story? Of course not, he didn't risk a thing. Julian Assange didn't risk a thing either - except excess TV exposure and an excess of blonde groupies. The hero of the Wikileaks/Guardian/Times/Spiegel exposure is Pvt. Bradley Manning.
"NO ONE gives a sh*t about this heroic man who is rotting in Obama's prison cell. Not Assange (who did nothing to protect him, and does nothing now), nor the Left happy to use his information nor the New York Times which is happy to take the bows for material Manning risked his freedom for.
"Assange is like all publishers except that he erases the names of the 'author' from the books. He will join his fellows in that ring of Hell devoted to those who wear the mantle of courage stolen from others.
"I salute Pvt. Manning. It is Manning, not Assange, who will save this world."
