With Sweden's looney toons laws, I strongly disagree.
Assange and his legal team have tried every possible angle. Sweden has very different laws to say the US. This is not unexpected. The English courts have determined that Sweden's justice system is fair and balanced. Assange attempted to avoid extradition by arguing Sweden didn't have the right to issue an arrest warrant, not that he was going to get an unfair trial.
This is an act of total desperation. It does nothing to further his innocence. If the US wanted him they would have extradited him from the UK already - Britain has a long history of being more than happy to comply with US extradition requests. It's why Roman Polanski refuses to visit the UK from France.
This is all about accusations of sexual assault and rape which Assange is totally unwilling to face.
Saying this is all about avoid accusations of sexual assault seems to contradict the actual facts.
Assange cannot have his cake and eat it. It is somewhat hypocritical for Assange to seek asylum on the grounds of human rights whilst denying the women who are accusing him of obtaining due process through the law (most countries agree that due process is in itself a fundamental right).
Then again, Julian Assange could very well be safe in a Swedish prison, relatively impervious to a drone strike.
Rational, maybe. Ethical? Not so much. I don't like the idea of a world where people are free to rape and sexually assault with impunity provided that they are not at home.
