Wrong. Sweden *additionally* has restrictions in their extradition law banning extradition for intelligence and military crimes, beyond the general EU restrictions. Which is why they refused to hand over Edward Lee Howard (the most major CIA defector to the USSR) after only a very brief preliminary investigation; it's simply banned to extradite for such crimes. Think the US didn't really want Howard? Not to mention that the UK *also* has veto over any extradition, as the sending state under a EU surrender request , so he'd be *safer* in Sweden (it's an extra barrier). And here we're talking about the UK, the country that wouldn't even hand over Gary McKinnon, the most damaging hacker of US military systems on record, because "he has aspergers" (as if Julian I-Have-To-Wear-Specific-Jackets-To-Write-Specific-Documents Assange doesn't?). Think the US didn't really want McKinnon? And of course, the ECHR has veto power over every step of the way - the ECHR which is often considered the greatest refuge for people fleeing extradition on Earth, the same court body that goes so far in terms of protecting the rights of suspects and prisoners that it ruled that you can't ban UK prisoners who are in prison from voting or sex offenders serving time for their offenses from having access to (government paid) reproductive services.
And what praytell was the plan here? Instead of waiting until Julian, famous for being a globetrotter, goes to a trivially easy nation, let's insist on getting him in the nation that *he himself* chose as the most difficult? And then let's not have a single person even watch him to warn the Swedes when he leaves or warn the British when he jumps bail? And let's complicate the whole thing with competing local charges?
The conspiracy theory is so far into fantasyland that parents in Narnia could use it as a bedtime story for their kids. And Assange knows this. Whenever it's pointed out, he always changes the subject. He lost one of his biggest supporters this way, Jemima Khan, who posted a huge chunk of his bail, but now considers him a "new L. Ron Hubbard" because of his dodges on this issue.
