Yes, that is my belief. I don't know what he believes.
Well, you seem to be implying that he is being dishonest about his fear of being extradited. As if he is doing this so he doesn't have to answer to the charges in Sweden. Based on your statement, you clearly do believe that he isn't actually worried about ending up in US custody.
I do think he's being dishonest, yes. He has access to skilled lawyers, and his concern about extradition to the US is irrational: it's easier to extradite him where he is.
