I'm not saying he is innocent, but if he is, he has every reason to believe this is a politically-motivated frame-up. So, if he is innocent, why go to Sweden? Probably, even as an innocent person, the frame-up would succeed.
As such, his unwillingness to go hardly says anything about his guilt or non-guilt.

If he is in fact guilty then it would be rather odd for him to regard this as a politically-motivated frame-up, so I guess you are saying he's innocent.
I think it is implausible that politics have not played some kind of role in proceedings (e.g. the linked article does not explain the use of an Interpol "red notice"). But if it were a frame-up you'd think the accusations would be more serious and consistent. If he were to go to Sweden and then suddenly be extradited to the US to face serious criminal charges it seems to me that this would make his case.
