That is plausible, e.g. we would not extradite a person for one offence if it was likely the offender would then be charged with a capital offence. However, you need quite a lot more than the accused's assertion that this might happen. Under what Swedish statute might Assange be unjustly extradited to the US (and indeed, for breaking which US law? They haven't actually charged him with anything because I don't think he's done anything illegal there).
