Last I heard, the investigation against Assange was dropped some years back. Then a new, presumably more pliable, Swedish prosecutor reopened the case, against even the original complainants wishes. The UK govt refused to allow the Swedish police to interview Assange while he was in the embassy. There was never an international warrant for his arrest or even specific charges filed. One of the complaints against him was a peculiar item of Swedish law whereby a split condom = rape.
Make of it what you will. Its just the US being their usual arm twisting selves AFAIK.
Big brother because history should not be twisted to suit a political agenda.
