This is probably just embarrassing.
I should imagine that none of the involved parties want this to go on anymore, I would wager that Ecuador have taken so long because they realise that Assange has dumped them into a political and diplomatic quagmire that really doesn’t have a happy ending for them. Maybe they are hoping that CO19 will storm the embassy after which they can throw their hands up, pretend to be disgusted and then wipe there brow and be glad it’s all been dealt with for them. Either that or maybe they are kicking their heals over it and hoping he eventually dies of old age. Realistically there is no answer that doesn’t have a counter by any party. If the Yanks really want him (which I highly doubt) then I guess a CIA snatch team would have no trouble what-so-ever operating in Ecuador. If the Swedish really want him (which, beyond legal proceedings, I doubt too) then the KSI (literally translated as “The Office for Special Collection", I kid you not) could do the doing just as easily. It just seems that it is a big old mess for everyone and that every government involved are just trying, and failing, to not look stupid.
Long and short of it – even if the charges are a bit hoaky and it’s all a bit weird, if you get accused of sexually assaulting a woman, which is truly a most heinous of crimes, then you lawyer up and go to court. If you are guilty of this then Gitmo, the CIA, SIS or miscellaneous black ops death squads should be the least of your worries because you deserve everything you get.
