Timeline: http://www.bbc.com/news/world-europe-11949341 Note that between March and August of this year, Swedish prosecutors couldn't be bothered to come to London to question him, allowing most of the charges against him to expire. This in spite of them finally compromising on that, precisely beause the cases would soon expire.
I won't pretend it's a clear-cut case in either direction, but the supicion that he's being unjustly targeted certainly has merit. The victims go to the police, days later, to try to foce him to take an STD test(?) -- the police can't do that, but here have a rape case as a consolation (which of course instantly leaks to the press. And the discussion between the two women about selling their story to the press was just a joke, naturally.) Then the Swedish prosecutors close and re-open the case, the UK spends millions guarding the man, Sweden won't come and question him in the UK (which could be a valid position on sovereignty, but they had finally said they would come to the UK!), and the UK stops guarding him. Yeah, there's definitely nothing fishy here! All the resources spent here have nothing to do with the man in question being an enemy to the United States and their allies. /s
Some of this may be a case of international bureaucratic bumbling being indistuingishable from malicious conspiracy.
I'm open to hearing the other side if I'm missing things. Assange doesn't sound like a very pleasant person, he was probably at the least stupid to get himself ensnared in this, is now by definition an outlaw, and this narrative would be a convenient way to re-cast himself as the victim if he's not. But that's orthogonal to whether he is a rapist.
