Not really. If the accusations are true they'd hold on to them, and if they are false they'd likely face consequences on dropping them.

Who knows, the accuser, Anna Ardin left Sweden for Israel shortly after making the accusations and has not made a single comment since then as far as I know.

Doesn't twitter count? https://twitter.com/therealardin If you mean that she hasn't made "a single comment" about the allegations, then it is possibly so that she is a public figure and doesn't want to be "the girl who accused Assange of rape" for the rest of her life.

Oh yeah, the whole government smear campaign theory. That a state could only muster "might have had quasi-consensual sex and not worn a condom".

That was the best they could come up with in a setup?
