'In January, Assange said he stood by an offer to go to the United States providing his rights were upheld and if former military intelligence analyst Chelsea Manning, ...... was freed.'
I don't think he would go to US now that Manning is freed.  He is not a man of his words.  He skipped bail after supporters and friends raised money and put up collateral to meet the bail condition and left them out cold.  He can always say he is not going because his right 'is not upheld'.  An excuse.
He also said he will not forgive or forget the investigators.  We all know what does it mean.  He will use his favorite weapon, leak private information among others to exert revenge on these people and Sweden.  Just a matter of time, stay tuned.
