I dunno about that cosmic. If he could be extradited by the US from Sweden he certainly could have been from the UK while he was hanging out there before the Swedes tried to extradite him and he ran into the Ecuadorean Embassy. There seems to be two issues on the rape accusation: what constitutes rape in Sweden; and Assange getting full of himself to Trump-like proportions and letting that influence his behaviour with the ladies.
On the email, obviously a funny joke. There was some press coverage about zero point laser experiments a while back. The real issue regarding emails is that the secretary of state’s emails have been hacked because a nominee for Prez did not want her emails to be subject to normal government scrutiny and corresponded from a private server*, and the DNC emails show the attempted cover up**. This includes official corro with the President! Think yourself lucky you don’t have to vote in the US. The choices are worse than here. At least voting in the US isn’t compulsory.
*Our PM has done similar, again to avoid scrutiny. It should be stopped.
**i wonder if their defence will be " nobody suggested there wouldn’t be a cover up". Older kids will get the allusion.
