He isn’t a journalist, he’s a hacker. He didn’t seek political asylum, he jumped bail over a rape case. He is (rightly) now in jail.
If he is sent to Sweden to face the charges of rape, then yes.
But should he be sent to the US there is no criminal case other than hacking and whistle-blowing or as the charges may read: Treason.
Then of course we can argue whether it is treason to call out corruption in your country..
He cannot be charged for treason in the USA as he is not a citizen.
It is most likely that when they get him to the USA additional charges will be tacked on to the current hacking charge.
Whatever we think of this man personally what is happening right now is not justice, it is the international security and military establishment led by the US getting revenge on the man who showed them for what they are.
But the most frightening thing is not this case but the next case. When the next whistle-blower who isn't as well known or a dissident is fleeing persecution and can easily be dragged back to face certain death or torture in their home country now that this case has paved the way.
