Assange is an Australian citizen, who was never in the US military, who published online the US secrets Manning stole. IF he'd only also go transgender, he could get off with a slap on the wrist - .
After Manning told Assange that he doesn’t have any more secret data Assange urged Manning to continue committing crimes and promised assistance in breaking further into the DoD computer systems. It doesn’t say it exactly in the indictment, but it seems to me Assange then trained and advised Manning in computer hacking techniques, that resulted in Manning being able to steal hash values of passwords of other people in that location, that Assange attempted to crack, but as far as we know it wasn’t unsuccessful.
