Assange is not a US citizen. Meanwhile Bradley Manning was a US soldier releasing classified info.
Why are you comparing the two?
Assange is under no obligation to the US to not release stories that are embarrassing to the administration.
Secondly, the alleged "sexual assault" charges against him are trumped up and not actually sexual assault. If anybody bothered to look into it, it is obvious the charges are BS.
It's not even sexual assault, but rather "sex by surprise." Based on some archaic law from the 18th Century. For not using a condom during CONSENSUAL sex.
He had CONSENSUAL sex with a woman in Sweden and later on that night, he banged her again without a condom. The Swedish government was PRESSURED by the US to charge Assange only for QUESTIONING.
Sweden initially didn't think anything was there. And the woman involved in the case also didn't want to press any charges.
It's just the US politically pressuring Sweden to extradite him on this BS charge, so they can snatch him during transit. That's why he's still hiding in the embassy.
