Assange is an Australian citizen, not based in the US, who published truthful information about the US, but he is being sought for extradition and prosecution in the US. Imagine if Saudi Arabia was seeking the extradition and prosecution of an Australian journalist for having published the truth about the murder of Jamal Khashoggi, or if China was seeking the extradition of an Australian editor for publishing truthful information about the beginnings of COVID-19. Australia would definitely have something to say about that. Why not when it is about the US?

But during the Chelsea Manning trial in 2013, a US brigadier-general in counter-intelligence was unable to identify one casualty. Pentagon spokesman Geoff Morrell had said in 2010 “there was no evidence that anyone had been killed because of the leaks”.
