You just do not get it. Whether it is a dumb law or not, he broke it and it was a really stupid thing to do. Who-ever gives him legal advice should be jail with him.
Just because I do not agree with your view on Jules is neither dishonest or disingenuous. Manning is a whistle-blower, who broke US Laws and is paying for it. Jules encouraged him to do it, breaking US Law, and then posted every scrap without any vetting or work that a real journalist would, again breaking Laws of many Countries, maybe including Australia. If he was justified in doing this in any way, due to the Public Good, then let him have his day in Court to prove it.
And I do not subscribe to the theory that the USA, UK and Australian Governments are corrupt and full of liars, cheats and thieves. If I believe all I read in the papers and watch on TV, then there is no doubt that some of Government arms go beyond their legal rights and they should be bought to account. Whistle-blowers have paths to lodge their agendas without causing harm to others, and there are many reputable media organisations across the world that would have taken all of Mannings docs, vetted them carefully and then went after the corrupt.
Maybe this view is authoritarian, but I believe in centralised Government with total control. I may live in a democracy and been part of a democratic political Party for 48 years but I have no faith in democracy, little faith in “small” government and no faith in capitalism.
The right wing leaders you mention are not very nice people, and you can add many others to that from across the political spectrum. Most, if not all were elected under a democratic system and all have done some very poor things. Being authoritarian doesn’t mean you have to be corrupt or evil, and if I was the benevolent dictator Manning and Assange would have a chance to prove their worth, before I shot them.
