He actually has a pretty consistent agenda - reveal shocking stuff that people don't want revealed, and do it with a dramatic flair. Yes, a couple years back his releases on Iraq / Afghanistan had some things that enraged Republicans and were praised by Democrats. Now he's exposing their house.
He's an agent of chaos with a self promotion streak. Saying his agenda is anything beyond that ignores history.
I'm not a big fan, but I think endangering the non-decision makers is bad.
Although I'm not sure if that is because the majority of the documents he gets are from the US, or if the US has been, and always will be, a place where secrets are so tightly guarded anybody that has an avenue to expose some of them are going to do so.
Does Wikileaks get documents from other countries? Has he gotten the amount of publicity in other countries from those leaks that he has on his US documents?
Backtrack a few years ago, and it was the Republicans and all their supporters who wanted to tar and feather Assange for the Snowden leaks. Hannity talked about how Assange should be in jail and all the crimes he committed against the US intelligence community, got CIA people killed and on and on and on.
It's clear it depends on who's OX is being gored with Assange, which makes him a unique personality to deal with. I don't think he picks sides, he just always picks the publicity angle and doesn't really care who gets in the line of fire. The funny part is how each side treats him like a savior or some kind of patriot but then when he gets leaked documents on their side, suddenly he's the bad guy?
I just don't like him period, but he does have a flair the dramatic doesn't he?
