What is braindead about it? Sweden and other EU countries are extremely hesitant when it comes to extradition based on "political crimes", therefore the US prosecutors already changed the inducement to computer fraud etc.
I live in a EU country where our government looks the other way when our citizens are being illegally detained by the CIA. There is at least one case where one of our citizens was tortured for years w/o court date.
When the US found out that he was not a terrorist, they asked our foreign minister what should happen to him. He told them to keep him, so he was tortured for a couple more years.
The whole world looked the other way when the US forced down a diplomatic plane to search for Snowden.
Chelsea Manning was sentenced to a life in prison under circumstances that can't be called due process.
What is so outlandish about thinking that Assange would be extradited?
Sweden also has a history of, in violation of Swedish law and international treaties, black bagging political asylum seekers and handing them over to CIA to have them shipped off to be tortured. Years later Swedish military intelligence uncovered that CIA rendition flights via Sweden were still ungoing.
Conveniently we know of the latter thanks to Wikileaks, seeing as the Swedish government kept quiet about it.
I don't think Assange's case is a US conspiracy, but I also am not that surprised if Assange does genuinely believe it, and the bizarre behaviour of the Swedish prosecutor (which my personal theory is down to domestic politics - both the prosecutor and the appointed attorney for the women have a history of pushing for radical tightening of the application of Swedish laws on rape and sexual abuse) certainly would give him more reason to hold on to such a belief.
Putdowns of the rest of the community are particularly tedious.
