1. Sweden extraditing Assange would be extremely difficult because they'd have to sign off on it, and so would the UK. Neither have suggested they would.
2. Manning was in solitary, not tortured.
3. The UCMJ places more restrictions on you. Members of the military are basically held to a higher standard and have FEWER rights than others. For example, you can face a court martial and a separate criminal trial and double-jeopardy does not apply. This was explained to me that I was effectively waiving some of my rights when I joined the Marine Corps. Bradley Manning voluntarily made that choice.
4. You're suggesting that the UK and Sweden have both been duped and Ecuador has proof of this. But said proof hasn't been revealed publicly. If Assange had any proof he was framed, why wouldn't he reveal it?
5. Agiza was an Egyptian wanted in Egypt that Sweden handed back to Egypt. Sweden had negotiated promises from Egypt that he would not be tortured, and Egypt lied. Sweden had also labeled Agiza a terrorist, which it has not done to Assange. Sweden ruled that letting Agiza in the country was a security risk because they labeled him a terrorist, and thusly deported him to his home country, while at the same time demanding that Egypt not torture him. Sweden had zero qualms letting Assange in the country. Saying this situation is the same is nothing short of ridiculous. They are completely different.
6. This is by far the most important point. Conspiracy theorists assume that anyone who speaks negatively of the US government is rounded up and punished for it, but all evidence speaks to the contrary. Plenty of Americans speak out negatively about the government every single day with nothing happening to them.
Again, there is zero documented evidence that he was framed. There is zero documented evidence that Sweden would be able to or willing to extradite to the US for someone they haven't gone after themselves.
