My personal prediction:
It is pretty obvious that the US government has no special interest in an early conviction. They just want to hunt Julian Assange down and torture him for the rest of his life. And there sure are plenty of mentally deranged psychos on the CIA payroll who are more than willing to and take great delight in skillfully exercising this task.
If he is found guilty, a lot of people will accuse the US government of disregarding the freedom of press.
If he is not or only partially found guilty, the US government might be considered weak and send a wrong signal to all future whistleblowers.
So why would the US government be in a hurry for a fair trial that the whole world will be watching closely? Slowly cook him to death surely is the more gruesome alternative.
