And Swedish military intelligence uncovered Swedish staff complicit in ongoing rendition flights via Sweden
years after the black-bagging incident had caused the government to formally protest about it.
We know this only because Wikileaks leaked cables from the US embassy after they were called in for the Swedish government to object that this continued to happen even without the governments knowledge.
So one thing is what the Swedish government itself would be complicit with. Another is whether the US cares and whether the Swedish government would have the power to stop it.
Personally my pet theory is that the Swedish charges were not something that happened with US involvement, but an overzealous prosecutor, but that there were enough iffy things going on that I understand why Assange would fear being sent there - that fear does not need to be justified to be real.
But I also know that as someone living in the UK, even with the kangaroo court Assange is currently subject to, I'd far prefer to face an extradition hearing in the UK to Sweden, because even in the face of this I wouldn't trust the Swedish government to be able or willing to resist as much as the UK government.
