This is not correct. Sweden has very close intelligence and diplomatic ties with the US. It even provides US diplomatic services in some countries where the US doesn't have a presence, one example being North Korea.
Of course they do. Sweden is far from God and close to Russia.
Sweden dropped the charges, and the presumption is it was a matter of clearing the path for his release because it is inconvenient for all parties involved, except Assange, but mostly for Ecuador.
If you're an Assange stan, you probably have picked out the parts where the media is upset because 1st Amendment! The 1st Amendment doesn't cover breaking the law, ie assisting a potential leaker break into a safe, carrying out a briefcase or assisting in covering cyber tracks of password tampering. Other parts of the media have covered that, and if there's a trial, the lawyers need to tread carefully (as would the judge) if the 1st Amendment is to be preserved. (Yes, there are issues there).
As for the politics, most "Resisters" are angry at Obama for failing to notify the country about the depth of Putin's efforts to elect Trump. They have also noted that Trump loved WL in 2016, and that Roger Stone was his bestest bud.
Some people can walk and chew gum at the same time.
There is no guarantee extradition will be granted. No guarantee it will not. The charge is for 5 years maximum, the death penalty is not involved, and this has always seemed to me to be one of those great spy conspiracy stories where people will be embarrassed about the position they took later.
