Absolutely. Assange is facing up to 175 years in solitary confinement and could not possibly get a fair trial in the US. Moreover, He has been illegally recorded and spied upon for the past 7 years by the CIA, including conversations with his lawyer. A case can hardly get more politically motivated than this. He even received death threats from US politicians in the past. It would be ridiculous to extradite anyone under such conditions.

We do as we are told to do (and there's something in the English character that likes it like that). Current Prime Minister is an American (renounced his citizenship in 2016 after a large tax bill) and there are many other unquestioning free-market cultists here: see Brexit for further examples.
