I think many people would agree that there is more involved than sexual criminal charges made against Assange in Sweden ; serious as they are.
His organization hacked into and posted thousands of secret emails on the web.
Step 1 for the USA to get hold of him and bring him to justice is to get him extradited to Sweden and tried and after sentencing nab him which rightly I believe is the ultimate goal.
The circumstances that have developed between the United Kingdom and Ecuador are over this devious Australian.
Sweden asked Britain for his extradition to face criminal sexual charges there. An extradition hearing was held and the judgement was that Assange should be extradited. Like all low-life he appealed and after losing the hearing jumped bail and holed up in the Ecuadorian Embassy in London.
A diplomatic spat has ensued with the British government requesting the Ecuadorian Embassy to hand Assange over so that he can be deported. The Ecuadorian government have refused and granted Assange political asylum.
The result is an impasse. If Ecuador bring him out of the embassy Assange will immediately be arrested and handed over to Swedish authority by the British in line with the extradition agreement they have with Sweden.
I see the Ecuadorian action as a clumsy undiplomatic decision taken primarily not against Sweden, but against the United States government.
Quite rightly the US want Assange to answer for the untold damage he did by posting thousands of top secret documents on the internet.
It seems on the face of it that the Ecuadorian government are being anti-American in their attitude and that does not bode well for the future.
