I think Assange wants his life back with some hope of not being poloniumed or worse. He will work with whoever will give him the most hope. He is in exile and may be discovering as “the man without a country” that America is still the best nation on Earth to be a part of.
Is he a reformed man and a true libertarian and capitalist convert now, probably not. But in America if you come clean and make legit amends, we are a forgiving nation. Best to work with Q and POTUS even if it means some penance.
Julian Assange became an Ecuadorian Citizen last month. The only reason he is still in UK is there is warrant for his arrest, that needs to be thrown out, so he can leave embassy. Here is some current info:
