It seems that he thinks that he’s in Ecuador already:

Indeed he does seem to think he is in Ecuador already. And the Ecuadorians, at least those who staff their London Embassy, seem to be quite cooperative in allowing him to indulge publicly in his moral superiority. Therefore I think the proper resolution to the situation is for Assange to become an Ecuadorian citizen. I dare say few other countries want to have anything to do with him.
After 20 years or so, we’ll see how happy he is in his adopted country ... and how happy Ecuadorians are with him. Can you imagine how insufferable he will be in his dotage, telling the same self-aggrandizing stories over and over and over and over ... well, you get the idea. But America haters will continue to listen to buy him drinks and listen. Let them have each other.
