Basically every country that he can probably go to under the conditions he made (medical), without rousing suspicion, has an extradition treaty with the USA. Certainly if he wanted to go to Afghanistan for "epilepsy treatment", it'd be weird, right?

Which one's good? If you really cared about the extradition treaty so much, you'd have a problem going anywhere (given his situation, and I think even for the typical tourist most countries on that list are countries you might not even ever think about visiting. Though I've admittedly visit quite a few of those, so I may be wrong on that point).
