Where have you been these past 20 or so years?
Since when has a nation’s prerogatives - independence, sovereignty, etc - been upheld by this country or anyone else. Not since the NWO decided that invading and holding and arresting and charging and imprisoning was the right of everyone else except the country in question.
No - Julie is safe as long as this administration holds the reins. Or as long as he continues to serve a useful purpose.
Your argument falls flat...very flat.
Assange has not been arrested yet because he's been able to leverage the knowledge that he has more docs to dump along side the fact that he is not legally obliged to U.S. laws outside of the U.S. Even though we do regularly violate the sovereignty of other nations, we usually do so with at least a modicum of caution so as not to end up with egg all over our face. Sometimes it ends up there anyway. But my point is right now, Assange is far too public and still has too many cards against our government to make the violation of Australian sovereignty to arrest him a viable option at this time.
