Good afternoon to both of you.
Professor Charron, let me start with you. You've written extensively on Arctic sovereignty, and there's something that I'm hoping you can define for me or elaborate on to help me understand more.
You talked about previous history and you talked about sovereignty, and about de facto being a better definition than de jure. Now you've reversed that, saying that de jure today is more important than de facto. Can you explain that in terms of Arctic sovereignty?
