Or should the passage be considered international waters, open to everyone and owned by no one? In former U.S. Ambassador to Canada Paul Cellucci’s view, there’s no contest. After 9/11, anarchy is not an option.”
This issue becomes more important with global warming thinning out ice cover and making the waterway more navigable.
