Reminds me of another unknown “border dispute” I read about, where a Canadian psychologist was permanently barred from the US, because he wrote about taking LSD in the 1960s: https://www.wired.com/2007/04/canadian-psycho/
Which is odd because the northwest passage dispute is easily the most important one and the other 4 are just petty local bickering. The northwest passage dispute will ultimately be about international trade and that's as serious as any dispute can be. Maybe the author thinks the northwest passage dispute won't come to a head until a few years or decades when the passage clears of ice and becomes easily navigable by ships year-round.
A border war is in no way the same thing as a border dispute. Countries disagree or have ambigous borders all the time. That doesn't imply they declare war on eachother.
...and thank God. But if it was an issue of sea access or some other vital issue, war we would have. This will be settled one day by cooler, impartial heads and both sides will accept.
Looking at the map, it's amazing how far down Alaska goes...halfway to meeting US, mainland border.
Here's the area anyway: Dixon Entrance https://maps.app.goo.gl/F3AnJf6yKKJJxhiV8
