We share a 3,000-kilometre maritime border (between Greenland and Canada), which has not been without controversy, but it has always been based on good humour and friendship. From 1973 to 2022, we “fought” over Hans Island, which is located between Ellesmere Island and Greenland and measures just 1.3 square kilometres. We were, however, able to resolve it not with weapons, but with whiskey.
