What is the nickname of the pseudo-confrontation between Denmark and Canada over Hans Island?

The Whisky War (also known as Liquor wars) is a pseudo-confrontation and border conflict between Denmark and Canada over Hans Island. Since the 1930s, Hans Island has been in the middle of a disagreement between the two nations.

Hans Island is in the middle of the Kennedy Channel between Greenland and Ellesmere Island. A theoretical line in the middle of the strait goes through the island. Canada and Denmark could not come to terms on Hans Island in 1973 when a border treaty was signed, leaving a gap in its border description.

In 1984, Canada provoked Denmark by planting its flag on the island and leaving a bottle of Canadian whisky.The Danish Minister of Greenland Affairs came to the island himself the same year with the Danish flag, a bottle of schnapps, and a letter stating "Welcome to the Danish Island".
