"The Canadian-Denmark Whisky War was probably the most polite war ever. It involved a small island off the coast of Greenland. The Canadians claimed it by putting the Canadian flag and bottles of Canadian whiskey on the rock, and the Danes would replace it with schnapps and the Danish flag. Both sides reached an agreement to split the island in 2022. I’m guessing this is more well known to Canadians and Danes than some of the rest of us."
