There's a part of the U.S. that you can only get to through Canada.

 

Canada finally resolved a border dispute with Denmark in 2022.

 

 

 

Hans Island is a 0.5-square-mile landmass that lies 11 miles off the coast of both the Canadian territory of Nunavut and northwestern Greenland, in the Nares Strait. Although this barren rock sports no vegetation, it was nonetheless at the center of a 50-year-long border dispute between Canada and Greenland, which is an autonomous territory of Denmark. The disagreement began in 1973 when the countries met to settle disputes along the Nares Strait. Hans Island became a point of contention, so the officials decided to discern its status at a later date. But that decision came to a head in 1984 when Canadian troops stuck a maple leaf flag on the rock and buried a bottle of the country’s finest whisky there. A few weeks later, Denmark responded to this provocation with a flag planting and a schnapps-burying ceremony of its own. This bit of friendly back-and-forth became known as the “Whisky Wars,” and the battle “raged” for nearly 50 years (at worst, maybe some feelings were hurt). Finally, in June 2022, the two countries settled amicably, with Canada taking ownership of roughly 40% of the island while the Danes took the remaining 60%. The agreement was sealed with a ceremonial exchange of liquor bottles. The Whisky Wars officially ended, and now Canada and Denmark enjoy the world’s longest maritime border — conflict-free.
