The Spin

Narrative A

Machias Seal Island rightfully belongs to the U.S. as per the Treaty of Paris of 1783, which granted sovereignty over all islands within roughly 70 miles of the U.S. coastline. Not only does this island sit well within this boundary, but the U.S. claim was also validated by arbitration under the Treaty of Ghent and remains firmly grounded in international law.

Narrative B

Canada's sovereignty over Machias Seal Island is absolute. However, the country continues to issue permits to American tour operators that openly market the island as part of Maine. This issue requires urgent correction, which is why the DFO must be willing to revoke the Bold Coast Charter Company's permit if it refuses to acknowledge Canada's rightful ownership of the island.

Metaculus Prediction

There is a 4% chance that the U.S. will annex any part of Canada before June 3, 2072, according to the Metaculus prediction community.
