Answer: If considering an island within the United States for exiling a president in a hypothetical scenario where the Napoleonic emperor concept is skipped, several islands might be considered based on their remoteness and size.
Midway Atoll: Located in the North Pacific Ocean, Midway Atoll is a remote, unorganized, unincorporated territory of the United States. This option offers isolation with limited human habitation and infrastructure.
Johnston Atoll: Situated in the Pacific, this uninhabited island is also a U.S. territory. It has a history as a location for testing and storage of chemical weapons, and its remote location would provide ample isolation.
Wake Island: Another remote atoll, Wake Island is part of the U.S. Minor Outlying Islands. Its isolation makes it suitable for this purpose.
Palmyra Atoll: This atoll is privately owned but is administered by the U.S. Fish and Wildlife Service and is part of the U.S. Minor Outlying Islands. It’s uninhabited except for occasional scientific research staff, making it another contender.
These islands were often used historically for military or scientific purposes, providing the isolation and minimal infrastructure that might be sought in such a hypothetical situation. These locations would serve the necessity for remoteness while remaining under U.S. jurisdiction.
