Overview

• President Donald Trump signed an executive order renaming the Gulf of Mexico to the Gulf of America and Denali in Alaska to Mount McKinley, fulfilling a campaign promise.
• The U.S. Interior Department announced that these changes will apply to official U.S. federal usage, but other countries and international organizations are not obligated to adopt them.
• The Gulf of Mexico borders Mexico and Cuba, and their acceptance of the name change remains uncertain; Mexico's President Claudia Sheinbaum emphasized the importance of official documentation over verbal declarations.
• The renaming of Denali reverses a 2015 decision by the Obama administration, which restored the mountain's indigenous name, a move Trump's administration criticized as an affront to President William McKinley.
• Observers note that such unilateral geographic renaming could lead to diplomatic tensions, as seen in similar disputes involving other international bodies of water.
