US President Donald Trump has declared that the Gulf of Mexico will now be called the 'Gulf of America' in an executive order signed after his return to the White House. Trump referred to the water body as an 'indelible part of America' and critical to US oil production, fishing, tourism, and recreation. However, the move has been criticized as 'very silly' and likely to be ignored by maritime professionals. Mexican President Claudia Sheinbaum has suggested calling the United States 'Mexican America' in response to the renaming. The International Hydrographic Organization and the United Nations have expert groups on geographical names, which may address the issue in their upcoming meetings.
