Can Donald Trump really rename the Gulf of Mexico the 'Gulf of America' or does he need to just, like, chill?

Contributing sentiments towards policy:

53% : Its lengthy legacy clearly means very little to Trump, however, and his threat does have some weight behind it -- though it comes with a catch.
45% : Treaties can take years to hammer out, even when the best negotiators are involved, and Mexico's president, Claudia Sheinbaum, has already made it clear she isn't looking to make friends with Trump.
43% : Trump has the power to change part of the Gulf's name, but he couldn't rename the whole thing.
42% : After weeks of harassing Canada, Mexico, and Greenland over his supposed intentions to annex the various U.S.-allied countries, mind you, Trump has decided that the Gulf of Mexico should be a part of the conversation.
35% : Americans would have to buy new maps -- I'm sure Trump will sell some special edition versions plastered with his name -- but the idea comes across as a vanity project, roughly as serious as the early 2000s cries of "freedom fries."
