President-elect Donald Trump is once again considering a major, long-term global move ahead of his next term in office – such as the “absolute necessity” of the US purchasing Greenland.

Now Trump is tossing around the idea of ​​turning the Gulf of Mexico into the “Gulf of America.”

The nations with the most “control” of the Gulf are the United States, Mexico and Cuba, which have shared the waters for years. The Gulf serves as a major economic center, including fishing, power generation and shipping.

Why is the Gulf named Mexico? This is actually not a reference to the modern state of Mexico, but rather a Native American city that shares the same nickname and has had that name for more than 400 years.

Despite the fact that the Gulf is shared by multiple nations, Trump recently said that the U.S. does “most of the work” on the Gulf and insisted that the body of water should bear America’s name “because it’s ours.”

While ownership is up for debate, it is true that the US has claimed control of much of the Gulf. The United Nations Convention on the Law of the Sea established that U.S. territorial waters extend 12 nautical miles from its coasts and that the U.S. federal government also manages the seas and the flooded portions of the Outer Continental Shelf.

As is typical of some of Trump’s proclamations, he offered no technical details about how he might achieve the name change, postponing implementation of the name until “an early date in the future.”

Trump ally Congresswoman Marjorie Taylor Greene said she plans to introduce legislation Thursday to change the Gulf’s name.

“The American people are footing the bill for protecting and securing maritime waterways for commerce. “Our U.S. forces protect the area from any foreign military threats,” she said in a statement. “It’s our divide. The correct name is the Gulf of America and the whole world should call it that.”

While the US could pass laws requiring a name change in the US, there would be nothing that would force other nations to comply with this decision.

Trump also used his deliberations to attack Mexico, calling the country “very dangerous” and “in great trouble,” citing drug trafficking and illegal immigration. However, the majority of drug trafficking from Mexico is aimed at meeting American consumer demand.

Trump has also proposed imposing tariffs on both Mexico and Canada if the countries do not meet his demands to stop illegal immigration and curb drug trafficking. He claimed that America’s neighbors were responsible for significant amounts of drug and illegal immigration crossings, but provided no data or evidence to support his claims.

If Mexican President Claudia Sheinbaum Pardo is taking Trump’s threats to rename the Gulf seriously, she hasn’t shown it publicly. But she has responded to his threats to impose tariffs, telling the former president that cartel violence in Mexico — and the instability it causes — is driven by American demand for illegal drugs and U.S.-made weapons smuggled into the country , is heated.

Trump has suggested possible U.S. military operations in Mexico to crack down on drug cartels, said he would call Mexican drug cartels “terrorist organizations,” and elsewhere in Central America he has accused Panama of overcharging U.S. shipping vessels for use of the Panama Canal.
