The Government of Mexico, headed by President Claudia Sheinbaum, sent a diplomatic note to the United States requesting details about the installation of a military base on the common border.
The move comes in response to U.S. President Donald Trump’s recent authorization for the U.S. Army to take control of federal land in the border strip as part of his immigration policy.
U.S. decision

On April 11, 2025, President Trump signed a memorandum transferring control of the “Roosevelt Reserve.”
It is a strip approximately 18 meters wide that stretches across the states of California, Arizona and New Mexico, from the Department of the Interior to the Department of Defense.
This action allows the Army to establish a military base in the area, with the stated objective of strengthening border security and apprehending migrants crossing irregularly.
The measure has generated controversy, as it could contravene the Posse Comitatus Act of 1878.
It prohibits the use of the Army in law enforcement functions within U.S. territory without congressional authorization.
Legal experts anticipate that the decision could be challenged in court.
Response from the Mexican Government

In her morning conference on April 16, President Sheinbaum confirmed the sending of the diplomatic note.
He emphasized the importance of maintaining collaboration in security matters and respect for national sovereignty.

“We hope that it does not cross the border and that there will continue to be the same collaboration as there has been so far in terms of security,” said the president.
Sheinbaum also expressed that the Mexican government does not know at this time what tasks the U.S. Armed Forces will perform in those areas.
He expects them to be carried out respecting Mexican territory.
“We don’t know if it is to continue building the wall or what the objective would be, but in any case what we always ask for is respect and coordination,” he added.
Implications for Hispanics

The installation of a military base on the border and the tightening of immigration policies could have a significant impact on the Hispanic community residing in the United States.
Especially in areas close to the border.
Human rights organizations have expressed concern about the possible use of the Army in immigration control functions.
Also on the implications this could have for the civil rights of migrants.
The current situation underscores the importance of U.S.-Mexico diplomacy and cooperation to address shared security and migration challenges.
Respecting the human rights and sovereignty of both countries.
