The US has a new ambassador to Mexico.

He will be the ambassador of intelligence.

On Tuesday, he was sworn in under the U.S. Constitution with Vice President J.D. Vance as his witness. This is Ronald Douglas Johnson , the U.S. ambassador to Mexico.

Married to Cuban Alina Arias, the ambassador will arrive in Mexico City in the coming hours. The couple has four children and eight grandchildren.

Those who know the couple have told me that Alina Arias has enormous influence over her husband. She, a Cuban nurse by profession, reminds me of the decision President Trump made under Marco Rubio's influence: to revoke visas for officials who have hired doctors exploited by the dictatorship.

In Mexico, no attention was paid to it. Particularly at the National Palace, the issue wasn't mentioned, nor did the secretary general of Morena, who claims that Cuba has a democratic political system.

Ron Johnson spent nearly 50 years of his working life between the Army and the CIA.

Only readers over 40 will remember the civil war in El Salvador. Johnson was one of 55 military advisors who prepared combat and counterintelligence strategies against the Farabundo Martí Front (FMLN).

Ron Johnson was selected as the first Special Forces officer to train as a CIA operative through a scholarship from the Army War College, serving as a key link between the intelligence community and the U.S. Southern Command.

He has carried out covert operations in the Latin American region.

The name Pablo Escobar is not unfamiliar to Ron Johnson. Nor is that of Karadic, a Serbian war criminal. The US ambassador to Mexico participated in intelligence operations to hunt down both men.

If the medium is the message, the ambassador is the answer for President Donald Trump.

The president has chosen him to assist him on border security, migration control, and the fight against fentanyl.

The relationship between Johnson and President Bukele is excellent. The American served as ambassador to El Salvador when the security situation was out of control.

Regarding trade, Trump will be directly in charge. The novelty of the USMCA is security.

The topic will become a meta-agenda.

The new State Department officials don't understand how AMLO manipulated Ambassador Ken Salazar; they also don't understand the conditions the Mexican imposed on Joe Biden, particularly his reluctance to cooperate on security issues.

They think the "hugs, not bullets" policy is a bad joke, but what they can't tolerate is the "pause" AMLO gave Ambassador Salazar.

The dynamic will be different. President Trump's administration knows that the security of the United States is intertwined with that of Mexico, and on this side of the border, the state has been losing control of its territory day by day.

The National Palace's love for Latin American dictatorships is a key issue for Rubio. Strategic US decisions against them will be forthcoming. In fact, they are already underway.

This is the environment of Mexico and Ron Johnson. He doesn't wear a hat like Salazar, but he is a green beret.
