"No one will come here to tread our laws," he continues. "No one will come here to trample our country on our land."
Mexico, they claim, actually built the border wall of US President Donald Trump after all – not with concrete or bricks or steel, and with thousands of federal forces like this camouflage-clad commander and troops carrying out his orders.
And Mexico, they claim, pays for it.
Trump: "Mexico shows us great respect"  Yes, US taxpayers support the bill for efforts to build new physical barriers on the US-Mexico border.
A few days later, Trump told reporters that he was "using Mexico to protect our border," because Democrats were not doing enough to fix the immigration system.
"Mexico's Enhanced Border Security efforts along their southern border continue to have a dramatic impact on this regional crisis," he writes. "I just came back from Mexico where we had discussions to work together to stop the flow of illegal migration throughout the region.
Not everyone praises enhanced cooperation.
A recent video of the response of the National Guard to the caravan of migrants from Central America and Africa has sparked a backlash on social media.
"True: President Trump uses Mexico. And against all logic, Mexico is letting him get away with it, "he writes." That has to change. "
Thousands of servicemen are deployed
asked to respond to claims that Mexico is effectively paying for the wall Trump wants, Foreign Ministry spokesman Roberto Velasco told CNN that migration flows have declined significantly in recent months and that efforts are continuing for a regional development plan to address the root causes of migration in Mexico, El Salvador, Guatemala and Honduras.
"B. the migrant population represented by Mexican authorities has declined by 70% from June to September, "he said.
Lopez Obrador said there was no other choice but to negotiate.
Nearly 15,000 troops have been deployed to Mexico's northern border, where they have set up 20 checkpoints, Mexican Defense Minister Luis Cresenzo Sandoval said at a news conference last week on the country's security strategy. , 12,000 troops are stationed on the southern border and have installed 21 checkpoints.
Military helicopters regularly conduct air reconnaissance in the two border areas, he said. So far, Cresenzio said, more than 60,000 migrants have been captured as part of the effort.
At the same press conference, staff noted that the number Asylum seekers in Mexico have increased dramatically, with about 80,000 asylum applications expected by the end of this year.
The Earth Message
Analysts told CNN a video of efforts by the Mexican authorities to block a recent caravan is a revealing window on how changes in Mexico's policies unfold.
"The message is that Mexico is not interested in protecting people in need," says Gretchen Kuhner, director of the Institute for Women in Migration, a Mexican advocacy organization. "The message given by this general is not the official message of the government, but it explains very well what the message is on the ground."
Ana Maria Salazar, a former US deputy deputy secretary of defense who is now based in a security analyst in Mexico, says the images of the operation illustrate the concerns of critics when the Mexican National Guard was formed and deployed this year. .
"This is someone who is trained to defend national sovereignty, not someone who deals with migrants. And that is the concern of forming a National Guard so quickly, "she said." You cannot expect that from one day to the next, a soldier trained to defend the territory from enemies of the state will now be responsible for people who are trying. to cross illegally in the country. These are very different missions and this affects the images and what the commander says. "
way, Salazar says, Lopez Obrador is bidding on Trump when it comes to processing his government's migrants, such a rigorous implementation of immigration along Mexico's southern border has not been observed so far, she adds.
But Salazar says that Lopez Obrador, unlike his predecessors, has "so much credibility in Mexico that it can assume political is the cost of that decision. "
In the past, in her opinion, presidents would have been attacked for taking such steps and international pressure would increase.
"This pressure that was exerted on former Mexican governments, she says," is extremely tacit about this government's decisions. "
In fact, public opinion about migrants in Mexico also seems to be changing.
A survey conducted by the Washington Post and Mexican Reforma in the summer showed a significant proportion of Mexicans who believe that increased migration through Central American countries is a burden on Mexico's economy and services. Just over half prefer to deport more migrants.
