When the now president of the United States, Joseph Biden, offered to move away from the restrictive and inhumane policies of his predecessor, Donald Trump, against undocumented migrants at the border with Mexico, many thought that more clement times would come for these people.

It was a big mistake because things did not turn out that way and it was clear from the first days of the new head of the White House, when he warned in an emphatic manner "Do not come", which was later ratified by Vice President Kamala Harris, in charge of the issue in this administration.

This had already been warned by the neoconservative writer Robert Kaplan, who before the 2020 elections assured that, "even if Joseph Biden is elected president in November, we will not return to the world before Donald Trump".

The author was referring to the strained relations his country maintains with China, but the warning has not only worked there, but also on the issue of migratory flows coming from the south.

Biden maintains several measures, among them the immediate expulsion of those who are captured in his territory and the "stay in Mexico" program, both with the justification of the health crisis created by covid-19.

Likewise, patrols were increased and the difficulties that drive migrants to seek more dangerous routes, where many have lost their lives, as shown by the statistics on the number of deaths.

The latest novelty is not to be missed and is the use of robot dogs to guard precisely the most inhospitable places, where hundreds of desperate people, many accompanied by their families, are trying to pass through.

This equipment, created by the Science and Technology Directorate of the Department of Homeland Security, has already been tested in the most difficult terrain, such as the desert, very humid areas, with high or low temperatures and places with little oxygen.

They are equipped with different cameras and sensors to detect movements or chemical, radiological and biological signals. They can also walk through places built by humans, such as staircases or check the underside of vehicles or train carriages.

The new kind of cybernetic "firulais" can protect the lives and safety of border police, but not those seeking to enter the "capitalist paradise" to escape poverty, violence or disease.

It is not known when these machines will be put into operation, but neither will they stop migration because suffering does not know about waiting or deadlines and encourages those who have nothing more to lose.
