The administration of Donald Trump announced that the border wall with Mexico is being painted black to absorb heat and become virtually impossible to climb, in a new measure aimed at curbing illegal crossings.
Kristi Noem, Secretary of Homeland Security, confirmed this Wednesday that the initiative responds to direct instructions from President Donald Trump.
“This wall is part of the divide. Too high to climb. Too narrow to pass through. And now, following the president's instructions, it will be painted black, so hot to the touch that illegal immigrant criminals won't even try,” he stated.
The project is part of the measures to strengthen the border which, according to the government, have allowed for the reversal of what it described as "the worst border crisis in history."
"Today, that crisis is not only under control, but has been eradicated," Noem stated.
In addition to its practical function, the wall is presented as a political symbol. “It is both a shield and a symbol: a monument to the unwavering commitment of President Trump to this country and to the safety of the American people,” the official emphasized.
The decision has drawn criticism from human rights organizations and opposition sectors, who denounce the measure as an inhumane strategy that prioritizes physical deterrence over structural solutions to the migration phenomenon.
Meanwhile, authorities assure that the black paint will be applied gradually in several sections of the border fence, which will add another layer of difficulty for those attempting to cross irregularly from Mexico into the United States.
After assuming the presidency in January, Donald Trump restarted the construction of the border wall in Texas as part of his commitment to halt illegal immigration.
Despite the increase in costs, Trump believed that the wall is necessary to strengthen border security and fulfill his campaign promises.
With the proposed law, dubbed by the president as "the big and beautiful," funds were increased to strengthen border control and complete the construction of the wall.
Kristi Noem herself assured that there would be more money to complete the project "with cutting-edge technology," without initially specifying what it entailed.
Since then, long stretches have been completed to continue slowing the influx of illegal immigrants through that route.
