After a campaign of “sending rapists,” “deportation force,” “whip out that Mexican thing again,” and “bad hombres,” the Trump administration has moved from the theatrical to the practical in its first steps to build a new wall along the U.S.-Mexican border. Prior to the inauguration, President Donald Trump’s transition team approached the U.S. Army Corps of Engineers and the Interior Department about a new physical border. In his first week in office, Trump signed an executive order instructing the Department of Homeland Security to repair existing portions of the border fence and to build new sections as authorized by Congress in 2006. Although the new administration is clearly moving to fulfill its campaign promises, the results of a new physical barrier will likely have a counter-intuitive effect: Mexican drug cartels will grow stronger.
Since 2006, when the Mexican government declared war on the drug cartels, the United States has increased its law enforcement, military, and intelligence cooperation with its southern neighbor. With U.S. support, Mexican authorities have been able to kill or capture 33 out of the 37 most dangerous cartel leaders. The recent extradition of Joaquin “El Chapo” Guzman to the United States is a testament to the value of high-level cooperation between the two countries. As a result of these notable successes, several larger cartels have fractured and have descended into in-fighting.
