The suggestion to send US troops to Mexico to fight drug cartels combines the worst features of the war on drugs and the war on terrorism. From Ron Paul at ronpaulinstitute.org:
The 50-year US war on drugs has been a total failure, with hundreds of billions of dollars flushed down the drain and our civil liberties whittled away fighting a war that cannot be won. The 20 year “war on terror” has likewise been a gigantic US government disaster: hundreds of billions wasted, civil liberties scorched, and a world far more dangerous than when this war was launched after 9/11.
So what to do about two of the greatest policy failures in US history? According to President Trump and many in Washington, the answer is to combine them!
Last week Trump declared that, in light of an attack last month on US tourists in Mexico, he would be designating Mexican drug cartels as foreign terrorist organizations. Asked if he would send in drones to attack targets in Mexico, he responded, “I don’t want to say what I’m going to do, but they will be designated.” The Mexican president was quick to pour cold water on the idea of US drones taking out Mexican targets, responding to Trump’s threats saying “cooperation, yes; interventionism, no.”
