The United States has long used drone strikes to take out people it alleges are terrorists or insurgents. President Donald Trump has taken this tactic to new extremes, boasting about lethal strikes against alleged drug boats in the Caribbean and declaring the U.S. is in a "non-international armed conflict" with narcotics traffickers. Trump appears to be merging the war on terror with the war on drugs. This comes as he's simultaneously ramping up the use of troops to police inside American cities. The modern drug war began during President Richard Nixon's administration. In 1994, the journalist Dan Baum tracked down Nixon aide John Ehrlichman and interviewed him. He said, "Look. The Nixon campaign in '68 and the Nixon White House had two enemies: Black people and the antiwar left. [V]ilify them night after night on the evening news, and we thought if we can associate heroin with Black people in the public mind and marijuana with the hippies this would be perfect." And [Ehrlichman] said, "Did we know we were lying about the drugs? Of course we did." This line of thinking drove policies designed to "unleash" law enforcement. The Nixon administration tried to relax wiretapping laws, roll back Miranda rights, and erode Fourth Amendment protections against unconstitutional searches and seizures. And now we're seeing the Trump administration push even harder to roll back constitutional protections.
