Milton Friedman, 1998

"Our drug policy has led to thousands of deaths and enormous loss of wealth in countries like Colombia, Peru and Mexico, and has undermined the stability of their governments. All because we cannot enforce our laws at home. If we did, there would be no market for imported drugs. There would be no Cali cartel. The foreign countries would not have to suffer the loss of sovereignty involved in letting our advisers and troops operate on their soil, search their vessels and encourage local militaries to shoot down their planes. They could run their own affairs, and we, in turn, could avoid the diversion of military forces from their proper function."
