North Korea's nuclear test drew the usual reprimands from world leaders. President Obama promised swift and credible action. We know what this is likely to mean – more sanctions and greater isolation for Pyongyang.
But what if the answer should really be the opposite? What if the best way to change North Korea is more commerce and communication with it rather than less?
If you look at examples of how we deal with other countries, sanctions rarely work. In Cuba, 54 years of sanctions have kept the Castros in power while its citizens have suffered. They remain isolated with the lowest rate of Internet penetration in the entire western hemisphere.
