One of President Donald Trump’s strategies for enticing North Korean leader Kim Jong Un into sweeping talks about scrapping his country’s nuclear arsenal has been to dangle an apparently unlikely promise of future prosperity. Kim’s poverty-stricken country, Trump said at a White House meeting last month, could end up “very rich.” Is this just more Trumpian hyperbole, or is the president on to something? At Foreign Policy, Stephan Haggard surveys arguments he and Marcus Noland have made for a long time about the possible path of reform for North Korea. The key issue: As a small and increasingly open economy, the external sector will loom large in any reform process. The implication: A trade involving security assurances and sanctions relief for denuclearization is not implausible.
