That sure went quick. If you blinked, you might have missed the historic summit between President Trump and North Korean dictator Kim Jong Un. The two leaders met privately, save for interpreters, for less than an hour, and by the afternoon were signing a statement that promised security guarantees from the United States and complete denuclearization by North Korea. What does it mean? On one level, very little. Observers have noted that North Korea has been promising complete denuclearization for over 25 years, a promise which has done nothing to impede it from building a growing nuclear arsenal and an increasingly sophisticated array of delivery vehicles. A mere reiteration of that promise, with no agreement at all on timetables or verification measures or anything else is worth very little in its own right.
