(CNN) In the most important sense, the Hanoi summit failed for a very simple reason: North Korea will not eliminate its nuclear arsenal over the next months or years. It is more important than ever that negotiations succeed in limiting the threat from a nuclear-armed North Korea. Pyongyang's conduct over the last year and decade should leave no doubt about its intention to retain its nuclear arsenal. The Hanoi summit failed to disarm North Korea because North Korea won't disarm. But in another sense, the summit failed because the Trump administration has maintained an inflexible insistence that immediate disarmament is the only acceptable outcome.
