While North Korea is seemingly moving towards reconciliation with America and South Korea, the US is right to mistrust the regime that has repeatedly broken its word and to show deterrence, asserts Stephen Collinson of CNN. It might be offering an olive branch right now because its nuclear development is so advanced that no further missile tests will be needed. The renewal of dialogue could also be an underhanded effort to divide the US and South Korea over their preferred approaches to the regime. North Korea might be using this dialogue to give itself breathing space after recent sanctions that were particularly isolating. Deterrence is best.
