Remember that time in the 90s when N.K. agreed to freeze its nuclear program? That was AWESOME.
North Korea first announced its intention to withdraw from the Nuclear Non-Proliferation Treaty (NPT) in 1992, and two years later the U.S. and North Korea signed the Agreed Framework. North Korea agreed to freeze its nuclear program, dismantle its graphite-moderated reactors and remain a member of the NPT. In exchange, the U.S. agreed to deliver fuel to North Korea while Pyongyang built light-water reactors for its civil nuclear power program and begin talks for diplomatic normalization between the two countries.
But the agreement broke down in 2003 when, following the U.S. confronting North Korea with its intelligence assessment that revealed that Pyongyang clandestinely continued its uranium enrichment program, North Korea announced once again that it would withdraw from the NPT. Even if the Trump administration were able to claim a major diplomatic victory by reaching a denuclearization agreement with North Korea, the risk remains that Pyongyang may well violate that agreement.
Trumps agreement to meet with Kim may bring a welcome pause to the leaders bellicose rhetoric, and it may thereby ease the concern about a military conflict on the Korean Peninsula. But the road ahead is long and perilous, with ample opportunities to trip up, fall into a trap or eliminate an opportunity for lasting peace with a single tweet.
