Give Trump and Kim credit for walking us back from war

There is a phrase in Korean: "Begun is half-done." It means when tackling a difficult task, half of the battle is getting started.

Despite the many warts in President Donald Trump's unconventional diplomacy toward North Korea, we have to give him credit. Only five months ago, based on my conversations with this administration, I thought we were headed down an inexorable path toward a devastating war.

A military attack would not have ended North Korea's nuclear weapons program. Instead, it would have resulted in a war — with hundreds of thousands of deaths in Japan and South Korea, including thousands of Americans — that the U.S. would have won but with horrible costs.

Thanks to the creative Olympics diplomacy from President Moon Jae-in of South Korea, which teased the North Koreans out of their self-imposed isolation, and Trump's impulsive decision to meet with the North Korean leader, Kim Jong Un, the world witnessed a historic meeting on Tuesday between two countries that have been sworn enemies for almost seven decades.

Kim arrived early for the summit meeting as a sign of respect for his counterpart, who is more than twice his age. Trump played the role of the elder host, gently guiding Kim to the meeting room, showing him his limousine and reporting to the news media about the good-natured flavor of the meetings. Those personal touches in summit diplomacy can create unique opportunities for trust-building that a normal diplomatic démarche cannot.

To be sure, the joint statement that Trump and Kim released after their meeting left a lot to be desired. Kim did not commit to verifiable and irreversible dismantlement of North Korea's nuclear programs. Trump gave props to a dictator who, according to the United Nations, belongs in a docket before the International Criminal Court for crimes against humanity. Trump surprised his South Korean ally by announcing that he would cancel joint U.S.-South Korea military exercises that help to keep the peace on the Korean Peninsula. The photo opportunity of a face-to-face meeting with the leader of the free world is the ultimate legitimizer for this nuclear rogue state.

Yet, in the case of North Korea, there are never good policy options — there are only choices between the bad and the worse.

Trump now needs to get North Korea to provide a full declaration of its nuclear weapons that will be verified by international inspectors. After verification, Kim must begin a process of dismantling and removing his weapons at a point in the future. The international community, despite its ambivalence to Trump, will have to support the American president in holding the North to these obligations.

Trump's concessions will raise some eyebrows. What type of security assurances is the U.S. agreeing to? Will Trump eventually remove American forces from the Korean Peninsula in return for denuclearization? And why did the U.S. not insist on any human rights concessions as part of the deal?

But despite its many flaws, the Singapore summit represents the start of a diplomatic process that takes us away from the brink of war.

North Korea will not be testing any more missiles or nuclear bombs while the diplomacy continues, and the talks led by Pompeo will hopefully make progress toward stopping the world's worst runaway nuclear program.

For Pyongyang, it may not have mattered who won the 2016 U.S. presidential election; North Korea would still have conducted many ballistic missile tests and a hydrogen bomb test. And a more conventional president might not have broken the mold by addressing the problem with a direct meeting with the Korean dictator. Trump's unconventional approach leaves a lot to be desired in the foreign policy of the U.S., but there was no other path to this less-than-satisfying but digestible outcome.
