1. There needs to be compromise on the nuclear issue.

Donald Trump's decision to take a hardline approach meant to force North Korea to completely dismantle all of its nuclear weapons is what made the Hanoi Summit fail. Given North Korea's weak economy and reliance on China to even stay afloat, the possession of nuclear weapons is one of the few sources of clout that Kim Jong-un has on the wider world stage. As the past talks have shown, he does not take the possibility of discarding them lightly

Still, leading up to and following his June 2018 meeting with Trump in Singapore, Kim voiced a willingness to make some sort of compromise on denuclearization and to halt nuclear tests (although intelligence reports suggest that North Korea may have resumed activity in some weapon facilities). In response, Trump halted the war games that the US military regularly conducts with South Korean troops. In light of this interaction, how could North Korea be enticed to stop expanding its nuclear arsenal?

Of course, Kim and Trump will need to meet halfway again, but with bigger bargaining chips. A possible solution could involve the US lowering the number of its troops in Korea and easing some sanctions in exchange for North Korea reducing the size of its nuclear arsenal and allowing international inspectors (such as those from the International Atomic Energy Agency, an international organization advocating for the peaceful use of nuclear energy) to ensure its compliance with peace agreements. Neither side would have all of its demands fulfilled completely, but it would help de-escalate tensions for future negotiations.

2. American partisan politics must stay out of the negotiations in Korea.

There is a caveat that would make the possibility of compromise with North Korea difficult: many in the US Congress have sought to prevent the US military from lowering troops numbers in Korea and, more generally, have not been supportive of Trump's attempts to negotiate with North Korea. Many Republicans have traditionally opposed such talks with the Kim regime, with some such as current National Security Adviser John Bolton taking a particularly hawkish stance on US-North Korea relations.

Lately, however, many Democrats have also been blocking attempts to reach out to North Korea, due in part to their opposition to Donald Trump. Prominent Democratic senators such as Bob Menendez of New Jersey have even called out attempts by South Korea to over economic incentives to the North in order to bring them to the negotiating table. Other Democratic leaders such as House Speaker Nancy Pelosi of California have told their Korean counterparts to be wary of negotiating with the North, much to the delight to right-wing politicians in South Korea who oppose a peace deal.

Of course, there are plenty of reasons to criticize the way in which Trump has gone about the negotiations. The failure of the Hanoi Summit shows why. It is more than reasonable to question Trump's often inconsistent approach to North Korea, which seems to change at his whim at times, and his motivations; achieving a peace deal would no doubt enhance Trump's foreign policy reputation, something Trump realizes and likely craves.

That, however, is no excuse for sabotaging a good chance to reach an agreement with the North Korean regime. Regardless of Trump's motivations, ending the Korean War is the best way to lower the risk of armed conflict on the peninsula. American negotiators will need the support of members of Congress to craft an effective agreement with North Korea, and those members who wish for peace but do not wish to give Trump a foreign policy victory should remember not to allow partisanship to cloud their judgment.

3. The best thing the US can do is to make it as easy for the Koreas to form a relationship on their own as possible.

Perhaps one of the greatest tragedies of the conflict on the Korean Peninsula is the way in which a nation having just been liberated from decades of the Japanese occupation was torn apart in large part due to the power struggle between outside powers (namely the United States, China, and the Soviet Union). Even today, the rivalry between China and the US (as well as American allies like Japan) hinders some possibilities for peace and cooperation in Korea.

Seeing that these outside powers make achieving peace difficult, it is clear that it should be up to the Koreans (from both the north and south) to decide how the two states should interact with each other. It is imperative that both China and the United States truly value allowing the people of Korea to have the power of "determining the destiny of the Korean nation on their own accord" as stated in the Panmunjom Declaration signed by Moon Jae-in and Kim Jong-un in April 2018.

Ultimately, it should be up to the Korean people to work out the relationship they choose to have with their follow Koreans on the other side of the DMZ. Despite the growing differences between those in the north and in the south, they still share a common nation and are best-suited to make the deals that would be in the peninsula's best interest. The United States should respect this right but working with China and the Koreas to end the war and leaving the Koreas to engage with each other as they wish.
