America has been trying to negotiate with North Korea since its inception with the collapse of the Japanese Empire in 1945. In all of that time, nothing much has been achieved. Things got steadily worse for the first five years or so, culminating in the outbreak of open warfare in 1950; Then things very slowly and painfully got better to the point of a ceasefire after three years of bloodshed, since when there has been ongoing effort to negotiate an actual peace treaty, which has achieved almost exactly nothing, other than to send some of the American's best negotiators and diplomats insane.
Dealing with North Korea is fundamentally impossible; They will not and cannot be pinned down to any kind of commitment, even on trivia such as the design of the conference table at which negotiations might take place.
The idea that a buffoon like Trump could march in and resolve one of the most intractable and long-running diplomatic problems in the world was always completely laughable.
That anybody ever thought that it might happen is a horrifying indictment of the post-factual world in which we live. Flat Earth theorists have better support for their position than people who thought Trump could solve the Korean issue - or even could obtain any significant concessions from Kim.
