The primary issue that is being negotiated with North Korea is its nuclear weapons and the missiles they might be mounted on for attacks on the United States and its allies, South Korea and Japan. A meaningful agreement will have to include many technical issues.
Donald Trump and Mike Pompeo are not nuclear or rocket scientists, nor can we expect most politicians to be. But the technical facts are no less difficult to learn than the economics. (Oops! They get that wrong, too. I will push forward anyway.) Pundits commenting on the negotiations and people who simply want to understand may find this list useful.
