This post from 38 North compares the North Korean (possible, budding?) peace process to the Camp David accords of 1978-79.

The Camp David agreements were also implemented in phases over time. Moreover, US troops were stationed in the Sinai as part of the UN’s Multinational Force and Observers (MFO) to ensure an effective transition from Israeli occupation to Egyptian rule there and keep the peace. In effect, this was a peace enforcement mechanism; and if the Korean War is to be brought formally to a close, then some kind of analogous mechanism may well be needed that can prevent violations of the accords involved. It might be necessary and beneficial for all the parties to the Korean conflict to have some impartial outside party, trusted by all sides—such as Sweden or India—to monitor moves toward peace. In the nuclear sphere, that could likely be the IAEA because it alone has the depth of technical capability and international standing to report credibly on steps towards complete denuclearization and verify its occurrence. But along the 38th parallel, it might be desirable for someone agreeable to both sides to perform functions analogous to those carried out by US forces in the Sinai. As noted above, we have cited the UN MFO in the Sinai or we could look to alternatives like the UN Interim Force in Lebanon (UNIFIL). Other alternatives may, of course, be possible. But presumably some such mechanism will be needed to distance the now hostile armed forces from each other and the truce lines at the 38th parallel.
