while they may be on the same page about the significance of the event, itself, there are still huge differences between what north korea wants and what the united states wants when it comes to denuclearization. north korea has been calling for sanctions relief right away. the united states wants north korea to give up its nuclear weapons or at least agree on a definition of denuclearization and despite all of those feel-good moments at the demilitarized zone, those differences remain, ana, which doesn't bode well for the future of working-level talks. >> what does the u.s. now get out of this? >> well, what the united states gets is a restart of diplomacy after the north koreans basically shut everything down, when president trump walked out of talks in february in hanoi, vietnam. a source told me at that time that north koreans were actually told not to engage with the united states. obviously, the orders have changed. kim jong-un and trump are now back on a friendly footing and they have agreed within the next couple of weeks to form teams that will resume working-level talks.
