[President Trump’s public showmanship on North Korea] is creating a huge buzz where everyone wants to know what’s going on and what comes next...It’s a very dramatic way of conducting foreign policy and national security. But it creates a thin veneer of understanding. It’s mostly about symbolism...[Trump’s focus is] very much getting the public involved and invested in what’s going on. That’s the way you shape the narrative...[South Korea President] Moon is doing something similar. By televising the summit, televising the meetings, he’s creating an intimacy between the viewer and the object.
