Marking the 70th anniversary of the Korean War, this report explains the practice of leafleting -- focusing on why it is such a big point of contention for North Korea. Private leaflets coming from the South Korea side of the border are seen as a demoralising insult for Pyongyang. When the North Korean public is exposed to detailed or even inflated information about the Kim family, it may lead to questioning the nature of its leadership -- a de facto theocracy.

• Leaflets are only part of “leafleting,” containing medical pills, rice and more.
• Methods of delivery have become more diverse; from helium gas to hydrogen gas, and now reportedly also involving drones.
• North Korea has always negotiated for the ceasing of leafleting. At one point in the past, Pyongyang even relocated the Kim Jong Il statue to hide it from the eyes of South Korean soldiers stationed along the DMZ.
