North Korean Threat & Deterrence
South Korea faces the most immediate North Korean threat of any nation, with Seoul's 25 million metropolitan residents within range of North Korean conventional artillery, rockets, and nuclear weapons.

- Artillery: North Korea has thousands of artillery pieces and rocket launchers within range of Seoul, capable of massive conventional destruction in the opening hours of any conflict
- Nuclear: KN-23, KN-24, and KN-25 short-range ballistic missiles explicitly designed for Korean peninsula use; some assessed as nuclear-capable
- Special Operations: 200,000+ DPRK SOF; tunnels under the DMZ; infiltration capability
- Cyber: North Korea has conducted major cyberattacks on South Korean banks, government systems, and defense contractors
- ROK Response: Korea Massive Punishment and Retaliation (KMPR) strategy threatens decapitation strikes on DPRK leadership in response to nuclear use
