Two experts on North Korea, Victor Cha and David Chang, writing for Foreign Policy magazine, estimated that the DPRK forces could fire up to 500,000 rounds towards the city in the first hour of a conflict. That seems a very high estimate, but even if you divide it by five the results would still be devastating. The South Korean government would find itself fighting a major war whilst simultaneously trying to manage the chaos of millions of people fleeing south even as it tried to reinforce the border with troops stationed below the capital.
