Writing on Facebook, Han said: “I hope the image of a Seoul reduced to ashes in the game remains in the realm of fiction.”

He dismissed concerns that the game could stoke hostility towards North Korea, saying its 1950 invasion of the South was historical fact and its military threat remained real.

Han criticised the government’s security policy, pointing to North Korea’s provision for pre-emptive nuclear strikes, plans to transfer wartime operational control and scaled-back joint South Korean-US military exercises.

He added that “peace cannot be preserved through vague hope that relies on the goodwill of the other side”.
