- [...] Mr. Kim, 47, is one of a small but dedicated band of South Koreans who
have been hunting for North Korean "invasion tunnels" for years, some
for decades. Only four tunnels have ever been detected, all between 1974 and
1990 and all near the border. Not one has been found since, despite thousands
of drilling operations conducted not only by the South Korean military but also
freelance prospectors like Mr. Kim.
Although
broadly dismissed as cranks, the private tunnel hunters tap into the source of
one of South Koreans' greatest fears about North Korea:
its penchant for taking its war preparations underground, a reaction to the
leveling of its military installations by United States air power during the
1950-53 Korean War. [...]
