With the North Korean crisis likely to become much more dangerous than the American public appreciates, I came here to a hillside on the Demilitarized Zone to peer into a tunnel six feet wide and six feet high, 220 feet below the surface, leading north.
This is one of four North Korean infiltration tunnels discovered over the years. Each is capable of transporting 10,000 soldiers per hour behind South Korean defensive lines, and the biggest can accommodate jeeps and artillery. Based on defector interviews, the spooks believe that there are at least 15 more tunnels that haven't been found yet, and that some reach nearly to Seoul.
and the kicker:
Mr. Cho remembers attending a briefing after the gulf war, in which the North Korean army brass explained why Iraq had lost. "They said Iraq lost because it had been too defensive. `You've got to take the offensive,' they said. `Iraq didn't use all its weapons [presumably biological and chemical weapons]. If we're in a war, we'll use everything. And if there's a war, we should attack first, to take the initiative.' "
