How would you know which tunnels to nuke?

Even if the Pentagon were to develop nuclear "bunker-busters" --
relatively small bombs that penetrate the surface before exploding --
the United States would be hard-pressed to use them successfully
without knowing which of the thousands of bunkers scattered throughout
the country were the correct targets.

More to the point, how do you know_where_the bunker is. A few years ago,
AvWeek had a brief note that Swedish and German companies sold hard-rock
boring equipment that could cut a 20 foot shaft at the rate of 200 feet a
day. It doesn't take many months before for the circle of uncertainty
starting from where the bore hole starts gets beyond the lethal distance of
_any_ bunker buster, nuclear or not.

The cratering radius of a 300KT (B-61) nuclear explosion in rock is about
900 feet. If the bunker is more than 10X that distance (45 days drilling), a
maximum yeild explosion is unlikely to collapse the bunker.

Without very good HUMINT indeed, you aren't going to know the location of
the target with enough precision to kill it.
