Duh, in physics there's a widely-used concept of "order of magnitude"
calculations were you simply try to get within a factor of ten of the real
value. A factor of three is pretty good when you're only aiming for a
factor of ten. Whether it's fifteen or six tons is immaterial, because
it's certainly *not* ten thousand tons.

But as I pointed out, by James calculations a 10MT groundburst nuke on the
moon will have the roughly same effect on underground structures as on the
Earth.

The moon has a factor of four energy advantage, Earth has nukes; That's
it. As you say yourself, "there's no such thing as a free lunch"; shame
that Heinlein didn't apply that maxim to his own scenarios and not just to
other people's.
