Well no, if it's orbiting the Earth then you require a certain amount of
energy to decelerate it until it hits the Earth's atmosphere. That's a lot
of energy, and a small nuke just won't provide it.

AFAIR the L5 folx reckoned it was more like 90% of the mass, and the
mass-drivers were roughly the same size as those used on the moon. You're
changing your scenario again; if you'd originally said that an asteroid
belt society (if such a thing is possible) could defend itself against the
Earth this way then I would probably have agreed. They'd be hard to find,
hard to hit, and able to cause a lot of damage to Earth.

In the long-run, planets really are a bad place to be.
