And even assuming we did spot a meteor coming towards Earth, what would we do? Launch a nuke at it, a la Armageddon. All that would accomplish would be splitting the meteor into smaller meteors. Then the Earth would be pelted with several smaller, now radioactive, meteors.
In short, we'd be screwed.

There has been a theory that firing several nuclear weapons infront and to the side of the object over a period of time, might alter the projectiles trajectory and hopefully avoiding a collision.
