NEW IDEA(S)!
Why aren´t there more ways to destroy a planet?
First, to blast it into stone age(with some planetary bombardment), like Ron and Blair say it will be.
Second, to create a very large hole(with one auto-piloted, slow-going misile) from it´s surface to it´s core and seriously diminsh it´s production capabilitis.
Third, to destroy them into asteroids(this woud be the most expensive method, done by Death star-type of super-wepon on wich´s construction shoud all the other races be warned about).
