"Does the Little Doctor work against a planet?"
Mazer's face went rigid. "Ender, the buggers never deliberately attacked a civilian poulation in either invasion. You decide whether it would be wise to adopt a strategy that would invite reprisals."
I remember that during the Shadow series there were several references to when the Formics invaded and killed millions of Chinese and began terraforming the area with their plants as well.
Does that not count as a deliberate attack on a civilian population?
Or is Mazer referring to the fact that the Formics could not tell the difference between a civilian population and expendable extentions of a queen?
Or is this just a contradiction among the books?
