The Shadow of Saganami (Honorverse: Saganami Island, #1)

by David Weber

Any time you arrest or kill someone who's perceived as striking out against genuine injustice, you simply create another martyr, which only provides recruits to the other side. It doesn't necessarily mean the terrorists are right; it simply means you're generating a supply of people who think the terrorists are right. So to cut off their support at its base, you must make it evident you're prepared to address the issues which spawned the resistance movement in the first place. Do it from a position of strength, by all means, and don't allow yourselves to be driven into making huge, unjustified concessions. But those issues must be addressed, and some sort of consensus about them must be reached, if you're to have any hope of finally and completely eliminating the threat."
