Just War Theory relates to Slaughterhouse-Five because a major plot event is the bombing of Dresden, a small picturesque town with no military defense or stronghold. Even though the town was purely civilian, the U.S. bombed the town, essentially leveling it and killing countless of harmless civilians. This contrasts with everything the Just Theory states, as there was was no justification to attack the town, townspeople were killed, reckless and irrational use of force, and no good resulted from it.
In the story, Chicago is hydrogen bombed by China, which is another display of overuse of force as well as lack of discrimination regarding non-combatants.
