Is this story self-consistent? Consider that:

(i) it's easy to make stars go nova.

(ii) when a star goes nova, its Alderson lines disappear, disconnecting parts of the network from each other, and stopping a war if the different sides are no different parts of it (the fact that the network is sparce is important here)

(iii) both Babyeaters and the Superhappies know this

(iv) nevertheless the Superhappies still plan to prosecute a war against the babyeaters
