The books had a few points to make, even if it cut some corners to make them.
1. Humans are bad at real long term (generations or more) planning.
2. Humans have been successful because of their ability to trust each other. This works okay on Earth, but if they live in a universe that is actively hostile towards this, it could turn us into a doomed species.
3. Conversely, an entire universe of species that go around destroying each other on a whim is also doomed for everyone.
The only resolution seems to be that maybe if groups of both species that want to peacefully coexist can find a third place to inhabit together, they may be able to find a compromise even if their original races end up wiped out completely.
