SciFi story

I just listened to a science fiction story about a society that started a war and ended up underground. They used robots to fight the war above. The enemy did the same. The people, of course, discover that the robots have been lying to them for some time. The war stopped very soon after all the people went underground.

When a group of people go above ground to inspect the scene, they are prevented from going back and telling every one else The robots, of course, bring both sides together on the surface to start a new. No need for diplomacy or politics because no one needs those things when they are worried about growing crops and getting enough rain.

This is the worse kind of happy ending. It is a lie. All of life exists to change the environment to fit their needs. This means all resources become precious at some point. This means not every one has everything they want and need all at once and forever. This story simply shows the robots hitting the reset button on humanity's condition. Changing from one form of distribution of wealth to another is not going to change the fact that want and need will eventually dictate action and distribution.
