The patriarchs of the two families had no particular opinion about there still being humans on the surface.
They even believed that the legend about alien invaders conquering Earth a millennium ago might not be true. It was more likely a geological disaster on the surface forced humans to migrate underground, and now the surface is no longer suitable for survival, with no need to go up.
Overall, their attitude was simple: the surface is too dangerous, opposing alien invaders is asking for death. Whatever you want to do, don't drag us into it, and don't bring trouble underground.
Even when resources were scarce at the time, they had no intention of returning to the surface. They planned to address the issue starting with other areas underground since the underground world was vast.
In the end, the negotiations came to nothing.
