The stocky man's eyes burned.
"Are you laughing at me?" he demanded.
"I've been three months in overdrive," Calhoun reminded him. "I haven't heard anything to laugh at in longer than that. No."
"The ... our enemy," said Walker bitterly, "consider that they have won the war! But you may be able to make them realize that they have not, and they cannot. We have been foolishly patient, but we can't risk forbearance any longer. We mean to carry through to victory even if we arrive at cutting our own throats for a victory celebration! And that is not unlikely!"
Calhoun raised his eyebrows. But he nodded. His studies had told him that a war psychology was a highly emotional one.
"Our home planet Phaedra has to be evacuated," said Walker, very grimly indeed. "There are signs of instability in our sun. Five years since, we sent our older children to Canis III to build a world for all of us to move to. Our sun could burst at any time. It is certain to flare up some time—and soon! We sent our children because the place of danger was at home. We urged them to work feverishly. We sent the young women as well as the men at the beginning, so that if our planet did crisp and melt when our sun went off there would still be children of our children to live on. When we dared—when they could feed and shelter them—we sent younger boys and girls to safety, overburdening the new colony with mouths to feed, but at the least staying ourselves where the danger was! Later we sent even the small children, as the signs of an imminent cataclysm became more threatening."
Calhoun nodded again. There were not many novas in the galaxy in any one year, even among the millions of billions of stars it held. But there had been at least one colony which had had to be shifted because of evidence of solar instability. The job in that case was not complete when the flare-up came. The evacuation of a world, though, would never be an easy task. The population had to be moved light-years of distance. Space travel takes time, even at thirty times the speed of light. Where the time of disaster—the deadline for removal—could not be known exactly, the course adopted by Phaedra was logical. Young men and women were best sent off first. They could make new homes for themselves and for others to follow them. They could work harder and longer for the purpose than any other age-group—and they would best assure the permanent survival of somebody! The new colony would have to be a place of frantic, unresting labor, of feverish round-the-clock endeavor, because the time-scale for working was necessarily unknown but was extremely unlikely to be enough. When they could be burdened further, younger boys and girls would be shipped—old enough to help but not to pioneer. They could be sent to safety in a partly-built colony. Later smaller children could be sent, needing care from their older contemporaries. Only at long last would the adults leave their world for the new. They would stay where the danger was until all younger ones were secure.
"But now," said Walker thickly, "our children have made their world and now they refuse to receive their parents and grandparents! They have a world of young people only, under no authority but their own. They say that we lied to them about the coming flare of Phaedra's sun: that we enslaved them and made them use their youth to build a new world we now demand to take over! They are willing for Phaedra's sun to burst and kill the rest of us, so they can live as they please without a care for us!"
Calhoun said nothing. It is a part of medical training to recognize that information obtained from others is never wholly accurate. Conceding the facts, he would still be getting from Walker only one interpretation of them. There is an instinct in the young to become independent of adults, and an instinct in adults to be protective past all reason. There is, in one sense, always a war between the generations on all planets, not only Phaedra and Canis III. It is a conflict between instincts which themselves are necessary—and perhaps the conflict as such is necessary for some purpose of the race.
