Shocked and embarrassed, Ross mumbled some kind of answer. One might think of war, good breeding taught, but one never talked about it. “You should,” the old man said hoarsely. “War is what this faster-than-light secrecy and identification rigmarole is all about. Right now war is impossible—between solar systems, anyhow, and that’s what counts. A planet might just barely manage to fit an invading multigeneration expedition at gigantic cost, but it never would. The fruits of victory—loot, political domination, maybe slaves—would never come back to the fitters of the expedition but to their remote descendants. A firm will take a flyer on a commercial deal like that, but no nation would accept a war on any such basis—because a conqueror is a man, and men die. With F-T-L—faster-than-light travel—they might invade Curnus or Azor or any of those other tempting dots on the master maps. Why not? Take the marginal population, hop them up with patriotic fervor and lust for booty, and ship them off to pillage and destroy. There’s at least a fifty per cent chance of coming out ahead on the investment, isn’t there? Much more attractive deal commercially speaking than our present longliners.” Ross had never seen a war. The last on Halsey’s planet had been the Peninsular Rebellion about a century and a half ago. Some half a million constitutional psychopathic inferiors had started themselves an ideal society with theocratic trimmings in a remote and unfruitful corner of the planet. Starved and frustrated by an unrealistic moral creed they finally exploded to devastate their neighboring areas and were quickly quarantined by a radioactive zone. They disintegrated internally, massacred their priesthood, and were permitted to disperse. It was regarded as a shameful episode by every dweller on the planet. It wasn’t a subject for popular filmreels; if you wanted to find out about the Peninsular Rebellion you went through many successive library doors and signed your name on lists, and were sternly questioned as to your age and scholarly qualifications and reasons for sniffing around such an unsavory mess. Ross therefore had not the slightest comprehension of Haarland’s anxiety. He told him so. “I hope you’re right,” was all the old man would say. “I hope you don’t learn worse.” * * * * * The rest was work. He had the Yard worker’s familiarity with conventional rocketry, which saved him some study of the fine-maneuvering apparatus of the F-T-L craft—but not much. For a week under Haarland’s merciless drilling he jetted the ship about its remote area of space, far from the commerce lanes, until the old man grudgingly pronounced himself satisfied.
