Tilting the Balance

“I am not certain the details are known, especially since the accident killed some of their scientists,” Okamoto said. “But those who still live are pressing ahead. We shall not make the mistakes they did. The Americans have succeeded in running a pile without immediately joining their ancestors, and they are sharing some of their methods with us.”

“Oh.” Teerts wished he had some ginger to chase away the lump of ice that formed in his belly. When the Race came to Tosev 3, the patchwork of tiny empires that dotted the planet’s surface had been a matter for jokes. It wasn’t funny any more. Back on Home, only one line of experiment at a time would have been pursued. Here, all the competing little empires worked separately. Disunion usually was weakness, but could also prove strength, as now.

Yoshio Nishina came into the room. His alarmingly mobile lips-or so they seemed to Teerts-pulled back so that he showed what was for a Big Ugly a lot of teeth. Teerts had learned that meant he was happy. He spoke with the other scientist and with Major Okamoto. Teerts did his best to follow, but found himself left behind.

Okamoto eventually noticed he’d got lost. “We have had a new success,” the interpreter said. “We have bombarded uranium with neutrons and produced the element plutonium. Production is still very slow, but plutonium will be easier to separate from uranium-238 than uranium-235 is.”

“Hai,” Nishina echoed emphatically. “We prepared uranium hexafluoride gas to use to separate the two isotopes of uranium from each other, but it is so corrosive that we are having an impossible time working with it. But separating plutonium from uranium is a straightforward chemical process.”

Major Okamoto had to translate some of that, too. He and Teerts used a mixture of terms from Nipponese and the language of the Race to talk about matters nuclear. Teerts took for granted a whole range of facts the Big Uglies were just uncovering, but though he knew that things could be done, he often had no idea as to how. There they were ahead of him.

Nishina added, “Once we accumulate enough plutonium, we shall surely be able to assemble a bomb in short order. Then we will meet your people on even terms.”

Teerts bowed, which he found a useful way of responding without saying anything. The Nipponese didn’t seem to have any idea how destructive nuclear weapons really were. Maybe it was because they’d never had any dropped on them. As he had a dozen times before, Teerts tried to get across to them that nuclear combat wasn’t anything to anticipate with relish. They wouldn’t listen, any more than they had those other dozen times. They thought he was just trying to slow down their research (which he was, and which, he knew, compromised his position). Okamoto said, “My country was backward until less than a hundred years ago. We saw then that we had to learn the ways of the Tosevite empires that knew more than we did, or else become their slaves.”

Less than two hundred of our years, Teerts thought. Two hundred of his years before, the Race had been just about where it was now, leisurely contemplating the conquest of Tosev 3. Best wait till all was perfectly ready. What difference could a few years make, one way or the other?

They’d found out.

Okamoto went on, “Less than fifty years ago, our soldiers and sailors beat the Russians, one of the empires that had been far ahead of us. Less than two years ago, our airplanes and ships smashed those of the United States, which had been probably the strongest empire on Tosev 3. By then we were better than they. Do you see where I am leading with this?”

“No, superior sir,” Teerts said, though he feared he did.

Major Okamoto drove the point home with what Teerts had come to think of as customary Tosevite brutality: “We do not let anyone keep a lead on us in technology. We will catch up with you, too, and teach you to learn better than to attack us without warning.”

Nishina and the other scientist nodded emphatically at that. In the abstract, Teerts didn’t suppose he could blame them. Had other starfarers attacked Home, he would have done everything he could to defend it. But war with nuclear weapons was anything but abstract-and if the Nipponese did build and use one, the Race would surely respond in kind, most likely on the biggest city Nippon had. Right on top of my head in other words.

“This is not your concern,” Okamoto said when he worried about it out loud. “We will punish them for the wounds they have inflicted on us. Past that, all I need say is that dying for the Emperor is an honor.”

He meant the Nipponese emperor, whose line was said to run back more than two thousand years and to be astonishingly ancient on account of that. Teerts was tempted to bitter laughter. Dying for the Emperor was an honor, too, but he didn’t want to do it any time soon, especially not at the hands of the Race.
