No one could say.

He began to think again about the discipline of natural history which had so captivated him on Arena Glacier. It used scientific methods to study the natural world’s history, and in many ways that history was just as problematic a methodological problem.as human history, being likewise nonrepeatable and resistant to experiment. And with human consciousness out of the picture, natural history was often fairly successful, even if it was based mostly on observation and hypothesis that could be tested only by further observation. It was a real science; it had discovered, there among the contingency and disorder, some valid general principles of evolution-development, adaptation, complexification, and many more specific pri’nciples as well, confirmed by the various subdis-ciplines.

What he needed were similar principles influencing human history. The little reading he did in historiography was not encouraging; it was either a sad imitation of the scientific method, or art pure and simple. About every decade a new historical explanation revised all that had come before, but clearly revisionism held pleasures that had nothing to do with the actual justice of the case being made. Sociobiology and bioethics were more promising, but they tended to explain things best when working on evolutionary time scales, and he wanted something for the past hundred years, and the next hundred. Or even the past fifty and the next five.

Night after night he woke, failed to fall back asleep, got up, sat at the screen and puzzled over these matters, too tired to think well. And as these night watches kept happening, he found himself returning more and more to shows about 2061. There were any number of video compilations on the events of that year, and some of them were not shy about naming it: World War Three! was the title of the longest series, some sixty hours’ worth of video from that year, poorly edited and sequenced.

One only had to watch the series for a while to realize that the title was not entirely sensationalist. Wars had raged all over Terra in that fateful year, and the analysts reluctant to call it the Third World War seemed to think that it simply hadn’t gone on long enough to qualify. Or that it hadn’t been the contest of two great global alliances, but was much more confused and complex: different sources would claim it was north against south, or young against old, or UN against nations, or nations against transnationals, or transnationals against flags of convenience, or armies against police, or police against citizens-so that it began to seem every kind of conflict at once. For a matter of six or eight months the world had descended into chaos. In the course of his wanderings through “political science” Sax had stumbled across a pseudo-scientific chart by a Herman Kahn, called an “Escalation Ladder,” which attempted to categorize conflicts according to their nature and severity. There were forty-four steps in Kahn’s ladder, going from the first, Ostensible Crisis, up gradually through categories like Political and Diplomatic Gestures, Solemn and Formal Declarations, and Significant Mobilization, then more steeply through steps like Show of Force, Harassing Acts of Violence, Dramatic Military Confrontations, Large Conventional War, and then off into the unexplored zones of Barely Nuclear War, Exemplary Attacks Against Property, Civilian Devastation Attack, and right on up to number forty-four, Spasm or Insensate War. It was certainly an interesting attempt at taxonomy and logical sequence, and although there were obviously elements of fetishization in the excessive detail, Sax could see that the categories had been abstracted from many wars of the past. And by the definitions of the table, 2061 had shot right up the ladder to number forty-four.

In that maelstrom, Mars had been no more than one spectacular war among fifty. Very few general programs about ‘61 devoted more than a few minutes to it, and these merely collected clips Sax had seen at the time: the frozen guards at Korolyov, the broken domes, the fall of the elevator, and then that of Phobos. Attempts at analysis of the Martian situation were shallow at best; Mars had been an exotic sideshow, with some good vid, but nothing else to distinguish it from the general morass. No. One sleepless dawn it came to him; if he wanted to understand 2061, he was going to have to piece it together himself, from the primary sources of the videotapes, from all the bouncing shots of enraged crowds torching cities, and the occasional press conferences with desperate, frustrated leaders.

Even getting these in chronological order was no easy task. And indeed this became (in his Echus style) his only interest for a few weeks, as slotting events into a chronology was the first step in piecing together what had happened-which had to precede figuring out why.

Over the weeks he began to get a sense of it. Certainly the common wisdom was correct; the emergence of the transnationals in the 2040s had set the stage, and was the ultimate cause of the war. In that decade, while Sax had been devoting every bit of his attention to terraforming Mars, a new Terran order had come into being, shaped as the thousands of multinational corporations began to coalesce into the scores of colossal transnationals. Something like planetary formation, he thought one night, planetesimals becoming planets.

It was not entirely a new order, however. The multinationals had mostly originated in the wealthy industrial nations, and so in certain senses the transnationals were expressions of these nations-extensions of their power into the rest of the world, in a way that reminded Sax of what little he knew of the imperial and colonial systems that had preceded them. Frank had said something like that: colonialism had never died, he used to declare, it just changed names and hired local cops. We’re all colonies of the transnats.

This was Frank’s cynicism, Sax decided (wishing that he had that hard bitter mind on hand to instruct him), because all colonies were not equal. It was true that transnats were so powerful that they had rendered national governments little more than toothless servants. And no transnat had shown any particular loyalty to any given government, or the UN. But they were children of the West- children who no longer cared for their parents, yet still supported them. For the record showed that the industrial nations had prospered under the transnats, while the developing nations had had no recourse but to fight each other for flag-of-convenience status. And thus in 2060 when the transnats had come under fire from desperate poor countries, it had been the Group of Seven and its military might that had come to their defense.

But the proximate cause? Night after night he sifted through vid of the 2040s and ‘50s, looking for traces of patterns. Eventually he decided that it was the longevity treatment which had pushed things over the edge. Through the 2050s the treatment had spread through the rich countries, illustrating the gross economic inequality in the world like a color stain in a microscope sample. And as the treatment spread, the situation had gotten increasingly tense, rising steadily up the steps of Kahn’s ladder of crises.

The immediate cause of the explosion of ‘61, strangely enough, appeared to be a squabble concerning the Martian space elevator. The elevator had been operated by Praxis, but after it had started operations, in February of 2061 to be precise, it had been taken over by Subarashii, in a clearly hostile takeover. Subarashii at that time was a conglomeration of most of the Japanese corporations that had not folded into Mitsubishi, and it was a rising power, very aggressive and ambitious. Upon acquisition of the elevator-a takeover approved by UNOMA-Subarashii had immediately increased the emigration quotas, causing the situation on Mars to go critical. At the same time on Earth, Subarashii’s competitors had objected to what was effectively an economic conquest of Mars, and though Praxis had confined its objections to legal action at the hapless UN, one of Subarashii’s flags of convenience, Malaysia, had been attacked by Singapore, which was a base for Shellalco. By April of 2061 much of south Asia was at war. Most of the fights were long-standing conflicts, such as Cambodia versus Vietnam, or Pakistan versus India; but some were attacks on Subarashii flags, as in Burma and Bangladesh. Events in the region had shot up the escalation ladder with deadly speed as old enmities joined the new transnat conflicts, and by June wars had spread all over Terra, and then to Mars. By October fifty million people had died, and another fifty million were to die in the aftermath, as many basic services had been interrupted or destroyed, and a newly released malaria v ctor remained without an effective prevention or cure.
