The Long War

the conclusion that it was all to do with identity. Look at history. The founding fathers of the United States for the most part were Englishmen, right up until the moment when they realized that they needn’t be. The folk of Hell-Knows-Where by default still thought of themselves as American. But they were starting to feel closer to their neighbours on this world, a handful of communities in stepwise copies of Europe and Africa and even China with which they communicated by shortwave radio, than to the Datum folks back home. Joshua found it interesting to watch that sense of identity shifting.
    And meanwhile the relationship with Datum America itself was becoming increasingly uncomfortable. The wrangling had been going on for years. Legally speaking, a few years back President Cowley’s administration had worked out – Cowley having previously argued successfully to have all the colonists’ rights and benefits removed – that in practice it was losing out on significant tax revenues, from the trade that was blossoming both between the various Long Earth communities, and between the remote worlds on the one hand and the Low Earths and Datum on the other. And so Cowley had declared that, if you were under the ‘Aegis’ of the United States – that is, if you lived in the footprint of the nation, projected across the stepwise worlds out to infinity, East and West – you were de facto a United States citizen, living under United States laws, and liable to pay United States taxes.
    And there was the rub. Taxes? Taxes on what? Taxes to be paid how? A lot of local trade was conducted by barter, or using local scrip, or even with intangibles: a service for a service. It was only when you traded with the Low Earths that dollars and cents came into play. It was a burden on many tax-payers, in fact, to assemble enough currency to satisfy said tax demands.
    Even if you did pay, the taxes bought you what? The colonists were rich in food, fresh water and unspoiled air, and land: lots and lots of land. As for advanced products, even ten years ago you had had to run home to Uncle Sam for anything high-tech or complicated, from dentistry to veterinarian services, and you needed US dollars to purchase such things. But now, why, there was a spanking new clinic in Hell-Knows-Where itself, and a veterinarian downriver in Twisted Peak, and he had a fast horse and a partner and an apprentice. If you needed a city, well, Valhalla was an authentic campus city growing up in the High Meggers, with everything cultural and all the tech you could want.
    The colonists found it increasingly hard to understand what they needed the Datum government for – and, therefore, what they were buying with their taxes, principally sliced off the profits on the shipments of raw materials the twain caravans hauled endlessly back to the Datum. Even in this neat and civilized town, far from the think-tanks of Valhalla inhabited by the likes of Helen’s father Jack, there were some who called for cutting ties with the old US altogether.
    And meanwhile, in turn, after years of relative appeasement, in recent dealings with the Datum Joshua had detected an increasing unpleasantness about the federal government’s regard for its new young colonies. There were even mutterings back in Datum USA that the colonists were in some way parasitical, even though all their residual holdings back home had long since been liquidated. All this was no doubt linked to Cowley’s push for re-election this year; having tacked to the centre during his first run for the White House – a necessity in the aftermath of the Madison incident, when much of the population had been saved from a nuclear attack by stepping away from ground zero – some commentators suggested he was now veering back to his original support base, the virulently anti-stepper Humanity First movement. The United States had long been used to being suspicious of every other country on the planet, and was now becoming suspicious of itself.
    Joshua, looking at the sunlit sky through his window, sighed. How far could this go? It was well known that Cowley was putting together some kind of twain-based military arm to go out into the Long Earth. Seeping through the outernet there had been darker rumours, or maybe disinformation, of sterner actions to come.
    Could there even be war? Most wars of the past had been over land and wealth, one way or another. Given the literally endless riches of the Long Earth,
