Welcome to the April A to Z Blogging Challenge! Every year, bloggers from around the world commit to posting every day in April (except Sundays), working through the alphabet one letter at a time. This year, I’m visiting twenty-six fictional alternate Earths — worlds that diverged from our own at some crucial moment and became something wonderfully, unsettlingly different. Think of it like the TV show Sliders, which followed a group of travelers “sliding” between parallel dimensions, never quite knowing what version of Earth they’d land on next. Each day, we visit a new one. Today: X.
The World That Chose the Door Over the Window
There is a phrase that appears, in some variation, in the official national mottos, school curricula, and government slogans of nearly every nation on Xenophobic Earth. Translated from dozens of languages, it says roughly the same thing in all of them: We are enough.
It is printed on textbooks. It is carved above the entrances of government buildings. In the United States, it was added to the Pledge of Allegiance in 1931, tucked in just after indivisible, as though it had always been there. Children grow up saying it every morning without thinking about it, the way children in any world grow up saying things without thinking about them, absorbing the shape of an idea long before they have the vocabulary to interrogate it.
We are enough.
It is meant to be reassuring. In many ways, it is. In every way that matters, it is also a lie — not a malicious one, exactly, but the particular kind of lie that a civilization tells itself when it has made a decision it can no longer afford to examine.
Welcome to Xenophobic Earth, where the world closed its doors a century ago and has been trying, ever since, to convince itself that there was nothing worth keeping out there anyway.
The Divergence: What the Great War Left Behind
In our world, the First World War ended in 1918 with a settlement that was less a peace than a deferred explosion. The humiliation of Germany, the dissolution of empires, the redrawing of maps with colonial indifference to the people actually living inside them — all of it accumulated into the conditions that made a second, larger war not just possible but nearly inevitable. The world, in our history, learned the wrong lessons from its first catastrophe and walked directly into its second.
Xenophobic Earth learned different wrong lessons.
The divergence is not a single event. It is a mood, and moods are harder to pin down than assassinations or treaties. But if you had to locate it, you would point to the early 1920s — the years immediately following the armistice — when the governments and populations of the major world powers were in the particular psychological state that follows a trauma too large to process. Exhausted, grieving, economically gutted, and desperate for an explanation that didn’t require them to look at themselves too hard.
In our world, that desperation eventually pointed outward — toward old enemies, new scapegoats, the seductive logic of someone to blame. In Xenophobic Earth, it pointed inward. The conclusion drawn, not by any single leader but by a kind of collective, exhausted consensus across multiple nations almost simultaneously, was that the world had been made dangerous by contact itself. That the war had happened because nations had been too entangled with one another — through alliances, through imperialism, through the complicated web of obligations and rivalries that interconnection always produces. The solution, then, was disentanglement.
It began with the United States, which had the geographic luxury to make isolation feel plausible. The Immigration Act that passed in this world in 1924 went significantly further than its counterpart in ours — not just restricting immigration by national origin quotas but legislating toward its eventual elimination entirely. By 1931, legal immigration to the United States had effectively ceased. By 1935, the border infrastructure to enforce that cessation was among the most extensive engineering projects the country had undertaken since the transcontinental railroad.
Europe moved differently but arrived at the same destination. The League of Nations collapsed faster here than in our timeline — not because the United States refused to join, but because the member nations discovered, one by one, that they didn’t actually want to be bound by its obligations. What replaced it was not an alternative institution but a vacuum, which filled gradually with bilateral non-contact agreements: treaties whose primary clause was, in effect, a mutual promise to leave each other alone.
By 1940 — the year our world was descending into its second global catastrophe — Xenophobic Earth was quiet. Borders were closed. Travel was restricted to the near-impossible. International trade had contracted to a trickle of essential resources, conducted through heavily intermediated channels specifically designed to minimize human contact. The world was not at peace, exactly. But it was still.
The Architecture of Separation
Understanding how Xenophobic Earth actually functions requires setting aside the instinct to see it as simply our world with the borders turned up to maximum. The isolationism here is not just policy. After a century, it is infrastructure — physical, legal, psychological, and institutional — and it has reshaped every system it has touched.
Travel between nations is not merely discouraged; it is, in most countries, illegal without government authorization that is vanishingly rare to obtain. Passports exist but function as historical curiosities for most citizens — documents that grandparents might have possessed, kept in drawers alongside other artifacts of a more porous era. The generation alive today in most of Xenophobic Earth’s nations has never met a foreign national in person. Most have never heard a foreign language spoken aloud by a native speaker. Many have never tasted food from another country’s culinary tradition, because the ingredients required to make it are no longer imported.
Media is entirely domestic by legal mandate in most nations, and by infrastructure in the rest. There is no global internet — the connected communication networks that emerged in the mid-twentieth century were deliberately built as national systems, incompatible with one another by design rather than by accident. The United States has its own network. So does France. So does Japan. They do not speak to one another. There are no international phone calls available to ordinary citizens. Letters to foreign addresses are accepted by post offices with forms that must be filed in triplicate, approved by two separate government agencies, and are — according to anyone who has tried — never actually delivered.
Languages have drifted in the way that languages drift when they stop being in contact with each other. English in the United States of Xenophobic Earth is recognizable but strange — it shed its twentieth century loanwords and never acquired new ones, it evolved its slang in isolation, and it has not been contaminated by, nor has it contaminated, any of the dozens of other languages that in our world have left fingerprints on American speech. French in France sounds, to linguists who have managed to compare recordings, as though it took a century-long detour. The languages of smaller nations have in some cases changed so dramatically that neighboring countries’ populations, who share land borders maintained by wire and concrete, can no longer communicate with each other even if they were allowed to try.
Technology developed, but unevenly and in strange directions. The absence of cross-cultural scientific exchange — no international conferences, no collaborative research institutions, no brain drain and brain gain between nations — meant that each country’s scientific progress depended entirely on its own domestic talent pool and its own domestic priorities. The United States made significant advances in agricultural technology, in domestic communications infrastructure, in certain fields of medicine. It did not develop nuclear weapons — the Manhattan Project in our world was, among other things, a profoundly international enterprise, and the specific combination of expertise that made it possible did not exist inside any one nation’s borders. Neither did any other nation develop them. This is, perhaps, the one outcome of Xenophobic Earth’s arrangement that comes closest to an argument in its favor. The world has no nuclear arsenal. It also has no antibiotics developed after 1952, no satellites, no organ transplantation programs, and a life expectancy roughly twelve years below our own.
The Countries That Tried Otherwise
Not every nation embraced the isolationist order willingly, and the history of Xenophobic Earth includes a handful of episodes where resistance was tried — and what happened to it.
The most significant of these was the brief experiment of what historians on Xenophobic Earth call the Open Compact — a loose alliance formed in the late 1930s among several smaller nations, primarily in Scandinavia and the Low Countries, that refused to fully implement border closure and continued to maintain cultural and economic exchange with one another. At its peak, the Open Compact represented perhaps forty million people living under a different set of assumptions: that exchange was not the cause of war but one of the available remedies for it, that a world of strangers would always be more dangerous than a world of neighbors, that the medicine being administered for the disease of the First World War was going to kill the patient.
They were not wrong. They were also not, ultimately, successful.
The pressures on the Open Compact were relentless and took several forms. Economically, their continued openness made them dependent on trading relationships that their larger neighbors were systematically dismantling. Politically, they were treated by the closed nations as a destabilizing presence — living evidence that the isolationist consensus was a choice rather than an inevitability, which was the one thing the closed nations could not afford to acknowledge. By the mid-1950s, a combination of economic strangulation, internal political fracturing encouraged by external pressure, and the simple exhaustion of sustaining a different vision against the current of the entire world had reduced the Open Compact to an arrangement that existed on paper but not in practice.
The last member nation formally closed its borders in 1961. The records of what the Open Compact had argued and attempted were not destroyed — censorship on Xenophobic Earth is less dramatically totalitarian than that — but they became, over subsequent decades, the kind of historical footnote that children learn one sentence about and adults don’t think to ask further questions about. The countries involved are, today, indistinguishable from their neighbors in terms of their border policies, their cultural insularity, and their genuine puzzlement when younger citizens, encountering that one sentence, ask why it didn’t work.
The Stagnation Beneath the Peace
The thing that is hardest to convey about Xenophobic Earth, if you are trying to explain it to someone from outside, is that it does not feel, from the inside, like a dystopia. The word dystopia implies suffering that is visible and acknowledged, a population that knows something is wrong and is being prevented from fixing it. Xenophobic Earth does not look like that. It looks like a world that is, by most surface measures, doing fine.
Crime exists, as it does everywhere. There are political disagreements, economic anxieties, social tensions of the kind that human societies always generate. People fall in love, raise children, watch whatever passes for entertainment, argue about sports and weather and the particular local grievances that every community produces. The streets are not in ruins. The governments, while authoritarian in their border enforcement, are not generally totalitarian in their domestic arrangements — the United States of Xenophobic Earth is a recognizable democracy in its internal politics, with elections and a free press and the full ordinary machinery of a functioning republic, all operating contentedly within walls it no longer thinks to question.
What is wrong is harder to see because it accumulates slowly and looks, in any given decade, like simply the way things are.
The intellectual life of Xenophobic Earth is narrower than it should be, in a way that is almost impossible to perceive from inside it. The questions that don’t get asked because the people who would have asked them were never born here, or died here and were never heard, or existed but lacked the collaborators whose existence would have sharpened and challenged and redirected their thinking. The art that wasn’t made. The medicine that wasn’t developed. The philosophical traditions that hardened into orthodoxy because there was no foreign tradition to argue with, no outside perspective to force a reconsideration. The stories that stopped being told because the experiences that generated them stopped being shared across borders.
There are historians on Xenophobic Earth — careful, serious people working within their national traditions — who have begun to notice the shape of the gap. It requires a particular kind of intellectual courage to look at your own civilization and ask not what it has, but what it should have by now and doesn’t. A few of them have published papers that circulate quietly in academic circles, papers that use phrases like arrested development and compounding insularity and the asymptotic ceiling of closed systems. They are not celebrated. They are not suppressed either. They are, which may be worse, simply not widely read.
The peace is real. The war that didn’t happen really didn’t happen, and the people who didn’t die in it are genuinely not dead. This is not nothing. On the scales of history, it may even be significant.
But the peace is also the name that Xenophobic Earth has given to its stagnation, and the stagnation has been going on for a hundred years, and somewhere in the arithmetic of everything that has not been discovered, not been created, not been shared, not been challenged and changed and made better by contact with something different — somewhere in that arithmetic is a number that is very hard to look at directly.
We are enough.
It is printed on textbooks. It is carved above the entrances of government buildings. In the quiet offices of the historians who have started asking the wrong questions, it appears on a sticky note above a desk, underlined twice, with a single word written next to it in careful, uncertain handwriting.
Are we?
Join me tomorrow for Y — and another world waiting just beyond the edge of what we know.
