“He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither…” — Declaration of Independence


“Mister Gorbachev, tear down this wall.” — Ronald Reagan, June 12, 1987


The following was written in February 2017, in the context of then-president Donald Trump’s Executive Order 13769, also known as the “Muslim ban.”

In my previous essays between the election and the inauguration, I discussed how we got here, and how we didn’t, as well as what’s distinctively worrying about the new style of politics. In the first week of the new administration, it’s worth noting that we saw an outpouring of an identity-based politics of protest against rising illiberalism and misogyny, an extraordinary level of public untruth repeated by a spokesman who showed signs of not believing what he was saying but being forced into it, and the continued surrender of Republican elites to the new order.

I’m going to return to those themes in future posts; but given that the new administration is now in power, and it’s time to interrupt analyses of how and why, with discussions of what it is doing.

The populist authoritarianism that is rising across developed countries, the United States very much included, is characterized by a zeal to harden borders. Trade and migration are, between them, the great villains of the modern populist imagination, surpassing even domestic dissent. And, unsurprisingly, the first week of Donald Trump’s presidency included sharp blows against both the gradually liberalizing international trade order that the United States has led since World War II, and the freedom of human beings to move from place to place in the world. The chaos of the administration’s cruel and poorly-planned action against border-crossing by those born in seven Muslim countries is emerging as the defining act of these early days.

For an earlier generation of conservatives, a militarized wall on an international boundary symbolized the evils of Communism and Soviet domination in eastern Europe.

Walls work in both directions—they keep people in, as well as out. The administration’s decision to suspend reentry for lawful residents who were abroad at the time of the order effectively told non-citizens in the United States — permanent residents, long-since admitted refugees or those granted asylum, spouses and students and H1-B visa holders doing highly skilled work that the country needs — that they travel outside the United States at risk of not being allowed to return. Even the eventual decision to allow permanent residents to re-enter on a case-by-case basis was presented as an exercise of agency discretion, not a disavowal of the tactic.

The word of the United States isn’t good anymore — “permanent” resident now means something much less than that, and refugee status once granted might be revoked with no notice. Henceforth, peaceful, law-abiding residents will be much more afraid to leave the country. The barriers to letting people in thus act as a kind of cage to keep people in. Caged people aren’t free.

I wrote in Rationalism, Pluralism, and Freedom that:

“The core of liberal ideas includes religious toleration and freedom […], the rule of law, and especially the control by law of the executive’s security apparatus through habeas corpus, procedural rights, and prohibitions on torture and extrajudicial executions, imprisonment, or dispossession[…], and the desirability of commerce and international trade.” (p. 87)

Not only did all three elements of this core come under assault in Trump’s first week in office — they came under assault specifically in association with his war on migrants: religious discrimination in migration, extrajudicial detention being carried in airports, and the idea of a 20 percent tariff wall on goods to pay for the physical border wall.

Notwithstanding some current talking points, the new immigration restrictions are religiously discriminatory in both intent and effect. Rudy Giuliani openly acknowledged that this was the policy crafted in order to get as close as possible to the ban on Muslim immigration Trump called for on the campaign trail, while maybe being able to legally get away with it. And the combination of the identification of seven overwhelmingly Muslim countries as the source of the supposed security threat (though zero nationals of those countries—zero—have killed anyone in an act of terrorism on U.S. soil) with special exemptions for Christians from those countries turns the new restrictions into exactly what Giuliani’s account leads us to expect: a religiously-exclusionary act with a veneer of a security excuse.

As Dylan Matthews argues, the liberal political theorist Judith Shklar’s essay “The Liberalism of Fear” helps us to see the centrality of resisting cruelty and lawless state violence to the liberal vision of the free society. (My first book aimed to apply Shklar’s insights to the political treatment of ethnic and cultural minorities; its title was a direct reference to the essay.) Until the end-of-week Muslim ban and abandonment of refugees, I would have said that the great horror of Trump’s first week was the mooted possibility of reopening black site prisons and his enthusiasm about torture—an enthusiasm he says he’ll reluctantly hold in check in deference to the views of some of his top appointees, though it’s hard to imagine his “deference” to these subordinates lasting forever.

But the developing war on immigrants puts us squarely into liberalism-of-fear terrain now. Coercive border control is an especially central location for those fearful rule-of-law concerns. It routinely involves indefinite detention without legal counsel or trial. While intelligence agencies all too often exercise state violence without legal oversight, for those charged with border control it is a constant. This weekend, legal residents of the United States were prevented from boarding their planes home, or on arrival in the U.S., were physically detained without counsel or legal process.

While at this writing the situation remains unclear, there are reports that even after judicial rulings against aspects of the new policy, border patrol agents were refusing to recognize court orders. Trump advisor Stephen Miller seemed to adopt an especially strong attitude of disregard for judicial oversight, maintaining that a court order neither “impedes or prevents the implementation of the president’s executive order which remains in full, complete and total effect.”

And even before the Muslim ban was announced, the new executive orders on border control significantly expanded the arbitrary authority of immigration control officers to decide whom to deport, and insisted on a huge increase in those undocumented migrants—including asylum-seekers—who would be kept in indefinite detention. (Dara Lind at Vox, author of that latter piece, has been providing especially important and valuable coverage of these issues.)

For four months, all refugee admissions will be suspended, from everywhere in the world, abandoning many to the repression and war from which they are fleeing. The refugee suspension has perhaps gotten the least attention in the U.S., as it lacks some easily-understood and high-profile features of the Muslim ban: both the religious discrimination and the exclusion from reentry of people who have already lived here.

But it is no less cruel. People whose claim for refuge has already been judged valid, people who have already been “vetted” as posing no security risk, people fleeing war zones and repression from anywhere in the world, now find themselves locked out. This keeps refugee camps that much fuller, leaving that much less space for new people also fleeing. It further encourages very dangerous alternatives, such as families entrusting themselves to smugglers or to risky self-help in boats or on foot. Locking refugees out is a violation of international law; more to the point, it is monstrous, and renders the U.S. a kind of jailer for people at risk, keeping them locked in where they are now.

In treating peaceful civilian migration the way states treat invading armies, coercive border control always involves a deeply suspect kind of lawless violence. These aren’t permanent features of political life. The system of passports and visas as required for international movement and migration is surprisingly recent. Open, document-less borders within Europe were closed as an emergency measure during World War I; the generalized world system of passports wasn’t imposed until 1920. The passport as a document was much older, but mainly offered protection to local subjects traveling abroad. It could confirm one’s identity, but was not normally a requirement for crossing frontiers.

The liberal understanding of free societies and politics grew in part out of life in commercial medieval European cities—cities whose walls were to keep out armies, not civilians (or goods, as the cities were entirely dependent on trade). In the famous legal principle that governed those cities, “city air makes you free;” one who lived in such a city for a year and a day gained the freedom of city life against the oppression of the feudal countryside. The cities were proud of this, and grew by it.

After enjoying open borders for half of its history, the U.S. has had a deeply unhappy series of experiences with border control. The first federal regulation on entry was a racist restriction on Chinese migrants, the second a similar de facto regulation of those from Japan. There have been recurring restrictions on the grounds of political beliefs.

During the middle decades of the 20th century when U.S. immigration was most severely limited, Franklin Roosevelt turned away Jewish refugees fleeing Hitler on the grounds that they might include German spies — an approach that is all but indistinguishable from the contemporary conflation of those fleeing war and persecution in majority-Muslim countries with radical Islamist terrorists. (Many of those turned away then died in the Holocaust; and many of those turned away now may die in their home countries’ civil wars or despotic regimes.)

And the long effort to prevent migration across the southern border has seen a constant expansion of intrusive police power, and an extension of border control authority deep into the territory of the United States, putting a majority of the American population in regions where border agents wield extra-Constitutional powers.

Many people have gradually come to acknowledge the failure of a drug war focused on militarized border interdiction, and the cost in subjecting Americans to a domestic militarized police force trying to suppress supply of drugs for which there is demand. Such policies finally turned much of northern Mexico into a near-war-zone, with wealthy and violent drug cartels enjoying the profits of U.S. prohibition. (This is, of course, not unrelated to many Mexicans’ attempt to flee into the U.S.)

We should expect no different from a war on immigration. A wall can’t stop the operation of supply and demand, whether for labor or for safe refuge; it can only enrich the illegal smugglers who learn how to defeat it. And hunting migrants peacefully living inside the U.S. requires constant invasion of everyone’s privacy and liberty, not just that of the migrants themselves.

Every relationship from the workplace to the classroom to marriage is subject to regulation and prohibition: you may not employ, or teach, or marry whom you wish. But they’re also all subject to policing: who are your students? Have you checked your employees’ papers? Are you really married to your spouse?

Far too many people seem to believe that the system of walls, cages, and lawless state action can be safely aimed only outward — against strangers, against those with no claim on the United States — and that the shift toward populist authoritarian nationalism at the border can be cordoned off from domestic liberty. Even if it were right (which it’s absolutely not), to disregard the cost to those strangers’ liberty — to lock them in their countries of origin, however tyrannical, violent, or impoverished they may be — that’s not how it works. A society can’t close itself off and remain free.
