Terrible history shows what Trump's migrant 'camps' really are — and what comes next

As people testified before Congress on Tuesday about the brutality and violence they’d suffered at the hands of ICE, that massive paramilitary organization was shopping for giant warehouse-style facilities they can retrofit into what they euphemistically call “detention centers.”

Cable news people call them “prison camps” or “Trump prison camps,” but look in any dictionary: prisons are where people convicted of crimes are held. As Merriam-Webster notes, a prison is:

“[A]n institution for confinement of persons convicted of serious crimes.”

Jails are where people accused of crimes but still waiting for their day in court are held, as Merriam-Webster notes:

“[S]uch a place under the jurisdiction of a local government for the confinement of persons awaiting trial or those convicted of minor crimes.”

But what do you call a place where people who’ve committed no criminal offense (immigration violations are civil, not criminal, infractions)? The fine dictionary people at Merriam-Webster note the proper term is “concentration camp”:

“[A] place where large numbers of people (such as prisoners of war, political prisoners, refugees, or the members of an ethnic or religious minority) are detained or confined under armed guard.”

The British originated the term “concentration camp” to describe facilities where “rebel” or “undesirable” civilians were held in South Africa during the Second Anglo‑Boer War (1899–1902) to control and punish a rebellious population.

They were facilities where the “bad elements of society” were “concentrated” into one location so they could be easily controlled and would lose access to society and thus could not spread their messages of resistance against the British Empire.

The Germans adopted the term in 1933 when Hitler took power and created his first camp for communists, socialists, union leaders, and, by the end of the year, Hitler’s political opponents. They Germanized the phrase into “Konzentrationslager” and referred to the process of their incarceration as “protective custody.”

The first camp was built at Dachau just weeks after Hitler became Chancellor in 1933, and by the end of the year there were around 70 of them operating across the country.

When Louise and I lived in Germany in 1986-87, we visited Dachau with our three children. The crematoriums shocked our kids, but even more so because this was simply a “detention facility” and not one of Hitler’s death camps (which were all located outside Germany to ensure deniability).

The ovens at Dachau were for those who had been worked to death or killed by cholera or other disease, much like the 35+ people who’ve recently died in ICE’s concentration camps.

When American friends would visit us and we’d take them to Dachau (we lived just an hour up the road) they’d invariably be surprised when I told them that by the time of the war there were over 500 substantial camps and an additional few hundred very small ones all over the country.

“How could the people not know what was going on?” they’d ask.

The answer was simple: the people did know. These were where the “undesirables,” the “criminal troublemakers,” and the “aliens” were held, and were broadly supported by the German people. (It wasn’t until 1938, following Kristallnacht, that the Nazis began systematically arresting and imprisoning non-political Jews, first at Buchenwald, and Sachsenhausen.)

By the end of his first year, Hitler had around 50,000 people held in his roughly 70 concentration camps, facilities that were often improvised in factories, prisons, castles, and other buildings.

By comparison, today ICE is holding over 70,000 people in 225 concentration camps across America, and Trump, Homan, Miller, and Noem hope to more than double both numbers in the coming months.

In Tennessee, the Guardian reports that Miller has been coordinating with Republican leaders to create legislation that would turn every local cop, teacher, social worker, and helper in the state into an official agent of ICE and criminalize efforts by cities to refuse cooperation. It also makes it a felony crime to identify any of ICE’s masked agents or disclose conditions within the concentration camps to the public.

Germans didn’t have the benefit of warnings from a fascist history they could look back on; much of what Hitler did took them by surprise, as I’ve noted in previous articles.

In 2026 America, however, operating with the benefit of historical hindsight, entire communities are rebelling at Trump’s effort to beat Germany’s 1933-1934 prisoner numbers.

In city after city, Americans are organizing to deprive ICE of their coveted spaces, putting pressure on companies not to sell and on cities and counties not to permit any more concentration camps.

Because immigration violations are labeled “civil,” people in ICE concentration camps are stripped of many of the normal constitutional protections that apply to people in criminal incarceration. This has created a legal black hole that ICE and the Trump regime exploit, where indefinite imprisonment, abuse, and medical neglect flourish with little to no oversight or accountability.

Human rights organizations like the ACLU describe pervasive patterns of abuse in ICE detention: hazardous living conditions, chronic medical neglect, sexual assault, retaliation for grievances, and extensive use of solitary confinement.

Detainees who have committed no crime other than being in the United States without documentation report being shackled for long periods, packed into freezing, overcrowded cells under constant fluorescent light, and denied hygiene and timely care. Meanwhile, GOP-aligned private prison companies are making billions off the program.

Inspections and oversight are inconsistent: one recent investigation found that as detentions and deaths surged in 2025, formal inspections of facilities actually dropped by over a third. ICE regularly refuses to allow attorneys, family members, and even members of Congress to access their concentration camps; the issue is now being litigated through federal courts.

History shows us that once a nation builds a mass detention apparatus, it never remains limited to its original targets. Future generations of Americans — our children and grandchildren — won’t ask us whether ICE followed civil detention statutes: they’ll want to know why we allowed concentration camps to exist in America at all.

Germany’s concentration camps didn’t start as instruments of mass murder, and neither have ours; both started as facilities for people the government’s leader said were a problem. And that’s exactly what ICE is building now.

History isn’t whispering its warning: it’s shouting.
