Norman Morrison: Self-immolation as a political act.

I happened across Norman Morrison in a review of the new Taubman biography of Robert McNamara. I had also been reading comments on social media about Vietnam and the idea that self-immolation was a completely foreign concept to the western mind, particularly the Christian one. As one who attended Quaker school and was intimately acquainted and supportive of Quaker pacifism during the Vietnam War, it was obvious there was something here worth investigating; after all, isn't one of the highest military and Christian values to give your life to save the greater number? Wasn't that precisely a rationale for McNamara's support for the firebombing of Japan, an action he knew was a war crime?

During World War II he became a leading adviser to General Curtis LeMay in designing the firebombing of Japan. He approached it as an accounting challenge and calculated that more destruction could be wrought if planes flew at a lower altitude, enabling them to hit more targets while also facing a greater risk of being shot down. More Americans and Japanese died as a result; the firebombing killed 100,000 people in Tokyo and brought mass destruction to more than sixty other Japanese cities. In The Fog of War McNamara acknowledges that he committed war crimes. “But what makes it immoral if you lose and not immoral if you win?” he asks. The question is left unanswered. (Fog of War)

Morrison decided on his course of action after watching and reading about all the children being killed in Vietnam by U.S. napalm and bombing. A friend and fellow Quaker noted that Norman had been praying for god’s will for himself and, in response to the criminal war in Vietnam, “he’d been writing letters to editors, to congressmen, to the President, and the Pentagon; he’d participated in demonstrations and protests . . . to try to convince people that what we were doing in Vietnam was wrong . . . but it hadn’t worked. And now he had to do something else . . . some dramatic gesture” Just where does that, as a political statement come from? Does it work? Can it accomplish political goals?

Self-immolation, is not supposed to be viewed as a terminal act of despair; it is a radical form of political protest designed to shock the moral consciousness of a nation. In 1965, as the Vietnam War escalated toward an industrialized slaughter, I had just graduated high school and to be perfectly honest, civil rights was more of an issue for me than Vietnam, even as it heated up and the draft came more into focus. There were all forms of dissent—marches, tax resistance, and petitions—but nothing shook the conscience more than the burning of the monk in 1963 but I suspect as a foreign event in a foreign culture in a faraway land, it did nothing to those in American politics.

Morrison's, on the other hand, had a dramatic effect on McNamara, especially as it occurred within 40 feet of his window. McNamara wrote: "Norman Morrison's action dramatized for me the tremendous discrepancy between the moral imperative-the prohibition on the killing of other human beings that I had subscribed to all my life- and what was occurring daily in Vietnam"' From that tragic moment on, McNamara changed gears. He continued to run the war, but he devoted more of his attention to negotiations. At his initiative, a month after the suicide, the USA decided on a 37-day bombing pause. "We thought we were acting in the interests of mankind, but the cost in lives was far greater than we or others had predicted." He realized by the time of his memoir that the US could have ended the war as early as 1962, ten years before it was finally concluded with an American retreat, if it had explored more fully non-military ways of achieving US goals. In that case we might have "saved our soul", he concluded.

Morrison was not the first Westerner to take this extreme form of political protest.   Alice Herz was the  first Western citizen to utilize self-immolation to protest the Vietnam War. Her sacrifice carried an immense theological and historical weight; as an 82-year-old refugee who had fled Nazi Germany, she was intimately acquainted with the cycle of state-sponsored destruction. Her act on March 16, 1965, in Detroit, was not merely a protest against a localized conflict but a witness against the recurring darkness of the 20th century. Although her act was initially under-reported because no immediate advocate stepped forward to tell her story, its significance as a precursor to Morrison's Pentagon witness cannot be overstated. But Herz's stated goals were broader.

She offered a searing critique of the billions appropriated for war through "hatred and fear." She explicitly linked the Vietnam conflict to the broader threat of nuclear proliferation, warning that the "Arsenal of Destruction—unlimited" would lead to global ruin unless the public was "awakened to action."  Herz performed her sacrifice with her mouth stuffed with cotton. This was to serve as a symbol of the marginalized voice of dissent, a physical manifestation of the inability of the people's plea for peace to penetrate the "Arsenal of Destruction."  While contemporary observers mischaracterized her act as a "collapse of hope," her private letters to her daughter, Helga, reveal a different motivation. Herz insisted her act was born "out of hope for mankind," a constructive attempt to inspire a "transnational solidarity" that bridged her European refugee experience with American and Japanese anti-war movements.

She set the stage for the specific "divine leading" that would soon consume Norman Morrison.

On November 2, 1965, Norman Morrison, a 31-year-old Baltimore Quaker, targeted the Pentagon to witness against the "impersonal, mechanistic thinking" of the Department of Defense. His choice of location was surgical; by igniting himself directly beneath the window of Secretary of Defense Robert McNamara, he brought the "fire of the Vietnamese village" to the epicenter of the American war machine. Morrison’s final day was marked by a haunting normalcy: he ate a lunch of French onion soup and grilled cheese sandwiches with his wife, Anne, and spent his final hours preparing notes for a New Testament class; he had been praying for guidance and on that day felt sure God was telling him what to do. Within the Quaker tradition, Morrison followed a "holy and compelling obedience" to a divine directive. This was not a rational political calculation but a response to the "Inward Light," which he believed demanded a sacrifice to awaken the numbed conscience of his compatriots.

Morrison was moved by an article in I.F. Stone’s Weekly detailing Father Currien’s account of a South Vietnamese village destroyed by American bombs. The image of women and children "blown to bits" was the immediate directive that compelled him to act for the "children in the priest's village."  He had read an article that morning about

Morrison’s decision to bring his 11-month-old daughter, Emily, to the Pentagon was startling to say the least. While his wife interpreted Emily as a "symbol of hope and survival," the vague references in his farewell letters to "Abraham’s sacrifice" suggest a darker, theological ambiguity—a radical questioning of whether the sacrifice of the innocent was the only language the Pentagon could understand. He had written a letter to his wife in which he describes having prayed for guidance, and this action was apparently the message he received from God. If you have ever been to Quaker Meeting, as I have many, many times, you'll understand how this personal relationship where God speaks directly to you is an important part.  I spoke once in Meeting, but it was less evidence of God speaking to me than me as a sanctimonious son-of-a-bitch. But the Elders loved it.

Witnesses watched as Morrison doused himself in kerosene and struck a match on his shoe, an act of grit and finality. He safely set Emily aside only moments before the flames took him, leaving a legacy that would haunt the institutional facade of the war for decades. (While Emily's clothes had been soaked in kerosene, she was set aside and not harmed.  One wonders if she hadn't been part of some Abrahamic delusion but changed his mind at the last minute.)

Morrison's protest successfully penetrated McNamara's psyche shattering the "overflowing confidence" of Secretary Robert McNamara. The protest was not merely a public relations crisis; it was a personal haunting that manifested in the physical and emotional deterioration of the McNamara family, with his wife and son developing ulcers from the stress of public accusations like "Baby burner!" and "Murderer!"

The moral justification for self-immolation rests on a philosophical paradox: using a final act of self-directed violence to witness against systemic external violence. The idea of "laying down one's life for his friends" is, of course, also a very military concept, i.e. throw yourself on the grenade to save your squad.,

The Society of Friends remains divided over this legacy. Some viewed it as a violation of the "pacifist testimony" against taking any life, while others saw Morrison as a "model Quaker" who followed the "Inward Light" , i.e. that of God in every man, to its ultimate, agonizing conclusion. Ultimately, these individuals believed that their self-sacrifice would save the lives of thousands of others.  

In the case of the Buddhist monk, it surely spelled the beginning of the end for the Diem regime; Herz's death, probably because there was so little press coverage, had almost no effect other than to encourage Morrison's suicide by fire.  Morrison's death clearly affected McNamara, but in the end, the sacrifices of these three didn't prevent many more years of war and the deaths of millions of people.

I have Craig McNamara's memoir on my list to read. McNmara's position on the war bitterly divided his family, and reviews suggest it's Craig way of coming to terms with that animosity. (McNamara, C. (2022). Because our fathers lied: A memoir of truth and family, from Vietnam to today. Little, Brown. )

Open letter to Secretary Noem

To: Secretary Kristi Noem,

Department of Homeland Security

From: Eric C. Welch

Date: February 7, 2026

Subject:  Arbitrary and Discriminatory Termination of Haiti’s Temporary Protected Status (TPS)

It is with profound dismay and moral urgency that this letter is issued in response to the recent decision by you to terminate Temporary Protected Status (TPS) for Haitian nationals. This action, grounded not in humanitarian principle or legal precedent but in inflammatory rhetoric and xenophobic sentiment, represents a grave betrayal of American values and international obligations.

Your decision to revoke TPS for over 350,000 Haitian individuals—many of whom have lived in the United States for over a decade, contributed to local economies, and raised American-born children—cannot be justified under any reasonable interpretation of public safety, national security, or immigration law. The cited justification of “reduced risk of harm” in Haiti is both speculative and disingenuous. As detailed in the U.S. District Court for the District of Columbia’s opinion in Miot v. Trump, No. 25-cv-02471 (ACR) (2026), the record shows a total disregard for the “perfect storm of suffering” currently documented in Haiti.

The legal standard for TPS revocation requires a good-faith evaluation of whether the conditions that led to the designation persist. Your decision fails this standard, relying instead on political expediency. While you claim conditions are "suitable for return," your own Department of State maintains a Level 4 "Do Not Travel" advisory due to kidnapping and civil unrest. To ignore a record of "staggering humanitarian toll" suggests a preordained agenda that bypasses statutory requirements.

Your public statements regarding Haitian immigrants—most notably your characterization of them as “killers, leeches, and entitlement junkies” from “damn countries”—are not merely inflammatory; they are a calculated effort to dehumanize a vulnerable population. Your remarks echo the worst traditions of anti-immigrant propaganda, drawing parallels to historical campaigns that justified exclusion and systemic oppression.

Furthermore, your assertions that Haitians are “coming here to take our jobs and our homes” are factually indefensible. TPS holders are vital economic contributors. Haitian TPS holders alone contribute approximately $1.3 billion in annual tax revenue. Far from being "leeches," 14.5% of TPS holders are entrepreneurs—a rate significantly higher than the 9.3% of the U.S.-born workforce. By terminating this status, you are choosing to turn law-abiding, tax-paying residents into an "unlawful" population overnight, perversely straining the systems you claim to protect.

Further, the public record of your personal history—specifically the decision to kill a companion animal under the pretext of behavioral issues—underscores a troubling pattern of disregard for life. The juxtaposition of this act with your public stance on Haitian TPS reflects a broader ethos: one that values control and dominance over compassion and human dignity.

The decision to end Haitian TPS is not just a policy failure—it is a moral failure. Your rhetoric has set a dangerous precedent that values political ambition over conscience. Every individual, regardless of origin, deserves safety, dignity, and the right to live without fear.

Sincerely,

Eric C. Welch

Economic Impact to Communities of AI, Robotic Replacement, and Immigrants

Recent announcements by Amazon and other major companies that they intended to layoff significant numbers of workers to be replaced by AI and robotics got me thinking of the economic impact to communities of these losses. The immediate impact is an increase in the stock price for the company, which makes the market happy, as the bottom line increases.  Beyond that, however, the salary and tax losses cause significant negative impacts on the communities where employees lived.

The surge in artificial intelligence adoption between 2024 and 2026 represents more than a technological milestone; it signals the definitive onset of what has been called the Fourth Industrial Revolution. Unlike previous industrial shifts that focused on physical mechanization, this era integrates "intelligence" directly into production via AI and blockchain, fundamentally threatening the labor-based tax models that have sustained modern social safety nets for nearly a century. "Nearly 3 in 10 companies said they’ve already replaced jobs with AI, and by the end of 2026, 37% expect to have replaced jobs with AI.(1). For example, Intel is replacing about 15,000 workers as they move to AI chip production and Amazon plans to reduce middle management and bureaucracy by using more AI. One source (2) reported that "leading U.S. corporations have announced significant layoffs in 2025 and early 2026, collectively affecting hundreds of thousands of employees. Many cuts have targeted corporate, technical, and administrative roles that companies believe can be streamlined through automation and AI tools. . . .Companies are widely investing in artificial intelligence to automate routine tasks and accelerate innovation. This has made certain jobs redundant — particularly in corporate services, customer support, and middle management. AI‑related cutbacks accounted for thousands of layoffs in 2025 alone, underscoring how technology adoption now directly influences employment decisions.

The transition to AI-driven organizational models creates impacts well beyond advantages to the corporation. When corporations replace taxable human payroll with automated systems, they capture "efficiency gains" that are currently untaxed at the source of labor. This creates an immediate deficit in federal and local social insurance programs and infrastructure spending, as the high-volume payroll taxes that fund the social contract are traded for corporate capital gains that lack equivalent redistributive mechanisms.

Federal benefits, such as Social Security and Medicare—operate on a "payroll tax dependency" model. These systems require a stable ratio of human taxpayers to beneficiaries to remain solvent. Approximately 50% of federal revenue is derived from income taxes, meaning the replacement of human workers with AI agents is an existential threat to the mathematical framework of these programs. Coupled with current administration policy to remove all immigrants regardless of status and a declining birth rate, the math becomes clear and inescapable.

The declining taxpayer-to-beneficiary ratio is reaching a critical breaking point. While the expansion of capital gains may benefit shareholders, it does not automatically replenish the Social Security Trust Funds, which are legally tethered to payroll contributions.

In 2024, AI created an estimated 119,000 direct jobs, such as AI engineering and data center construction, which technically exceeded explicit AI-related layoffs for that specific year. However, this equilibrium is a mirage.

The World Economic Forum (WEF) projects that 92 million jobs will become obsolete by 2030. The small volume of high-skill AI jobs cannot replace the lost tax revenue from millions of middle-management and operational roles.  Research indicates that for an automated economy to sustain the social safety net without human payroll, AI must be five to seven times more productive than current systems.

This productivity gap is the crux of the solvency crisis. New high-tech jobs are a temporary reprieve, not a solution. Unless AI productivity reaches that 5–7x threshold and policy levers are adjusted to capture that value, federal social insurance programs face an accelerated timeline to insolvency, as the tax base evaporates faster than the aging population exits the workforce. Coupled with an enormous decline in revenue lost from taxes paid by undocumented workers, (4) and the future becomes even bleaker.

Impact on local communities is substantial.  In 2026 the shift to AI systems in agriculture is having severe impacts on communities.The direct cost is the displacement of migrant and seasonal labor. A strawberry harvester can replace 15-30 workers. Most of those workers lack unemployment insurance, access to retraining, and mental health support.Indirect costs drain the resources of rural communities who host these workers about 4-8 months during the year. Seasonal workers spend a large percentage of their earnings on clothing, food, and supplies.  Without them local stores lose up to 40% of their annual income. Seasonal housing becomes vacant and falls intro disrepair. School enrollment falls leading to less assistance from the state. For every $1000 in wages lost, $1400 in economic activity is lost to the community. (5)

 A 2025 study from the Richmond Fed notes that for every high-wage job lost, there is a "downstream" decline in local service jobs. Displaced workers stop spending at local restaurants, gyms, and retail stores, causing a second wave of layoffs in the service sector. As property values potentially decline and income tax revenue drops, the local government’s ability to fund schools and infrastructure is weakened, which can lead to a "death spiral" for small manufacturing towns. (9)

Solutions are not obvious. The central tension for fiscal policy is capturing automation-driven value without stifling the innovation essential for competitiveness. The debate centers on the "Robot Tax" versus broader corporate reform. Andrew Yang, Bill Gates, and others have suggested taxing robots. (7) Others recommend a focus on taxing productivity gains as making more sense.

Defining a "robot" is technically complex. When we think robot we envision those magnificent, unstoppable machines in auto factories that do everything better and faster without asking for time off or bathroom breaks. But ISO 8373 defines industrial robots much more broadly, as "reprogrammable, multipurpose manipulators," this fails to account for software-based automation like Microsoft Word’s grammar check or accounting algorithms. Taxing physical machines creates a disproportionate burden on manufacturing while exempting the service sector’s digital automation. Taxing the machine is elusive.

Overall, robots have a mixed effect: replacing jobs that relatively high-wage manufacturing employees used to perform, while also making firms more efficient and more productive, an MIT article reported (8) Some areas are most affected by the mixed impact of robots. “In the U.S., especially in the industrial heartland, we find that the displacement effect is large,” he said. “When those jobs disappear, those workers go and take other jobs from lower wage workers. It has a negative effect, and demand goes down for some of the retail jobs and other service jobs.

Automation fundamentally shifts the infamous Laffer Curve.(6) In a human-only economy, tax revenue peaks at a certain rate; however, automation shifts this curve upward and rightward. Because machines do not require incentives to work and increase productivity margins, the state can responsibly increase corporate tax rates to achieve a higher peak of total tax collection than was possible in the pre-automation model, without losing the incentive for firms to automate. The superior alternative is to treat automation as a driver for higher corporate tax rates on efficiency gains, ensuring that the shift from labor to capital does not result in a net loss to the public treasury.

The systemic bias where capital investment in software/equipment is taxed at approximately 5%, while labor is taxed at over 25% needs to be addressed. Eliminating this disparity removes the artificial tax incentive for firms to automate solely for tax avoidance.

Companies received substantial tax benefits by agreeing to build in a community, often promising wildly optimistic predictions of the number of jobs that will be created. Communities should require that any tax benefit be reduced in proportion to any lessening of the number of jobs created. For example, if a company promises 1000 new jobs but only 500 result, the tax benefit would be reduced by 50%.

Policymakers must aggressively decouple social funding from human labor to prevent the collapse of the nation-state model and ensure that the wealth of the "machine economy" is reinvested into the human economy.

(4)According to 2024 and 2025 reports from the Institute on Taxation and Economic Policy (ITEP) and the Tax Policy Center, undocumented immigrants contribute billions annually:

  • Total Annual Contributions: Undocumented immigrants paid approximately $96.7 billion in federal, state, and local taxes in 2022.

  • Federal Payroll Taxes: About 50% to 75% of undocumented workers have federal taxes withheld from their paychecks. This includes Social Security and Medicare taxes, even though these workers are generally ineligible to receive the benefits they fund.

  • State and Local Taxes: Beyond income tax, undocumented residents pay sales taxes on purchases and property taxes (either directly as homeowners or indirectly through rent paid to landlords).

  • Economic Impact: A 2025 study noted that in 40 U.S. states, undocumented immigrants actually pay a higher effective tax rate than the top 1% of households in those states.
