U.S. Spent $5.6 Trillion on Wars Since 9/11, More Than Three Times What Pentagon Estimates

A new report shows that the true costs of war are much higher than reported by the Pentagon.


A report based at Brown University’s Watson Institute for International and Public Affairs finds that an average American taxpayer has spent $23,386 on post-9/11 wars. By the end of the fiscal year 2018, the overall U.S. spending on wars in Iraq, Syria and Afghanistan could reach $5.6 trillion. 

The report comes from the “Costs of War” project, whose international team of 35 scholars, human rights activists, physicians and legal experts research and facilitate debate about the ongoing expense of war. 

Neta Crawford, Costs of War co-director, and a professor of political science at Boston University, laid out how they arrived at the overall expenditure figures:

“The U.S. wars in Iraq, Syria, Afghanistan and Pakistan, and the increased spending on homeland security and the departments of defense, state and veterans affairs since the 9/11 attacks have cost more than $4.3 trillion in current dollars through fiscal year 2017,” explained Crawford. “Adding likely costs for fiscal year 2018 and estimated future obligations for veterans’ care, the costs of war total more than $5.6 trillion.”

Besides the spending by various government departments, the report also accounts for the cost of interest that the U.S. has paid so far on the money it borrowed to pay for the wars. These kind of figures are not counted in Pentagon’s reports on war costs, say the researchers. 

For instance, the report ““Estimated Cost to Each Taxpayer for the Wars in Afghanistan, Iraq and Syria” calculated the U.S. costs in those wars to be only $1.52 trillion, saying each taxpayer’s burden amounted to $7,740 as it only included spending by the Department of Defense.

Catherine Lutz, project’s co-director and a professor of international studies and anthropology at Brown University, remarked that it’s important for Americans to know the real amounts their country spends on wars, especially as they are likely to keep getting larger and larger.

“The American public should know what the true costs of these choices are and what lost opportunities they represent,” said Lutz. “Given that the current administration has announced more years of war in Afghanistan and elsewhere, this total will only grow.”

Lutz also pointed out that “optimistic assumptions” and a “tendency to underestimate and undercount” the genuine spending on such wars are characteristic of estimates of the budgetary costs.

The reason interest was included in the report is because the wars have largely been paid by borrowing rather than new taxation or making cuts. Even if the U.S. stopped spending on the wars now, the cumulative interest costs could add more than $7.9 trillion to the national debt in the next several decades, said Crawford.

“Thus, even if military spending plateaus, interest costs will far surpass total war costs unless Congress devises another plan to pay for the wars, for instance by selling war bonds or increasing taxes,” she added.

While the Costs of War report does take into account expenditures like health care and disability payments to veterans, there are still billions in unaccounted-for costs from a variety of sources like money spent by state and local governments to the donations of excess military equipment the U.S makes to countries in war zones.

The report also doesn’t include money the U.S. spends on counter-terrorism activities in dozens of countries, its operations in the Horn of Africa, Uganda, Trans-Sahara, the Caribbean and Central America or the Department of Defense’s European Reassurance Initiative which is aimed at deterring Russia.

Yale scientists restore brain function to 32 clinically dead pigs

Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.

Still from John Stephenson's 1999 rendition of Animal Farm.
Surprising Science
  • Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
  • They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
  • The research raises many ethical questions and puts to the test our current understanding of death.

The image of an undead brain coming back to live again is the stuff of science fiction. Not just any science fiction, specifically B-grade sci fi. What instantly springs to mind is the black-and-white horrors of films like Fiend Without a Face. Bad acting. Plastic monstrosities. Visible strings. And a spinal cord that, for some reason, is also a tentacle?

But like any good science fiction, it's only a matter of time before some manner of it seeps into our reality. This week's Nature published the findings of researchers who managed to restore function to pigs' brains that were clinically dead. At least, what we once thought of as dead.

What's dead may never die, it seems

The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called BrainEx. BrainEx is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.

BrainEx pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.

The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if BrainEx can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.

As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.

The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.

"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told National Geographic.

An ethical gray matter

Before anyone gets an Island of Dr. Moreau vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.

The BrainEx solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness.

Even so, the research signals a massive debate to come regarding medical ethics and our definition of death.

Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?

"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told the New York Times. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."

One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.

The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, told Nature that if BrainEx were to become widely available, it could shrink the pool of eligible donors.

"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.

It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.

Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? The distress of a partially alive brain?

The dilemma is unprecedented.

Setting new boundaries

Another science fiction story that comes to mind when discussing this story is, of course, Frankenstein. As Farahany told National Geographic: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have Frankenstein, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."

She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.
