The War on Terror: $8T Later
Two decades. 940,000 dead. 37 million displaced. 80+ countries. Zero objectives fully met.
On September 11, 2001, 2,977 Americans died in the worst terrorist attack on US soil. In response, the United States launched what would become the most expensive, most far-reaching, and most catastrophic military campaign in modern history — a “war” with no defined enemy, no geographic boundary, no exit criteria, and no end. Twenty-five years and $8T later, there are more terrorist organizations in the world than when it started.

60 Words That Enabled 25 Years of War
On September 14, 2001 — just three days after the attacks — Congress passed the Authorization for Use of Military Force (AUMF). It was 60 words long. Only one member of Congress voted against it: Representative Barbara Lee of California, who warned it would be used as a “blank check.” She was right.
“That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.”— Authorization for Use of Military Force, Public Law 107-40, September 18, 2001
This single sentence — drafted in 20 minutes, debated for 3 days, intended for Afghanistan — has been used to justify military operations in at least 22 countries across the Middle East, Africa, and Asia. It was used to justify drone strikes in Yemen, special operations in Somalia, air campaigns in Libya, surveillance of American citizens, indefinite detention at Guantánamo, and military operations in countries that didn't exist as conflict zones on 9/11. No subsequent president has asked Congress for new authorization. Every one has used this 60-word sentence instead.
💡 Did You Know?
Representative Barbara Lee's lone “no” vote made her the target of death threats. She received armed security. Years later, both Republican and Democratic lawmakers acknowledged she was right — but the AUMF has never been repealed. As of 2026, it remains the legal basis for US military operations in countries most Americans couldn't find on a map.
From 1 Country to 80+
The War on Terror began as a response to 9/11, targeting Al-Qaeda in Afghanistan. It has since metastasized into a global military campaign spanning at least 80 countries — roughly 40% of all nations on Earth. The Costs of War Project at Brown University has documented US counterterrorism operations in:
Major Combat Operations
- • Afghanistan (2001–2021) — 20 years
- • Iraq (2003–2011, 2014–present)
- • Syria (2014–present)
- • Libya (2011, 2015–present)
- • Yemen (2002–present)
- • Somalia (2007–present)
- • Pakistan (2004–2018 drone campaign)
Special Operations & CT Missions
- • Niger, Mali, Cameroon, Chad — Sahel region
- • Philippines — Mindanao operations
- • Kenya, Uganda, Djibouti — East Africa
- • Jordan, Bahrain, Kuwait, UAE — Staging
- • 70+ additional countries — Section 127e programs, training missions, intelligence operations
As journalist Nick Turse documented, US special operations forces deployed to 149 countriesin a single year (2017) — 75% of the world's nations. Most of these deployments were never reported to the public or meaningfully debated in Congress. The “war” grew so large that most Americans have no idea where their military is fighting.

Civilians: 185,000–209,000 • Direct deaths only; Lancet and ORB surveys estimate 500K–1M+
Civilians: 46,000+ • Plus 70,000 Pakistani civilians from spillover
Civilians: 24,000+ • Drone strikes, military operations, militant violence
Civilians: 19,000+ • US-backed Saudi coalition; "worst humanitarian crisis" per UN
Civilians: 300,000+ • US role: arming rebels, airstrikes, proxy war
Civilians: 4,000+ • Drone strikes and special operations since 2007
Civilians: 10,000+ • 2011 NATO bombing; failed state ever since
Note on indirect deaths: For every person killed directly by violence, an estimated 3–4 die from the indirect effects of war: destroyed hospitals, contaminated water, disrupted food supply, displacement. The Watson Institute estimates the total death toll — direct and indirect — at 4.7 million people.

Including future interest on war debt
Every family of four in America has paid roughly $100,000 for the War on Terror — enough for a down payment on a house, four years of in-state college tuition, or a lifetime of healthcare premiums. Most of it was borrowed, meaning future generations will continue paying interest on wars their parents and grandparents fought. See your personal tax receipt →

The Outcomes
Afghanistan — 20 Years, $2.3 Trillion, Back to Square One
After 20 years and $2.3 trillion, the Taliban — the same group the US invaded to remove — returned to power in August 2021. The Afghan military the US spent $83 billion building collapsed in 11 days. 2,461 US troops died. 20,752 were wounded. At least 46,000 Afghan civilians were killed directly. Girls are again banned from school. The entire 20-year project evaporated in less than two weeks.
Iraq — No WMDs, 300,000+ Dead, ISIS Created
No weapons of mass destruction were found. The power vacuum created by the invasion and the disastrous decision to disband the Iraqi military (400,000 armed men sent home with no pay and no future) led directly to the rise of ISIS. Iran — the regime the US was supposedly containing — became the dominant power in Iraq. An estimated 300,000+ civilians died. Cost: $2.4 trillion.
Libya — Open-Air Slave Markets
After US-led NATO bombing removed Gaddafi in 2011, the country collapsed into a failed state with open-air slave markets. Weapons flowed across the Sahel, fueling insurgencies in Mali, Niger, Burkina Faso, and Nigeria. Obama later called it the “worst mistake” of his presidency.
Yemen — “World's Worst Humanitarian Crisis”
US support for Saudi Arabia's bombing campaign created what the UN called “the world's worst humanitarian crisis.” 150,000+ dead, millions facing famine. American bombs — with American targeting intelligence — hit school buses, weddings, and hospitals. The bomb fragments said “Made in USA.”
The Surveillance State
The War on Terror didn't just reshape the Middle East — it reshaped America itself. In the name of “national security,” the US government built the largest surveillance apparatus in human history.
The USA PATRIOT Act (2001)
Passed 45 days after 9/11 with almost no debate. Expanded FBI authority to access financial records, medical records, phone records, and internet activity — without a warrant. Section 215 was later used to justify the NSA's bulk collection of every American's phone records.
NSA Mass Surveillance (revealed 2013)
Edward Snowden revealed that the NSA was collecting metadata on every phone call made in America, reading emails, monitoring internet browsing, and tapping into the servers of Google, Apple, Facebook, and Microsoft through the PRISM program. Director of National Intelligence James Clapper lied to Congress about the program's existence — under oath.
Guantánamo Bay (2002–present)
780 men have been detained at Guantánamo. Many were held for years without charges. 731 have been transferred or released — most without ever being charged with a crime. As of 2025, 15 remain. The facility has cost over $13 million per detainee per year — making it the most expensive prison on Earth.

Since 2001, more veterans have died by suicide than in all post-9/11 combat operations combined. The youngest veterans — those aged 18-34 — die by suicide at 2.5× the rate of non-veterans. Many waited months for VA mental health appointments. The VA mental health budget is a fraction of what the Pentagon spends on a single aircraft carrier ($13 billion).
The long-term cost of veteran healthcare will exceed $2.2 trillion according to the Costs of War Project — and the peak hasn't arrived yet. Vietnam-era VA costs peaked 40 years after that war ended. The true cost of Iraq and Afghanistan won't be known until the 2060s.
Who Profited: The Contractors
While 7,057 US troops died and millions of civilians were killed, defense contractors posted record profits year after year. The War on Terror was the most profitable event in the history of the arms industry.
War on Terror contracts: $200B+
F-35, missiles, C-130s — largest defense contractor on Earth
War on Terror contracts: $150B+
Tomahawk missiles ($2M each), Patriot systems, surveillance tech
War on Terror contracts: $130B+

💡 Did You Know?
Vice President Dick Cheney was CEO of Halliburton before taking office. Halliburton's subsidiary KBR received $39.5 billion in no-bid contracts during the Iraq War. Cheney retained stock options worth millions. When asked about it, he said it was “not relevant.” The contracts were later found to have overcharged the government by hundreds of millions of dollars.
The Drone Wars
The War on Terror pioneered a new form of warfare: death by remote control. From an air-conditioned trailer in Nevada, operators killed people in Pakistan, Yemen, Somalia, Libya, and Syria — without congressional debate, judicial review, or meaningful public accountability.

President Obama — awarded the Nobel Peace Prize in 2009 — authorized 10× more drone strikes than George W. Bush. He maintained a personal “kill list” reviewed every Tuesday, including the name of at least one American citizen (Anwar al-Awlaki, killed in Yemen in 2011 without trial). Trump then revoked Obama's executive order requiring public reporting of civilian casualties, making the program even less accountable.
“In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex.”
— President Dwight D. Eisenhower, Farewell Address, 1961
“War is a racket. It always has been. It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one in which the profits are reckoned in dollars and the losses in lives.”
— Major General Smedley Butler, War Is a Racket, 1935
“Of all the enemies to public liberty, war is, perhaps, the most to be dreaded, because it comprises and develops the germ of every other. War is the parent of armies; from these proceed debts and taxes; and armies, and debts, and taxes are the known instruments for bringing the many under the domination of the few.”
— James Madison, 1795
Did It Make Us Safer?
The number of terrorist organizations worldwide has increased since 2001. The number of countries experiencing significant terrorism has increased. Al-Qaeda, which the entire war was supposed to destroy, still exists — in more countries than in 2001. The Taliban, which we spent 20 years fighting, runs Afghanistan again. ISIS, which didn't exist before the Iraq War, rose from the chaos we created.
The State Department's own annual terrorism reports show a steady increase in terrorist attacks worldwide since 2001. A RAND Corporation study found that military force was the least effective method of defeating terrorist organizations — political accommodation and policing were far more successful.
We spent $8T. We killed 940,000 people. We displaced 37 million. We destabilized a region. We shredded civil liberties. We created new enemies. And the threat is still here — arguably worse than when we started.
💡 Did You Know?
- • The War on Terror cost more (inflation-adjusted) than World War I, the Korean War, and the Vietnam War combined.
- • If you stacked $8T in $100 bills, the pile would be 5,400 miles tall — roughly the distance from New York to Tokyo.
- • The US has spent more on air conditioning for troops in Iraq and Afghanistan ($20B/yr) than NASA's entire annual budget.
- • More Americans have been killed by gun violence at home since 9/11 (~550,000) than in all post-9/11 wars (~7,000 combat deaths).
- • The 2001 AUMF has been cited to justify operations in 22 countries — 19 of which had nothing to do with 9/11.
- • The Pentagon has never passed an audit. In its 7th consecutive failed audit (2024), auditors couldn't account for $3.8 trillion in transactions.
The Bottom Line
“Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed.”— President Dwight D. Eisenhower, “Chance for Peace” speech, 1953
The War on Terror is the defining catastrophe of 21st-century America. It consumed $8Tthat could have transformed American life — free college, universal healthcare, rebuilt infrastructure, clean energy. Instead, it killed 940,000 people, displaced 37 million, created new terrorist organizations, enabled mass surveillance of American citizens, enriched defense contractors, and left veterans to kill themselves at a rate of 17 per day.
The war was authorized by 60 words, written in 20 minutes, that have been stretched across 25 years, 80+ countries, and 4 presidential administrations. It was launched to fight one terrorist organization in one country. It became a global, permanent, self-perpetuating war machine that creates the very enemies it claims to fight.
It is the most expensive failure in American history. And it's still going.
