Major US Wars Since Korea Killed Over 4 Million Civilians, Cost Nearly $6 Trillion: Analysis
It estimates that major US military engagements since 1950—in Korea, Vietnam, Iraq, and Afghanistan—have directly cost the lives of nearly 4.5 million civilians and more than $5.7 trillion.
The data, collected into a sprawling open-source WarCosts archive maintained by TheDataProject.AI, comes from a variety of government reports, peer-reviewed academic research, and investigative organizations.
The civilian casualty number notably only includes those directly caused by the wars themselves, not those caused by the resulting losses of food, healthcare, or war-related diseases. It also does not include the lives lost in proxy conflicts funded by the US, Saudi Arabia's brutal war in Yemen, which resulted in an estimated 150,000 violent civilian deaths between 2015-22, or Israel's more than two-year genocidal war in Gaza, which has resulted in at least over 75,000 deaths, and likely many more.
The dollar figure, meanwhile, does not include the additional $2.2 trillion the US is expected to spend caring for veterans of the post-9/11 wars until 2050, according to Brown University's Costs of War research series.

Even compared with the staggering figures throughout US history, the cost of the war in Iran so far is uniquely high.
The Pentagon estimated that during just the first six days of the war, the US government spent an average of $1.88 billion per day, nearly three times the daily cost of the next most expensive major conflict, Iraq.
On Wednesday, Pentagon comptroller Jules Hurst told Congress that the Iran War had cost about $25 billion in total since it began two months ago. But many critics, including Rep. Ro Khanna (D-Calif.), have suggested that this number is "totally off" and the cost is likely much higher.
Stephen Semmler, a data analyst and senior fellow at the Center for International Policy, estimated based on statements from officials, federal procurement and operations data, and reporting on military deployments and armaments use that by March 13—just two weeks into the conflict—the war had already cost about $28.7 billion, over $2.1 billion per day. This analysis included the military's operational costs, the costs of weapons, damage to US military assets, and subsidies to Israel.
The Trump administration has reportedly requested an additional $200 billion in military funding from Congress for the war.
The war in Iran resulted in 1,701 civilian deaths during its first 40 days, according to the US-based Human Rights Activists News Agency, equivalent to about 43 per day—nearly double the number killed per day in Afghanistan.

What distinguishes the Iran War from previous US military adventures is its staggering unpopularity. At its start, polls showed 43% of Americans disapproved of Trump's decision to launch the war. Disapproval had jumped to 60% as of April 12.
With the exception of the Korean War, which began very unpopular and gained approval over time, no other major US conflict has begun with so little backing from the US public—just 9% disapproved of the Afghanistan War when it began, 23% disapproved of Iraq, and 24% disapproved of Vietnam, and it took years for the majority of the public to turn against them.

The WarCosts data center estimates that the nearly $8 trillion spent on these major wars could have paid for a century of four-year public college for every American, 400 years of clean drinking water for everyone on Earth, or more than 200 years of universal pre-K for every child.
Citing a recent expert estimate that the Iran War could cost $1 trillion if it goes on for a decade, Sen. Bernie Sanders (I-Vt.) lamented in a social media post that "somehow, there is always money for war, but never enough money for housing, education, or the needs of working people."
The senator said, "We must and will change our national priorities."
New Federal Data Confirms: Trump's War of Choice in Iran Is a 'Disaster' for US Economy
The BEA estimates that US consumer spending increased by $195.4 billion in March—with "gasoline and other energy goods" making up $81.3 billion of that total. Trump's war on Iran has hurled the global energy market into chaos, pushing US gas prices above $4 per gallon on average.
BEA also released data showing that US gross domestic product rose at at an annual rate of 2% during the first three months of 2026—a smaller rebound than expected after the final quarter of 2025, when GDP rose by just 0.5%.
Additionally, the Bureau of Labor Statistics on Thursday released its Employment Cost Index for the first quarter of 2026. The index, which measures wages and benefits paid to workers, increased 0.9%—well behind PCE inflation.
"Paychecks are lagging behind prices, and economic growth remains sluggish thanks to the president’s gross mismanagement," said Jacquez. "Working families looking for relief certainly won’t find it under this administration. It’s no wonder Trump’s economic disapproval ratings are at an all-time high."
Rep. Brendan Boyle (D-Pa.), the top Democrat on the House Budget Committee, said in a statement Thursday that "Trump promised to lower costs on day one, but today’s report is more proof that was just a lie."
"His so-called ‘Big Beautiful Bill,’ his reckless tariffs, and his war of choice in Iran are driving up costs on everything from groceries to gas to healthcare," said Boyle. "Republicans control the White House, the House, and the Senate, and they only have themselves to blame for this cost-of-living crisis. The American people deserve better than their chaos, corruption, and total economic incompetence.”
