- Al Jazeera analysis using TheDataProject.AI's WarCosts archive estimates major US wars since 1950—in Korea, Vietnam, Iraq, and Afghanistan—have directly killed nearly 4.5 million civilians and cost more than $5.7 trillion, not counting deaths from lost food, healthcare, or proxy conflicts.
- The Iran war cost an average of $1.88 billion per day during its first six days—nearly triple the daily cost of the Iraq War—according to the Pentagon, with analyst Stephen Semmler of the Center for International Policy estimating $28.7 billion in just the first two weeks.
- Civilian deaths in Iran reached 1,701 in the war's first 40 days, averaging 43 per day—nearly double the daily rate in Afghanistan—according to the Human Rights Activists News Agency.
- The Iran war's unpopularity is historically extreme: 60% of Americans disapproved by April 12, compared with just 9% for Afghanistan, 23% for Iraq, and 24% for Vietnam at their respective starts.
- Pentagon comptroller Jules Hurst told Congress the war has cost about $25 billion so far, a figure Rep. Ro Khanna called "totally off"; the Trump administration has requested an additional $200 billion in military funding from Congress.
- Brown University's Costs of War research projects an additional $2.2 trillion in US veteran care costs through 2050 for post-9/11 wars alone—on top of the $5.7 trillion already spent.
- Sen. Bernie Sanders noted the nearly $8 trillion spent on these wars could have funded a century of free four-year public college for every American, 400 years of global clean drinking water, or 200 years of universal pre-K.
Why it matters: The $5.7 trillion price tag and 4.5 million civilian deaths—excluding US-backed conflicts in Yemen and Gaza—frame every new US military venture as carrying costs that compound across generations, including a projected $2.2 trillion in post-9/11 veteran care alone. With the Iran war burning through $1.88 billion per day and 60% public disapproval within weeks, taxpayers are funding a historically expensive and historically unpopular conflict with no off-ramp visible in the data.
