The spending documented in Section IV represents direct war operations. Combat ends, but costs continue. Veterans require medical care for decades. Families receive survivor benefits for lifetimes. Interest accrues on borrowed war funds regardless of outcomes. These costs are legally obligated. They will be paid whether or not the wars achieved their stated goals. The bills for regime-change operations extend far beyond the years of active conflict.
All figures below are expressed in 2024 dollars and represent current projections based on existing obligations.

Veterans Medical Care and Disability Compensation
When service members are injured in war, the government assumes responsibility for their medical care and financial support for the rest of their lives. This includes treatment for physical injuries, mental health care, rehabilitation services, and monthly disability payments.
A service member wounded at age 22 in 2003 will require medical care and disability payments until 2070 or beyond. The cost of that care grows each year with medical inflation.
For post-9/11 wars, the Department of Veterans Affairs projects these costs through 2050:
| Cost Category | Projected Total (2024–2050) |
|---|---|
| Medical care for post-9/11 veterans | $2.2 trillion |
| Disability compensation | $1.1 trillion |
| Total veterans care | $3.3 trillion |
These figures cover only the next 26 years. Many veterans will require care beyond 2050. The youngest post-9/11 veterans are currently in their thirties and forties.
Over 1.8 million post-9/11 veterans currently receive disability compensation. Nearly 950,000 have been diagnosed with service-connected mental health conditions including PTSD and traumatic brain injury. These conditions require decades of ongoing treatment.
Survivor Benefits
When a service member dies in combat or from service-related causes, the government provides financial support to surviving family members. These payments continue for years or lifetimes, depending on the benefit type.
Survivor benefits include:
- Death gratuity: $100,000 paid immediately to the family of each service member who dies on active duty. For 7,057 deaths in post-9/11 wars, this totaled $706 million.
- Dependency and Indemnity Compensation (DIC): Monthly payments to surviving spouses, children, and dependent parents. Surviving spouses receive approximately $1,612 per month for life or until remarriage. Children receive payments until age 18 (or 23 if in school).
- Education benefits: The Fry Scholarship provides full college tuition and housing allowances to children and spouses of service members who died on active duty.
For 7,057 military deaths, if half of deceased service members left surviving spouses who live an average of 40 more years, DIC payments alone would total approximately $2.7 billion (not adjusted for future inflation). This excludes payments to children and parents, and excludes education benefits.
Total survivor benefit obligations for post-9/11 wars are estimated between $4 billion and $6 billion over the lifetimes of current beneficiaries.
Interest on War Borrowing
The United States did not raise taxes to pay for post-9/11 wars. The wars were financed through deficit spending—borrowed money.
Borrowed money accrues interest. That interest must be paid by taxpayers, regardless of whether the wars succeeded or failed.
According to the Costs of War Project, interest already paid on post-9/11 war borrowing through 2023 totaled approximately $2.5 trillion. Future interest obligations will continue as long as the borrowed principal remains unpaid.
By 2050, estimated interest costs on post-9/11 war spending will reach $6.5 trillion. This figure assumes current interest rates and moderate deficit reduction. If interest rates rise or deficits grow, the number increases.
Interest payments do not fund veterans care, infrastructure repair, or any other public service. They are the cost of having borrowed the war funds in the first place.
Total Long-Term Obligations
The following table summarizes long-term costs for post-9/11 regime-change wars through 2050:
| Cost Category | Amount (2024 dollars) |
|---|---|
| Direct war spending (through 2022) | $2.9 trillion |
| Veterans medical care and disability (2024–2050) | $3.3 trillion |
| Survivor benefits (lifetime obligations) | $4–6 billion |
| Interest on war borrowing (through 2050) | $6.5 trillion |
| Total costs through 2050 | $12.7+ trillion |
Returns to American public: U.S. revenue: $0 Additional oil supply: none Preferential pricing: none
The cost ratio continues beyond 2050. Veterans born in the 1980s and 1990s will require care into the 2060s and 2070s. Interest on unpaid war debt will continue indefinitely until the principal is repaid.
War costs compound across generations. Combat lasted years. Payment will last lifetimes.
