Debt Bomb Surpasses Pentagon

For the first time in American history, Washington is spending more to service its debt than to defend the country.

Story Snapshot

Annual interest on the national debt is now about $970 billion, more than the Pentagon’s entire budget.
Debt service has nearly tripled since 2020 and is projected to reach around $2 trillion within a decade.
Interest now rivals Medicare and trails only Social Security, crowding out core priorities conservatives care about.
Both parties’ past overspending and “kick the can” politics have pushed America toward a dangerous tipping point.

Debt Service Now Bigger Than the Pentagon

By the end of fiscal year 2025, the federal government will pay about $970 billion in interest on the national debt, more than the entire national defense budget.^[8] A Committee for a Responsible Federal Budget analysis finds that interest costs, at roughly $970 billion per year, already exceed what Washington spends on the Pentagon or Medicaid.^[8] That means more of your tax dollars now go to bondholders and big financial institutions than to our troops, ships, planes, and missile defense systems.

The Congressional Budget Office projected this crossover back in 2024, warning that interest outlays would surpass defense spending for the first time in modern history.^[3] The Committee for a Responsible Federal Budget later confirmed that net interest was on track to hit about $870 billion in 2024, above roughly $822 billion for national defense.^[5] What used to be a talking point from fiscal hawks is now a hard budget fact: the interest line item has leapfrogged the Pentagon and become one of Washington’s biggest bills.

How We Got Here: Low Rates, Big Spending, and a $38 Trillion Tab

America’s total national debt now sits around $38–39 trillion, after years of deficits under both Republican and Democrat administrations.^[8] Since 2020, interest payments have nearly tripled, rising from roughly $345 billion to close to $970 billion as higher rates hit a much larger pile of debt.^[5]^[8] As a share of our economy, interest costs have doubled in just a few years, from about 1.6 percent of national output to a record 3.2 percent in 2025.^[5]^[8] This is what happens when Congress treats low interest rates like free money and refuses to slow the growth of federal programs.

Nonpartisan analysts warn that interest will not level off on its own. The Congressional Budget Office and outside budget groups estimate that annual interest costs will more than double again over the next decade, reaching around $2.1 trillion by 2036 if current law stays in place.^[4]^[8] By then, interest alone could eat up roughly one quarter of all federal tax revenue.^[8] In simple terms, for every four dollars Washington collects, one would go just to stand still on past borrowing, not to border security, veterans, or infrastructure.

Interest Crowds Out Medicare, Defense, and Everything Else

Interest is no longer a small, background item in the budget; it is now one of the main drivers of federal spending growth. By 2025, interest became the third-largest federal expense, just behind Social Security and Medicare, and nearly matched Medicare’s roughly $997 billion in costs.^[4]^[7] Analysts expect interest to overtake Medicare as the second-largest line item by the end of this decade.^[5]^[8] That means debt service, not health care or defense, will shape what is left for every other priority conservatives care about.

As interest grows, it squeezes the parts of the budget Congress actually debates every year. A detailed review of recent spending shows that from 2019 to 2025, interest costs grew more than 150 percent, far outpacing increases in defense, Medicare, or Medicaid.^[4]^[7] Some estimates suggest interest already accounts for more than one-sixth of all federal spending, up from less than one-tenth just a few years ago.^[7] Every extra dollar going to creditors is a dollar not available for pay raises for service members, better equipment, border barriers, or relief for working families.

Why This Matters for National Strength and Conservative Priorities

Historians and budget experts warn that when great powers spend more on debt interest than on defense, they risk long-term decline.^[21] Research often called “Ferguson’s Law” links this pattern to falling military strength and shrinking global influence, as rising debt service crowds out national security investment.^[21]^[24] The United States crossed that threshold in 2024 and 2025, when interest spending edged above defense outlays, putting us in the same danger zone that hurt past empires.^[21]^[24] For conservatives who value peace through strength, this is more than a bookkeeping issue; it is a strategic warning.

Direct US costs for the ~108-day 2026 Iran conflict (late Feb to mid-June) are estimated at ~$113 billion. Pentagon briefings cited $11.3B in the first 6 days + ~$1B/day ongoing for munitions/ops. Other analyses range $25-72B mid-war. Broader factors like debt interest, extra…

Voters are starting to connect the dots. A 2025 poll from the Peterson Foundation found that more than three-quarters of Americans, including a large majority of Republicans, now see runaway borrowing as a direct threat to their financial future.^[7] Yet many officials and media voices still call the situation “manageable” because interest is a few percent of gross domestic product.^[6] That may comfort Wall Street, but it does nothing for families watching Washington send record sums to creditors while claiming there is “no room” for tax relief, border enforcement, or serious waste-cutting reforms.
