The US federal budget goes to:

(based on FY 2025 budget proposal )

category, billions, % of federal spending

Social Security 1,543 21.2%

Medicare 936 12.9%

Medicaid 589 8.1%

Food Stamps (SNAP) 94 1.3%

WIC 8 0.1%

Section 8 33 0.5%

Defense 900 12.4%

Other Entitlement Programs 1,168 16.1%

Other Agencies (Non-Defense Discretionary) 1,029 14.2%

Where's interest payments?

Based on their omission I assume you're computing these numbers with them split out but it hardly seems fair to say you're spending "900" on defense when the total cost of paying that "900" is going to be much more since you had to borrow.

It's like saying a house only costs 1M when you end up paying over 1M in interest as well as the principal for 2M.
