&quot;Well maybe it was true in early 90s&#x27; But today if you include mandatory (entitlems) or just discretionary spending budget in the pie. Mandatory spending is dominated by medical (medicare etc) and social security. So that part doesn&#x27;t sound right. Anyone know more?&quot;<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2013_United_States_federal_budget" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2013_United_States_federal_bud...</a><p>Defense was third, behind Medicare&#x2F;Medicaid and Social Security. So no, it&#x27;s not right. They may have been interpreting discretionary spending as the whole thing, in which case defense is the largest single piece.
