What percentage of the money has the US paid historically? Can you give me the averages grouped by the current President over the past 40 years?
The US has paid roughly 65–70% of NATO's combined defense bill for most of the past 25 years, but the share was lower during the Cold War when European allies spent more, and is now falling toward ~62% as European budgets surge.
Why it matters: The declining US share — driven by European rearmament, not US cuts — undercuts the 'freeloading' framing, even as Hegseth uses it to press for more.
- Reagan era (1985–1989): US share of NATO total was roughly 50–55%; European allies were still spending heavily on Cold War–era forces, and the US itself was near 6% of GDP on defense.
- G.H.W. Bush & Clinton (1989–2001): The 'peace dividend' hit Europe harder than the US — European budgets fell faster, pushing the US share upward toward 60–65% through the 1990s.
- G.W. Bush (2001–2009): Wars in Afghanistan and Iraq drove US defense spending to its post-Cold War peak; the US share of NATO totals climbed to roughly 70–73%, the highest since the Cold War.
- Obama (2009–2017): US spending fell as wars wound down, but European allies cut even more aggressively; the US share held near 65–70% through this period.
- Trump I (2017–2021): US share stayed near 70%; Trump's pressure nudged some European allies to start spending more, but the aggregate barely moved.
- Biden (2021–2025): Russia's 2022 invasion of Ukraine triggered a sustained European buildup; by 2023 the US share was 68.7%, still dominant but trending down.
- Trump II (2025–present): European spending jumped ~20% in 2025 alone; the US share has fallen to roughly 62% of NATO's combined $1.59 trillion total — the lowest in decades.
- CSIS cautions the 70% figure is misleading: the vast majority of US defense spending covers global commitments (Pacific deterrence, power projection) not specific to European defense.
Room for disagreement
- The '70% share' metric is contested. CSIS argues it counts US spending on Pacific fleets, nuclear deterrence, and global force projection as 'NATO burden' — so it vastly overstates what the US actually spends defending Europe specifically versus pursuing its own global interests.
- Some analysts (Heritage Foundation, Hegseth camp) accept the raw spending-share figure at face value as proof of European freeloading; others (RAND, CSIS) say capability contributions — troops, bases, intelligence — require a broader accounting that makes the gap look smaller.
