As he left Monday for the NATO summit in Ankara, President Trump posted his opening argument to Truth Social: the United States "spends more money on Nato than any other country, by far, to protect them, without getting any benefit from so doing" [1]. Two claims are packed in that line - that America pays for NATO far beyond anyone else, and that it gets nothing back. NATO keeps the numbers, and both claims come apart against them.
Start with what "money on NATO" actually means. The alliance runs a common budget - headquarters, missions, shared infrastructure - funded by a formula tied to each member's national income. For 2026 the United States pays 14.9 percent of it, the exact same share as Germany, out of a budget of roughly 5.3 billion euros [2][4]. That is about one seventh. It is not "by far" the most; it is tied for the top and was recently trimmed from 15.9 percent.

The number that makes America look like it carries NATO on its back is a different number entirely. The United States spent about 980 billion dollars on defense in 2025, roughly 60 percent of what all NATO members spent combined [2]. That is real, but it is not a NATO bill - it is the US military budget, which pays for American forces and priorities across the entire globe, from the Pacific to the Middle East, most of it unrelated to Europe. Folding all of it under "money on NATO" is how one seventh becomes "by far the most." And the share has been falling: US spending was 72 percent of the allied total in 2016 and 60 percent now, as other members increased their own [2].
Then the harder claim: "no benefit." NATO's core promise is Article 5, the pledge that an attack on one member is an attack on all. It has been invoked exactly once in the alliance's 76 years [3]. Not for a European country. For the United States - after the September 11 attacks, when the allies declared the assault on America an attack on all of them, and then sent troops who fought and died alongside US forces in Afghanistan for two decades [3]. The one time the mutual-defense clause was ever triggered, it was triggered to defend this country.
The context makes the framing more than a bookkeeping error. Trump is arriving in Ankara to press allies toward 5 percent of GDP on defense, and to decide how far the US keeps backing Ukraine - a country whose air defenses failed against Russian ballistic missiles that killed 11 people in Kyiv this week for want of interceptors [5]. "We pay by far the most and get nothing" is the argument for both squeezing allies and stepping back. It is a powerful argument. It is built on the wrong number and a history that runs the other way: America pays a seventh of the common budget, the same as Germany, and the alliance's single act of collective defense was to stand up for America.
