WASHINGTON – Global defense expenditures reached $2.6 trillion in 2025, with the United States shouldering over a third of that financial burden, according to data compiled by the International Institute for Strategic Studies. The American defense budget, approaching $1 trillion, is more than three and a half times larger than the reported spending of China, its nearest geopolitical competitor.
Paying for Global Primacy
The staggering figure underscores the immense cost of maintaining American military hegemony. While Washington prioritizes precision weapon systems, power projection, and technological overmatch, the financial strain is borne entirely by the American taxpayer. President Trump’s proposal to further increase the annual defense outlay to $1.5 trillion would represent a massive allocation of national resources away from domestic industry and infrastructure.
This spending spree, often justified by citing threats from Beijing, secures supply chains for major defense contractors whose lobbying efforts ensure budget lines remain bloated. The cost of maintaining a single technologically advanced aircraft, for instance, often eclipses the initial procurement price, creating a perpetual cycle of spending that benefits the defense industry more than the warfighter's readiness.
"Readiness is very expensive, and perishable. A country's on-paper investment doesn't always translate directly into military capability," said Mark Cancian, a senior advisor at the Center for Strategic and International Studies, noting that maintenance and training often get overlooked.
NATO Allies and Economic Realities
While the U.S. bankrolls its own defense, it continues to pressure NATO allies to meet spending targets. A new goal pushed by the Trump administration aims for allies to spend 5% of their GDP on defense by 2035. For American workers, however, the question remains whether sending billions abroad for collective security arrangements serves the national interest as effectively as reinvesting those funds in domestic industrial capacity and border security.
The report highlights the disconnect between spending and actual security. While Ukraine is forced to devote over 20% of its GDP to its military to sustain its national sovereignty, the American homeland is not under the same conventional threat, raising critical questions about the nation's true defense needs versus its global intervention posture.
