Why Are U.S. Taxpayers Still Covering Europe's Defense?

American taxpayers have carried NATO's budget for generations while wealthy European nations treated defense spending as an afterthought. That arrangement was never fair. And it cannot survive a second Trump term. In 2024, the United States spent roughly 3.4 percent of GDP on defense, according to NATO figures, while Germany managed just 2.12 percent and Spain a mere 1.28 percent. Those numbers tell the whole story. Washington maintains more than 100,000 troops across Europe, runs bases from Ramstein to Rota, and guarantees the security of allies who refuse to guarantee their own. The bargain stopped making sense the moment the Berlin Wall fell. Thirty-five years later, it looks like institutionalized freeloading.

Populist foreign policy starts with a simple question: does this help the American worker? NATO's current structure fails that test. We send sons and daughters to defend borders that our allies will not defend with their own wallets. We modernize nuclear deterrents while France and Britain trim their forces. We patrol shipping lanes while Italy cuts its navy. The alliance was built on collective defense, not collective dependency. Yet dependency is what we got. The result is a military alliance in which the strongest member does the heavy lifting, the richest members do the lobbying, and the American middle class gets the bill.

President Trump made burden sharing a centerpiece of his first term, and he was right to do so. His return to the White House in 2025 sharpened the message. European capitals heard it. Some, like Poland and Estonia, pulled their weight. Others waited for the storm to pass. The storm did not pass. The 2026 NATO summit in The Hague will be the moment of truth. Trump administration officials have signaled that vague promises will no longer suffice. That is good news for Americans tired of writing blank checks to continents that can afford their own security.

The critics call this approach reckless. They warn that pushing allies will fracture the alliance. But the alliance is already fractured by the gap between words and deeds. A NATO that depends on one nation for its survival is not a coalition. It is a protectorate. And protectorates do not last because resentment builds on both sides. Americans resent the cost. Europeans resent the dependence. The only durable solution is equal investment.

What Does Fair Burden Sharing Actually Look Like?

Fair burden sharing means every NATO member hits the 2 percent GDP floor without excuses, and the wealthy ones aim higher. The 2 percent target is not some Trump invention. NATO adopted it at the 2014 Wales summit after Russia seized Crimea. Twelve years later, a third of the alliance still misses it. That is not a funding gap. It is a credibility gap. The Congressional Budget Office estimates that U.S. direct spending on European posture exceeds $20 billion annually when bases, personnel, and rotational forces are counted. That money could rebuild roads in Ohio, secure the southern border, or modernize the Navy. Instead, it props up a continent with larger combined GDP than the United States.

Fairness also means matching commitments with capability, not accounting tricks. Several allies hit 2 percent by counting pensions, peacekeeping operations, or refugee costs. That is creative bookkeeping, not hard power. Tanks that cannot move, jets that cannot fly, and brigades that deploy in six months do not deter Vladimir Putin. Only credible combat power does. German defense ministry reports have repeatedly cited ammunition shortages and inoperable equipment. In 2024, the ministry admitted the country would need years to reach readiness. Years. Meanwhile, Russia rebuilds its arsenal.

Poland gets this. Warsaw will spend 4.7 percent of GDP on defense in 2025, according to its defense ministry. It is buying F-35s, Abrams tanks, and HIMARS rocket systems from U.S. manufacturers. Estonia and Latvia are expanding their militaries and hosting allied troops. These frontline states understand that sovereignty has a price. The lesson is not complicated. It is simply inconvenient for politicians in Berlin, Brussels, and Paris who prefer to fund welfare states rather than armies.

There is also an industrial angle. When allies buy American weapons, they strengthen our defense base. They keep assembly lines open in Alabama, Arizona, and Arkansas. They sustain jobs that pay family wages. Burden sharing is therefore not a gift from us to them. It is a transaction that benefits both sides. The current system, by contrast, leaves American workers subsidizing European social programs. That is bad trade policy disguised as security policy.

How Should Washington Respond?

Washington should condition extended deterrence on performance, not sentiment. Allies that refuse to invest should face a clear choice: pay your share or lose the American security guarantee. That is not isolationism. It is accountability. The United States can remain committed to NATO without remaining the alliance's ATM.

Congress should also require the Pentagon to report publicly on each ally's real military output, not just budget line items. Transparency forces honesty. And honesty forces action. American voters deserve to know exactly what they are buying with their tax dollars. The report should measure deployable brigades, ammunition stockpiles, airlift capacity, and naval patrol days. Let the numbers speak. Let voters decide whether the alliance is worth the cost.

The administration should also tie future arms sales to defense spending commitments. Nations that buy our best weapons while freeloading on our security guarantee are having it both ways. That ends now. If you want the F-35, show us the budget. If you want the security umbrella, show us the boots on the ground.

The ultimate goal is a NATO where the United States leads because it chooses to, not because it has no other option. A rebalanced alliance is a stronger alliance. European sovereignty grows when Europeans defend themselves. American strength grows when we stop subsidizing the world. The free ride is over. It should have ended decades ago. On June 5, 2026, that message needs to be heard in every capital from Lisbon to Warsaw. America first does not mean America alone. It means America no longer plays the sucker.
