The United States spends more on national defense than the next ten countries combined. It maintains military bases across more than 70 nations. It underwrites the security of allies in Europe, Asia, and the Middle East who have, for decades, spent their own defense savings on social programs and domestic priorities.

With the national debt now past $39 trillion, this arrangement deserves serious conservative scrutiny.

The America First Case on Defense Spending

The Trump administration has made burden-sharing a central demand of its foreign policy — and rightly so. NATO’s 2% of GDP defense spending target, which most European members ignored for years, is not an arbitrary number. It is the minimum threshold required for a credible collective defense.

For too long, American taxpayers have subsidized European security while European governments built welfare states they could not have afforded had they paid their own defense bills. That subsidy has not been free. It has contributed to an American defense budget that, while necessary, is also a significant driver of annual deficits.

The Trump administration’s pressure on NATO allies to meet their spending commitments is the right policy — not because America wants to abandon its allies, but because sustainable alliances require equitable contributions. An America weakened by debt is ultimately a worse ally than an America that insisted on fair burden-sharing from the beginning.

The Iran Precedent

The current conflict in Iran illustrates both the necessity and the cost of American leadership. The United States and Israel acted because no other nation had the capability or the will to neutralize Iran’s nuclear program. That is a function of American strength — and it is appropriate that America led.

But the bill for that leadership is being added to a $39 trillion tab. The UK, which supported the operation in a limited defensive capacity, has been honest about its constraints. Other allies have watched from the sidelines. The Gulf states, whose security the United States has guaranteed for decades, are beneficiaries of American action without proportionate contributors to its cost.

A fiscally conservative foreign policy does not abandon allies. It prices alliance membership honestly. Nations that benefit from American security guarantees should contribute materially — in defense spending, in operational support, and in burden-sharing arrangements that reflect the actual cost of collective security.

What Sustainable American Strength Looks Like

The conservative vision for American foreign policy is not isolationism. It is prioritization. America cannot be everywhere, underwrite everything, and remain fiscally solvent. Choices must be made.

The framework should be straightforward: America leads where American interests are directly at stake, as in Iran. It supports allies who are willing to invest in their own defense. It declines to subsidize free-riders who benefit from American power without contributing to it.

This is not weakness. It is strategic discipline — the recognition that American strength in the world ultimately depends on American strength at home, including fiscal strength.

The Debt Connection

Every dollar the United States spends defending nations that could defend themselves is a dollar added to the national debt. At $7 billion in new debt per day, the math of open-ended foreign commitments is not sustainable.

None of this means cutting defense. America must remain the world’s preeminent military power — that strength is what allows it to act decisively when needed, as in Iran. But it does mean insisting that allies pay their share, that defense spending be subject to the same efficiency standards applied elsewhere in government, and that the costs of American leadership abroad be weighed honestly against the fiscal constraints at home.

Trump’s America First foreign policy, at its best, is exactly this: not retreat from the world, but a demand that America’s engagement in the world be sustainable, equitable, and anchored in clear-eyed national interest.

The $39 trillion debt is a warning. American power is not infinite. It must be husbanded wisely.
