This bill directs the President to give formal notice of denunciation of the North Atlantic Treaty within 30 days of enactment, initiating U.S. withdrawal proceedings under Article 13 of the Washington Treaty. It also bars the use of any funds made available by statute to pay U.S. contributions to NATO’s common-funded budgets — the civil budget, military budget, and the Security Investment Program — and contains a severability clause.
Beyond the immediate procedural command to the executive, the bill asserts congressional authorization for withdrawal by citing and satisfying section 1250A of the FY2024 NDAA. If implemented, the measure would remove U.S. participation in NATO’s pooled budgets, change how the United States legally approaches treaty exit, and create a cascade of operational, budgetary, and diplomatic effects for U.S. forces and allied planning that go well beyond the line-item funding cut.
At a Glance
What It Does
The bill requires the President to give notice of denunciation of the North Atlantic Treaty within 30 days of enactment and thereby commence withdrawal under Article 13; it also prohibits use of any funds made available by statute to finance U.S. contributions to NATO’s common budgets. It declares that passage satisfies the congressional-authorization requirement in section 1250A of the FY2024 NDAA.
Who It Affects
The measure directly affects the Executive Branch (State Department and Department of Defense), appropriations authorities, and NATO’s institutional budgets. It also changes the legal footing for U.S. treaty status for NATO and therefore impacts allied governments, defense contractors tied to NATO programs, and planners in European capitals.
Why It Matters
This is a statutory attempt to compel a unilateral treaty exit and to cut off institutional alliance funding simultaneously — a combination that would reshape U.S. obligations without specifying operational redeployment. For lawyers, budget officers and policy teams, it creates immediate compliance, appropriation, and treaty-timing questions that agencies must resolve rapidly.

What This Bill Actually Does
The bill gives Congress’s clear instruction: the President must send notice to denounce the North Atlantic Treaty within 30 days of enactment. The statute points to Article 13 of the Washington Treaty as the legal mechanism for withdrawal; Article 13 authorizes denunciation by a Party and, under its terms, a notice typically produces withdrawal after a statutory waiting period set by the treaty.
The bill does not re-write Article 13; it triggers the treaty’s existing exit procedure.
Alongside the denunciation command, the bill bars the use of any funds that Congress authorizes or appropriates to pay United States contributions to NATO’s common-funded budgets — explicitly naming the civil budget, military budget, and the Security Investment Program. That prohibition is broad: it sweeps in funds “authorized to be appropriated, appropriated, or otherwise made available by any Act,” which raises immediate questions for departments that currently obligate multiyear contributions or that transfer funds for alliance programs.The text also handles an internal legal requirement: it states that passage satisfies section 1250A of the FY2024 National Defense Authorization Act, the statutory provision Congress created to require congressional authorization before suspension, termination, denunciation, or withdrawal from the North Atlantic Treaty.
Finally, the bill includes a standard severability clause to preserve the remainder of the act if any part is struck down.Practically, the statute compels a legal withdrawal process and simultaneously cuts off centralized NATO funding streams. It does not itself order immediate redeployment of U.S. forces, amend Status of Forces Agreements, or amend other statutes that authorize personnel, basing, or bilateral support; those downstream actions would require separate steps by the President, the Defense Department, and appropriators.
The combined effect — notice plus a funding ban — is designed to force a rapid severance of the United States’ institutional ties to NATO while leaving many implementation details to agencies and future legislation.
The Five Things You Need to Know
The bill requires the President to give notice of denunciation of the North Atlantic Treaty not later than 30 days after enactment.
It invokes Article 13 of the Washington Treaty as the withdrawal mechanism; under Article 13, denunciation triggers the treaty’s prescribed notice period before a Party ceases being a member.
Section 5 prohibits use of any funds “authorized to be appropriated, appropriated, or otherwise made available by any Act” to pay U.S. contributions to NATO’s civil budget, military budget, and Security Investment Program.
Section 4 states the Act satisfies the congressional-authorization requirement in section 1250A of the FY2024 NDAA for withdrawal from the treaty.
Section 6 contains a severability clause so that if a court voids part of the Act, the remaining provisions are intended to remain in force.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act’s popular names: the “Not A Trusted Organization Act” and the “NATO Act.” This is purely stylistic but matters for references in legislative and policy work.
Findings
Lists 18 findings that frame the authors’ policy case: NATO’s post‑Cold War expansion, U.S. financial dominance of the alliance, alleged broken assurances about eastward expansion, and the assertion that NATO membership is inconsistent with U.S. national security interests. These findings are nonbinding policy rhetoric but they animate statutory choices and will be cited in administrative and judicial contexts to justify agency implementation choices.
Mandatory denunciation under Article 13
Directs the President to give notice of denunciation of the North Atlantic Treaty not later than 30 days after enactment. The provision compels the executive to use the treaty’s existing exit route rather than inventing a novel withdrawal mechanism. Agencies will need to reconcile this statutory command with their treaty‑exit procedures and the operational realities of force posture, logistics, and alliance consultation.
Satisfies NDAA §1250A congressional-authorization requirement
States that the Act fulfills the statutory prerequisite Congress added in the FY2024 NDAA that congressional authorization accompany any suspension, termination, denunciation, or withdrawal from the North Atlantic Treaty. Practically, this is Congress authorizing the action by statute rather than leaving a pure executive withdrawal; it alters the usual separation of powers dynamic by attaching a congressional imprimatur to the withdrawal.
Broad prohibition on funding NATO common budgets
Bars any funds authorized or appropriated by any Act from being used to pay U.S. contributions to NATO’s common-funded budgets, naming the civil budget, military budget, and Security Investment Program. The breadth of the funding ban (covering any statutory funding source) creates immediate accounting and contracting issues: agencies must determine which obligations, existing multi-year commitments, or intergovernmental transfers fall within the ban and what statutory exceptions, if any, might apply.
Severability
Standard provision preserving the remainder of the Act if a court invalidates any portion. Given likely legal challenges around separation of powers and appropriations, the severability clause signals Congressional intent to preserve as much of the statute as possible if a court faults one part.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Budget hawks and reprioritization advocates — the funding prohibition and withdrawal start a legal pathway to reduce or reallocate U.S. expenditures tied to NATO’s pooled budgets, which these stakeholders can repurpose domestically or for other priorities.
- Policymakers and constituencies favoring unilateral strategic autonomy — removing treaty obligations restores executive discretion (after denunciation) to act without alliance constraints and may be seen as enabling a different global posture.
- Some European states and defense planners who favor accelerated European burden‑sharing — the U.S. exit and the accompanying funding cut could pressure EU and NATO partners to invest more in collective capabilities and indigenous defense industrial base, aligning with those who seek faster European defense integration.
Who Bears the Cost
- Department of Defense and Department of State — they must implement the notice, unwind or reprogram obligations, and absorb operational and contractual disruptions; budget offices will face complex reclassification and legal risk in stopping funds.
- NATO’s institutional structures and member-states — pooled programs financed by the common budgets would face immediate shortfalls, delaying or canceling projects financed through the civil, military, or Security Investment Program budgets.
- Allied militaries and defense contractors — many procurement projects and cooperative programs that depend on common funding will see gaps; companies participating in multinational infrastructure or capability projects face lost contracts and demand shocks.
- U.S. diplomatic posture and credibility — allies that rely on U.S. treaty commitments bear the strategic and political cost of a sudden legal severing of alliance guarantees, complicating crisis management and deterrence planning.
Key Issues
The Core Tension
The bill pits two legitimate objectives against one another: the desire to reclaim unilateral control over U.S. foreign policy and defense spending versus the strategic value of binding, predictable alliance commitments. Forcing a rapid treaty exit and cutting institutional funding can deliver immediate fiscal and autonomy gains, but it simultaneously risks degrading collective deterrence, creating legal disputes over obligations, and handing strategic advantage to competitors — a tradeoff with no clean operational or legal solution.
The bill creates several sharp implementation and legal questions. Compelling the President to give notice of denunciation within a set window is legally unusual: treaty withdrawal has traditionally been treated as an executive power, and Congress’s statutory direction to act raises separation‑of‑powers issues that courts could have to resolve.
In parallel, the funding ban’s breadth — covering funds “authorized to be appropriated, appropriated, or otherwise made available by any Act” — sweeps across current and future appropriations, but it does not itself address existing intergovernmental or contractual commitments that were obligated before enactment. Agencies will need to decide whether they can legally stop payments without breaching contracts or statutory obligations, and courts may be asked to adjudicate those disputes.
Strategically, the statute forces a mismatch between legal posture and on‑the‑ground operations. Denunciation under Article 13 typically becomes effective only after the treaty’s notice period elapses, which can create a phase during which the United States is legally still a Party but statutorily prohibited from funding core alliance institutions.
That mismatch risks creating capability gaps (maintenance, procurement, infrastructure projects) and undermines planning signals to allies and adversaries. Finally, the bill does not address downstream legal instruments — Status of Forces Agreements, basing arrangements, or NATO operational frameworks — leaving a host of necessary legislative and diplomatic follow‑ons unaddressed.
