Major Non-NATO Allies (MNNA): U.S. Security Partnerships

Major Non-NATO Allies

In an era of evolving geopolitical alliances, the United States maintains a web of strategic partnerships beyond the formal structure of NATO.

One of the most significant tools in this toolkit is the designation of Major Non-NATO Ally (MNNA) status.

This bilateral accolade, granted by the U.S. government, elevates select countries to a privileged position in defense trade, security cooperation, and military interoperability, without the binding mutual defense obligations of NATO membership.

On November 18, 2025, President Donald Trump made headlines by formally designating Saudi Arabia as the newest Major Non-NATO Ally during a high-profile White House visit by Crown Prince Mohammed bin Salman (MBS).

This move, announced at a black-tie state dinner marking 80 years of U.S.-Saudi relations, underscores a renewed push to deepen ties with key partners in critical regions.

However, what exactly does MNNA status entail, how does it differ from NATO membership, and why does Saudi Arabia’s addition matter?

Let us dive in.

What Is A Major Non-NATO Ally (MNNA)?

The MNNA designation originated in the late 1980s as part of U.S. legislation aimed at fostering closer military ties with non-NATO nations that share strategic interests with Washington.

It was first codified through amendments to the Foreign Assistance Act and Arms Export Control Act, allowing the President to confer this status after consulting Congress (typically with a 30-day notification period).

Unlike informal “ally” labels, MNNA is a formal legal status that unlocks tangible benefits:

• Expedited Arms Sales and Transfers: MNNAs gain priority access to advanced U.S. weaponry, including the ability to purchase items not readily available to other nations.
• Research and Development Cooperation: Eligibility for joint R&D projects and funding for defense technology.
• Excess Defense Articles: Priority receipt of surplus U.S. military equipment (often at reduced or no cost).
• Stockpiling and Contracting: Permission to host U.S. weapons stockpiles and allow domestic firms to bid on Pentagon repair/maintenance contracts.
• Training and Financing: Favorable terms for military training and access to certain export loans.

Importantly, MNNA status is symbolic and practical, signaling deep trust and alignment.

It does not include a mutual defense pact—there is no equivalent to NATO’s Article 5, which mandates collective defense if a member is attacked.

As of November 19, 2025, there are 20 formal MNNAs (plus Taiwan, which is treated as one under separate legislation due to sensitivities with China).

The designation has been used sparingly and strategically, often in response to regional threats or to reward partners in counterterrorism, peacekeeping, or great-power competition.

The Full List of Major Non-NATO Allies (Updated November 2025)

Here is the complete chronological list of designations:

Note: New Zealand (restored in 2002 after nuclear ban issues) and Taiwan (de facto since 2003/2019 laws) are sometimes included in broader counts.

Spotlight: Saudi Arabia’s Historic Designation

The crowning moment came on November 18, 2025, during Crown Prince Mohammed bin Salman’s visit to Washington.

At a lavish White House dinner, President Trump surprised guests by revealing:

“Tonight, I am pleased to announce that we are taking our military cooperation to even greater heights by formally designating Saudi Arabia as a major non-NATO ally, which is very important to them.”

This was not a spur-of-the-moment decision.

It capped a day of intensive talks, including the signing of a U.S.-Saudi Strategic Defense Agreement.

Key outcomes:

• Approval for Saudi Arabia to purchase F-35 stealth fighters, making it only the second Middle Eastern nation (after Israel) to acquire the advanced jet.
• Deals on civil nuclear cooperation, AI collaboration, and critical minerals supply chains.
• A pledge from Riyadh to boost U.S. investments to $1 trillion (up from $600 billion).
• Easier access for U.S. defense firms in the Kingdom and new “burden-sharing” funds to offset American costs.

For Saudi Arabia, long a de facto U.S. partner through massive arms deals (over $100 billion in the last decade), this formalizes the relationship amid regional threats from Iran-backed militias, Yemen’s Houthis, and broader Middle East instability.

It also aligns with Vision 2030 diversification efforts, allowing faster modernization of Saudi forces.

Critics, however, point to human rights concerns, including the 2018 Khashoggi murder (which Trump downplayed during the visit).

Proponents argue it strengthens deterrence against Iran and promotes stability in a volatile oil-rich region.

MNNA vs. NATO Membership: A Clear Distinction

It is easy to confuse the two, but the differences are profound:

In short, NATO is a multilateral treaty alliance for collective security. MNNA is a unilateral U.S. perk for trusted friends, powerful, but no safety net if things go south.

Why MNNA Matters In Today’s World

In a multipolar landscape dominated by China’s rise, Russian aggression, and Middle Eastern flashpoints, the U.S. cannot rely solely on NATO (focused on the Euro-Atlantic).

MNNAs fill gaps:

• Indo-Pacific Pivot: Australia, Japan, South Korea, and the Philippines form a quasi-alliance against China.
• Middle East Balancing: Israel, Egypt, Jordan, Gulf states (Bahrain, Qatar, Kuwait, now Saudi Arabia) counter Iran.
• Emerging Fronts: Kenya in Africa, Brazil/Colombia in Latin America.

Saudi Arabia’s entry solidifies a Gulf “arc” of U.S. partners, potentially easing normalization with Israel and bolstering energy security.

Looking Ahead

President Trump’s swift designation of Saudi Arabia signals an “America First” approach to alliances: pragmatic, deal-driven, and less encumbered by traditional multilateralism.

As global threats evolve, expect more such designations, perhaps for the UAE, India (long rumored), or others.

MNNA status is not a silver bullet, but it is a proven instrument for projecting U.S. influence without overcommitment.

In an uncertain world, these “major” allies outside NATO are becoming ever more vital.
