MNNA status was first created in 1987, when
Congress added section 2350a — otherwise known as the
Sam Nunn Amendment — to
Title 10 of the United States Code. It stipulated that cooperative research and development agreements could be enacted with non-NATO allies by the
secretary of defense with the concurrence of the
secretary of state. The initial MNNAs were
Australia,
Egypt,
Israel,
Japan, and
South Korea. When enacted, the statute designated the initial five countries as major non-NATO allies and added
New Zealand to the list.
New Zealand U.S.–New Zealand strategic and military cooperation suffered a setback after the breakdown of the
ANZUS Treaty in 1984, triggered by disagreements over
nuclear ship entry. The designation of New Zealand as an MNNA in 1996 reflected the warming of bilateral relations between the two countries. In June 2012, New Zealand signed a partnership arrangement with the
North Atlantic Treaty Organization (NATO), further strengthening and consolidating relations with the United States.
Argentina In 1998, President
Bill Clinton named
Argentina as an MNNA for the "Argentine compromise and contribution to international peace and security" that was materialized in its participation in the
Gulf War (Argentina was the only South American country to join the coalition's fight against
Iraq), and for its continuing support for
United Nations peacekeeping missions.
Taiwan When Congress enacted the Foreign Relations Authorization Act for FY 2003 on September 30, 2002, it required that
Taiwan be "treated as though it were designated a major non-NATO ally". Despite some initial misgivings about Congress's perceived intrusion into the President's foreign affairs authority, the
Bush administration subsequently submitted a letter to Congress on August 29, 2003, designating
Taiwan as a
de facto MNNA. However, in October 2003, President George W. Bush and his Singaporean counterpart
Goh Chok Tong announced their intention to conclude a major bilateral Strategic Framework Agreement for a Closer Cooperation Partnership in Defence and Security (SFA), the details of which remained secret; it was signed on July 12, 2005.
Pakistan The designation of certain countries as MNNAs has not been without controversy, as has been the case with
Pakistan, which was designated as an MNNA by President
George W. Bush in 2004. In 2017,
Ted Poe (
R–
TX) and
Rick Nolan (
D–
MN) from the
House of Representatives introduced H.R. 3000; a bill to revoke Pakistan's position as an MNNA, citing
inadequate counterterrorism efforts, the
harboring of Osama bin Laden, and consistent Pakistani support for the
Taliban. The bill never received a vote, but in 2021, U.S. Representative
Andy Biggs introduced H.R. 35 — another version of the legislation. In 2017,
Joseph Dunford, erstwhile chairman of the
Joint Chiefs of Staff, accused Pakistan's
Inter-Services Intelligence of having ties to terrorist groups.
Reuters reported that "possible
Trump administration responses being discussed include expanding
U.S. drone strikes and perhaps eventually downgrading Pakistan's status as a major non-NATO ally." In January 2023, Biggs introduced a bill to remove Pakistan's MNNA status.
Tunisia In May 2015, President
Barack Obama declared his intention to designate
Tunisia as an MNNA while hosting his Tunisian counterpart
Beji Caid Essebsi at the
White House.
Brazil In 2019, President
Donald Trump designated
Brazil as an MNNA for "Brazil's recent commitments to increase defense cooperation with the United States" after receiving a working visit from his Brazilian counterpart
Jair Bolsonaro. base is home to

Abdel Fattah el-Sisi during a meeting held at

Qatar On January 31, 2022, President Joe Biden announced that
Qatar would be designated as an MNNA, citing its assistance during the
United States' withdrawal from Afghanistan in 2021. "This past year, our partnership with Qatar has been central to many of our most vital interests", Biden commented. "I'm notifying Congress that I will designate Qatar as a major non-NATO ally to reflect the importance of our relationship; I think it's long overdue". This relationship serves as a major upgrade for the relations between the U.S. and Qatar. It is the third country in the Gulf region to become a major non-NATO ally after Bahrain and Kuwait. On September 29, 2025, President Donald Trump signed an executive order guaranteeing U.S. support for the defense of Qatar if it receives an "armed attack," promising a U.S. military response to such aggression. The order represents a commitment by Trump and his administration and is not a legally-binding treaty, which would have to be approved by at least two-thirds of the Senate in order for the president to ratify it.
Colombia In March 2022, President
Joe Biden designated
Colombia as an MNNA, stating: "I've said for a long time Colombia is a keystone to our shared efforts to build a hemisphere as prosperous, secure and democratic ... Today I'm proud to announce that I intend to designate Colombia a major non-NATO ally because that's exactly what you are. A major, Major non-NATO ally."
Kenya On May 23, 2024, President Joe Biden announced that
Kenya would be the 20th nation granted MNNA status, in recognition of its willingness to lead an
intervention in Haiti, which went into effect a month later on June 24.
Saudi Arabia Following his meeting with Crown Prince
Mohammed bin Salman, President Donald Trump announced on November 18, 2025 that
Saudi Arabia would be designated as an MNNA. Trump also stated he and Salman signed an "historic strategic defense agreement". The designation, aimed at expanding bilateral military cooperation, accompanied
Riyadh's pledge to increase its planned U.S. investments from USD$600 billion to $1 trillion and Trump's confirmation that the U.S. will sell
F-35 fighter jets to the kingdom, making it the first
Middle Eastern state outside Israel to obtain the aircraft. Trump, noting the U.S. already counts 19 major non-NATO allies, said the strengthened partnership would advance shared security interests, while also remarking controversially on the 2018 killing of journalist
Jamal Khashoggi. The White House added that Saudi Arabia intends to purchase nearly 300 U.S. tanks. ==Potential MNNAs==
