U.S.–Saudi Arabia Alliance Reinforced as Riyadh Gains Major-Non-NATO Ally Status and $1 Trillion Investment Pledge
Crown Prince’s US visit culminates in sweeping defence, energy and technology deals, deepening strategic partnership under President Trump
The United States and Saudi Arabia marked a new chapter in their decades-long alliance following the White House meeting between U.S. President Donald J. Trump and Saudi Crown Prince Mohammed bin Salman on November 18, 2025. Washington formally designated Riyadh a “major non-NATO ally,” while the Kingdom pledged to raise its U.S. investment commitments to nearly one trillion dollars — reinforcing both economic and security ties.
The summit produced a broad set of agreements spanning defence, civil nuclear cooperation, energy, technology and investment.
The two governments finalised a Strategic Defense Agreement, paving the way for expanded military cooperation.
In parallel, a civil nuclear energy pact will position American firms as Saudi Arabia’s partners of choice for decades-long cooperation under strict non-proliferation safeguards.
Economically, Riyadh committed to invest almost one trillion dollars in the U.S., building on earlier pledges made in May 2025. The agreements aim to boost American exports, create high-paying jobs and strengthen supply chains in critical sectors such as energy, artificial intelligence, defense manufacturing and advanced technology.
For Washington, the deals reinforce U.S. leadership in global technology, energy and industrial value chains while securing long-term strategic cooperation with a key Middle East partner.
The elevation of Saudi Arabia’s status to a major non-NATO ally — a privileged designation shared by only a small group of U.S. partners — grants Riyadh easier access to U.S. weaponry, enhanced military collaboration and eligibility for defense contracts, thereby strengthening regional deterrence.
The two governments also emphasised mutual efforts to promote regional stability and counter shared security threats.
Analysts describe the visit as potentially transformative.
While the fundamentals of the U.S.–Saudi relationship — energy, security, and regional geopolitics — remain, the pair are explicitly broadening cooperation to include advanced technology, civil infrastructure and economic diversification.
The success of this expanded agenda will depend on sustained follow-through.
Observers note that the deals could reshape not only Gulf-US relations, but also regional dynamics in energy, defense, and technology supply chains.
For President Trump, the reinforced alliance underscores a strategic vision that views Saudi Arabia as a core partner in U.S. Middle-East policy, combining economic leverage with security cooperation.
As the agreements begin to be implemented, both nations appear committed to building a durable, multifaceted partnership poised to influence global markets and geopolitics for years to come.
