In a major development during his diplomatic visit, US President Donald Trump oversaw the signing of a massive $142 billion US Saudi Arabia defence deal in Riyadh on Tuesday. The agreement, described by the White House as a “milestone in US-Saudi relations,” includes the transfer of advanced weapons systems, military services, and other commercial agreements between American firms and the Saudi government.
This deal not only reaffirms America’s strategic alignment with Saudi Arabia but also opens new doors for economic and defence cooperation, including technology exports and energy solutions.
What’s Included in the $142 Billion Deal?
According to an official White House factsheet, the US Saudi Arabia defence deal includes:
- Advanced arms sales and weapons systems
- Military training and logistics support

Additionally, the broader package includes commercial trade agreements, such as:
- $14.2 billion worth of gas turbines and energy solutions from General Electric

This multi-sectoral approach reflects a comprehensive investment framework, extending beyond traditional defence pacts.

Trump’s Statement on the Agreement
During the signing ceremony held at the Royal Palace in Riyadh, President Trump hailed the pact as a “historic step toward greater cooperation”.
“This agreement strengthens not only our military bond but also our economic and strategic partnership. We are proud to stand with Saudi Arabia as we both seek peace, stability, and prosperity in the region,” Trump said.
He also praised Crown Prince Mohammed bin Salman for his commitment to economic reform and closer cooperation with Western allies.
Part of a $600 Billion Saudi Investment Promise
The defence agreement is only one component of a larger $600 billion investment package announced by Saudi Arabia. The rest of the investments span:
- Energy infrastructure
- Technology and communications
- Health care and education sectors
- Green energy development
This is part of the Crown Prince’s Vision 2030 strategy, aiming to diversify the Saudi economy away from oil and position the kingdom as a high-tech industrial power.
Geopolitical Significance of the Deal
The US Saudi Arabia defence deal comes at a time of shifting alliances and growing uncertainty in the Middle East.
Strategic Implications:
- Sends a strong message to Iran amid rising nuclear tensions
- Reinforces US military presence in the Gulf region
- Counters the increasing footprint of China and Russia in the Middle East
- Builds Saudi capability to handle regional conflicts independently
Criticism and Concerns
While the deal has been lauded for its strategic depth, it also drew criticism from human rights groups and lawmakers, especially in the US.
Key concerns:
- Use of US-supplied arms in civilian conflict zones like Yemen
- Potential for fueling regional arms races
- Absence of human rights clauses in the agreements
Despite these, the Trump administration has maintained that strategic alliances must take precedence over domestic politics in moments of global recalibration.
US-Saudi Relations: A New Chapter
This deal signals a renewed chapter in US-Saudi relations, particularly under Trump’s administration, which has prioritized economic diplomacy and defence exports as key foreign policy tools.
Unlike previous administrations that emphasized conditionality and reform, Trump’s approach has focused on transactional alignment and regional balance of power.
