What is the US-Saudi Arabia nuclear deal and why is it causing concern?

The US and Saudi Arabia have signed a landmark peaceful nuclear cooperation agreement and bilateral safeguards agreement to establish a civilian nuclear programme. Using American technology and expertise, the deal is supported by the Trump administration. However, it has caused alarm in Washington and the Middle East. Critics fear the agreement could allow Saudi Arabia to enrich uranium domestically, potentially sparking a regional arms race and increasing nuclear proliferation risks within the Middle East.
