US–Saudi Arabia Nuclear Cooperation Another Threat to the Nuclear Non-Proliferation RegimeOn 22 July 2026, the US administration announced a nuclear deal with Saudi Arabia. The Basis of the Nuclear Non-Proliferation RegimeThe nuclear non-proliferation regime is based on the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The US-Saudi nuclear cooperation might trigger the next step of escalation and could severely damage the international non-proliferation regime, as further explained below. Why the US-Saudi Deal MattersOn the first sight, the US-Saudi nuclear cooperation is a cooperation for a civilian nuclear programme. This is even more worrisome given statements by Saudi Arabia’s Crown Prince, that once Iran has nuclear weapons, Saudi Arabia would follow suit.
