The second fundamental pillar of the doctrine is that the addition of PMDs to the Saudi nuclear program would be carried out for purely defensive reasons. For years, the Kingdom has been the primary leader in pushing for a Weapons of Mass Destruction (WMD) Free Zone in the Middle East. It has signed the Nuclear Non-Proliferation Treaty, the Biological and Toxin Weapons Convention, and the Chemical Weapons Convention. However, the Saudis have to face the reality that all the numerous attempts to keep the Middle East free of WMDs have failed. Israel’s nuclear weapons program being the prime example of this failed policy. Therefore, if they must develop a defensive weaponized nuclear program in order to protect themselves and their allies, they will do so.
