Saudi Arabia wants nukes if Iran develops them

The Guardian reports:

The US and Saudi Arabia have agreed a landmark deal that would use American technology and expertise to establish a civilian nuclear program in the Gulf country, a move that has caused alarm across the Middle East and through the corridors of power in Washington.

Much of the deal remains unclear, but concerns centre on whether Saudi Arabia would have the capability to enrich uranium domestically, and what that means for nuclear proliferation.

They claim it is for nuclear power, but if that was the case there would be no need for domestic enrichment. You only want domestic enrichment if you want to be able to ensure you can go up to the level needed for weapons.

Now if Iran develops a nuclear weapon, there is a case to be made that Saudi Arabia should be able to develop them also, as they can hold each other in check. But it would be better if neither of them have any domestic enrichment capability.
