i don't see why saudi arabia shouldn't have a nuke, they have enormous quantities of cash, a very secretive state and society and a close political and military relationship with a state that sells nuclear weapons technology.
they also have a real fear of iran and israel (being rich doesn't stop them being stupid) and the lifeblood that keeps the country a viable proposition is running out.
if iraq becomes a successful, independent country with a US presence and outward-looking government then saudi arabia will lose all US and western support.
then they will be in very deep poo. and they know it.
what better recipe for nuclear proliferation could there be: a rich, scared elite with very little public and international support that knows things are going to get worse.
just because it comes from iran doesn't invalidate it, they wear two-legged trousers, should americans wear three-legged trousers out of spite?
No! Ya think?
