The new Islamic bomb

Worried about nukes in the hands of Islamic despots? Don't look at Iran. The real problem may be Saudi Arabia. An Indian newspaper, citing the German magazine Cicero, claims that Pakistani nuclear scientists (using a pilgrimage to Mecca as a cover) have been helping the Saudis acquire nuclear know-how.

Those tempted to dismiss the report should read Joseph Trento's Prelude to Terror:

In 1975, the royal family was approached by Pakistan’s government for help in financing a pan-Islamic nuclear weapon. [Saudi Intelligence chief Kamal] Adham and his advisers had simultaneously reached the conclusion that the royal family could not survive if they let the Israeli nuclear-weapons program stand unchallenged.

So what, precisely, makes nuclear weaponry acceptable in Saudi Arabia and not in Iran?
