More evidence that Saudi Arabia will not sit idly by if Iran goes nuclear, which means more evidence that the Middle East could be looking at a terrible nightmare, a nuclear arms race in the world's most volatile region, which means that the chance for escalation to accidental nuclear war (which I wrote about here) would eventually be quite high:

A senior Saudi Arabian diplomat and member of the ruling royal family has raised the spectre of nuclear conflict in the Middle East if Iran comes close to developing a nuclear weapon.

Prince Turki al-Faisal, a former Saudi intelligence chief and ambassador to Washington, warned senior Nato military officials that the existence of such a device "would compel Saudi Arabia ... to pursue policies which could lead to untold and possibly dramatic consequences".

He did not state explicitly what these policies would be, but a senior official in Riyadh who is close to the prince said yesterday his message was clear.

"We cannot live in a situation where Iran has nuclear weapons and we don't. It's as simple as that," the official said. "If Iran develops a nuclear weapon, that will be unacceptable to us and we will have to follow suit."

Walter Russell Mead notes that Saudi Arabia's pronounced interest in keeping Iran from going nuclear suggests that maybe, just maybe, this isn't only about The Jooz.
