The report that Saudi Arabia has agreed to let Israeli jets transit its airspace to attack Iran’s nuclear facilities indeed shows, as Jennifer noted, that progress in the “peace process” is not necessary to secure Israeli-Arab cooperation on a grave mutual threat. But it also constitutes a vote of no-confidence — by both Saudi Arabia and at least someone in the U.S. administration — in the anti-Iran sanctions that the UN Security Council approved last week.

At a time when the Muslim world is still seething over Israel’s botched raid on a Gaza-bound flotilla, nothing could be more embarrassing for Saudi Arabia than a report that it is cooperating with the hated Zionist entity in planning an attack on another Muslim country. Under these circumstances, only one thing could motivate a Saudi official to actually confirm this cooperation to the London Times: sheer terror.

And the report’s timing — just days after U.S. President Barack Obama proclaimed the new round of toothless sanctions a great achievement, even as he openly acknowledged that they will not stop Iran’s nuclear program — makes the source of this terror clear: Saudi Arabia is now convinced that the West, in general, and Americans, in particular, will do nothing substantive to stop Iran’s nuclear program. Saudi Arabia has thus concluded that the only hope of making Tehran rethink the program’s wisdom is a credible threat of force. By agreeing to let Israeli jets transit its airspace, thus shortening the distance they would have to fly, Riyadh has greatly increased the credibility of this threat by making an Israeli strike more feasible.

The same logic applies to the U.S. The Obama administration has repeatedly and publicly trumpeted its efforts to thwart an Israeli strike; indeed, the Times reported that Washington still refuses to let Israeli jets transit Iraqi airspace, which the U.S. controls. Moreover, Obama continues to invest great efforts in outreach to the Muslim world. That a U.S. “defense source” confirmed this story to the Times and even asserted that the deal was concocted “with the agreement of the [U.S.] State Department” is deeply embarrassing to the administration, depicting it as downright hypocritical: publicly voicing full-throated opposition to an Israeli raid even as it secretly brokers a deal with Riyadh to facilitate such a raid.

And here, too, the motive is clear: at least someone in the administration has concluded that truly painful sanctions — the kind that might actually affect Tehran’s behavior — are never going to be enacted, so the only hope is a credible threat of military force.

It is, of course, encouraging to learn that both Riyadh and at least some parts of Washington still have a grasp of reality. Yet given the almost unanimous agreement among Western leaders that a military strike on Iran would be disastrous, it is deeply discouraging that they nevertheless remain incapable of mustering the will to enact the kind of sanctions that are the only alternative to such a strike — other than a nuclear Iran.
