Israel Running Out of Time to Stop Iran

Word is the Russians are about to help Iran load nuclear fuel in their plutonium plant.  Things get pretty complicated after that:

News that Russia will load nuclear fuel rods into an Iranian reactor has touched off a countdown to a point of no return, a deadline by which Israel would have to launch an attack on Iran's Bushehr reactor before it becomes effectively "immune" to any assault, says former Bush administration U.N. Ambassador John R. Bolton.

Once the fuel rods are loaded, Bolton told Fox News on Friday afternoon, "it makes it essentially immune from attack by Israel. Because once the rods are in the reactor an attack on the reactor risks spreading radiation in the air, and perhaps into the water of the Persian Gulf."

Russian Prime Minister Vladimir Putin declared in March that Russia would start the Bushehr reactor this summer. But the announcement from a spokesman for Russia's state atomic agency to Reuters Friday sent international diplomats scrambling to head off a crisis.

The story immediately became front-page news in Israel, which has laid precise plans to carry out an attack on Iran's nuclear facilities while going along with President Obama's plans to use international sanctions and diplomatic persuasion to convince Iran's clerics not to go nuclear.

Bolton made it clear that it is widely assumed that any Israeli attack on the Bushehr reactor must take place before the reactor is loaded with fuel rods.

"If they're going to do it that's the window that they have," Bolton declared. "Otherwise as I said before, once the rods are in the reactor, if you attack the reactor you're going to open it up and radiation will escape at least into the atmosphere and possibly into the waters of the Persian Gulf.

"So most people think that neither Israel nor the United States, come to that, would attack the reactor after it's been fueled."

The real question is if the Israelis want to make an attack they'll have to cross through airspace controlled by the U.S. The Saudis have already more or less given permission to use their airspace, but I don't know what discussions have been held with U.S. officials regarding overflying Iraq.

Would U.S. forces actually attempt to stop an Israeli attack?  If directly ordered by the White House, they would.  Would Obama give such an order?  We might be about to find out.
