Mark Perry writes: While no one in the Barack Obama administration knows whether Israel will strike Iran’s nuclear program, America’s war planners are preparing for a wide array of potential Israeli military options — while also trying to limit the chances of the United States being drawn into a potentially bloody conflict in the Persian Gulf.

“U.S.-Israeli intelligence sharing on Iran has been extraordinary and unprecedented,” a senior Pentagon war planner told me. “But when it comes to actually attacking Iran, what Israel won’t tell us is what they plan to do, or how they plan to do it. It’s their most closely guarded secret.” Israel’s refusal to share its plans has persisted despite repeated requests from Defense Secretary Leon Panetta, a senior Pentagon civilian said.

The result is that, at a time of escalating public debate in both the United States and Israel around the possibility of an armed strike on Iran, high-level Pentagon war planners have had to “fly blind” in sketching out what Israel might do — and the challenges its actions will pose for the U.S. military. “What we do is a kind of reverse engineering,” the senior planner said. “We take a look at their [Israeli] assets and capabilities, put ourselves in their shoes and ask how we would act if we had what they have. So while we’re guessing, we have a pretty good idea of what they can and can’t do.”

According to several high-level U.S. military and civilian intelligence sources, U.S. Central Command and Pentagon war planners have concluded that there are at least three possible Israeli attack options, including a daring and extremely risky special operations raid on Iran’s nuclear facility at Fordow — an “Iranian Entebbe” they call it, after Israel’s 1976 commando rescue of Israeli hostages held in Uganda. In that scenario, Israeli commandos would storm the complex, which houses many of Iran’s centrifuges; remove as much enriched uranium as they found or could carry; and plant explosives to destroy the facility on their way out.
