Netanyahu, like every previous Israeli prime minister, understands that an Israeli strike against Iran depends not only on US tolerance, but direct involvement against Iran, at least after the initial attack. In May 2008, his predecessor, Ehud Olmert, had requested the approval of George W Bush for an air attack on Iran, only to be refused by Bush.
Netanyahu apparently feels, however, that he can manipulate right-wing Israeli influence on American politics to make it impossible for Obama to stay out of an Israeli war on Iran. He has defied the Obama administration by refusing to assure Washington that he would consult them before making any decision on war with Iran.
The Obama administration's warning signal on the danger of an Israeli attack began flashing red after Secretary of Defence Leon Panetta came back empty-handed from a trip to Israel in September.
US officials then came up with a new strategy for pulling Israel back from the precipice of war by letting Netanyahu know that, if the US were denied a full role in coordinating military policy toward Iran, it would not come to Israel's aid in such a war.
The first step in the strategy came when Panetta was answering
questions after a talk at the Saban Centre of Brookings Institution on
December 2. He not only expressed clear disapproval
of an Israeli attack as counter-productive -- something the
administration had avoided in 2009 and 2010 -- but went on to indicate
that the US was concerned that it "could possibly be the target of
retaliation from Iran, striking our ships, striking our military
bases."
Initial hint by the US
Without saying so directly, that remark hinted that the US would take steps to avoid that situation, if necessary. It was evidently aimed at planting the seed of doubt in Netanyahu's mind that Obama would be willing to respond to Iranian retaliation against Israel in the event of an Israeli strike.
The next move came five weeks later, when Panetta, on CBS news "Face the Nation", made the initial hint even clearer. Panetta was then asked what the US would do if Israel were to strike Iran, despite the refusal to consult the US in advance. Panetta said, "If the Israelis made that decision, we would have to be prepared to protect our forces in that situation. And that's what we'd be concerned about."
The Israelis could easily discern that Panetta really saying the US would not retaliate against Iran unless its own bases or ships in the region were hit by Iran. Given Panetta's statement a month earlier suggesting concern that Iran might retaliate against US forces, that answer could also be regarded as a signal to Iran that the US was prepared to decouple from an Israeli war with Iran.
Although publicly there was studied silence from Jerusalem, that Panetta hint elicited a formal diplomatic protest from Israeli Ambassador Michael Oren. And Israel still showed no sign of softening its defiant policy of unilateralism on Iran.
Then Obama approved an explicit expression of the same message to the Israelis. According to the account circulating among senior officers close to the Joint Chiefs, on January 20 the Chairman of the Joint Chiefs of Staff, Gen. Martin Dempsey, told Netanyahu and Defence Minister Ehud Barak that the US would not defend Israel if it launched an attack on Iran that had not been coordinated with the US.
But Netanyahu had already put into effect his own counter-strategy, which is to use the influence of the Israeli lobby in Congress to help the Republicans against Obama in the presidential election and to maximize the pressure on Obama to support an Israeli attack on Iran.
Last December, Netanyahu's supporters in the US lobbied the US Congress to pass economic sanctions against Iran focused squarely on Iran's crude oil exports and Central Bank. The Obama administration strongly opposed the legislation. Obama's Treasury Secretary Timothy Geithner wrote a letter to the Senate warning that the proposed sanctions would cause a spike in world oil prices, thus risking further deterioration of the global economy. In the end, the Obama administration was forced by Congressional action to adopt the sanctions.
But the sanctions on Iran's crude oil sector would only go into effect six months later, as would the EU cut-off of its imports of Iranian oil adopted in January. So the Obama administration had a six-month window for negotiations with Iran on its nuclear program.
How could it maximize the pressure on the Iranians to reach an agreement within six months? The obvious answer was to bring back an old theme in Obama policy -- using the threat of an Israeli attack to gain diplomatic leverage on Tehran. In order to maximize that leverage, the Obama administration sought to portray Israel as poised to attack some time between April and end of June.
