The battlefield challenges posed by the Iranians are daunting, and a strike becomes even less appealing considering that the Iranians have not yet detonated a device and are far from a weapon. The Americans emphasize these points, but they are happy to use the Israeli threats to build pressure on the Iranians. The United States wants to undermine Iranian credibility in the region by making Iran seem vulnerable. The twin forces of Israeli rhetoric and sanctions help make Iran look embattled. The reversal in Syria enhances this sense. Naval maneuvers in the Strait of Hormuz add to the sense that the United States is prepared to neutralize Iranian counters to an Israeli airstrike, making the threat Israel poses and the weakness of Iran appear larger.
When we step back and view the picture as a whole, we see Iran using its nuclear program for political reasons but being meticulous not to make itself appear unambiguously close to success. We see the Israelis talking as if they were threatened but acting as if they were in no rush to address the supposed threat. And we see the Americans acting as if they are restraining Israel, paradoxically appearing to be Iran's protector even though they are using the Israeli threat to increase Iranian insecurity. For their part, the Russians initially supported Iran in a bid to bog down the United States in another Middle East crisis. But given Iran's reversal in Syria, the Russians are clearly reconsidering their Middle East strategy and even whether they actually have a strategy in the first place. Meanwhile, the Chinese want to continue buying Iranian oil unnoticed.
It is the U.S.-Israeli byplay that is most fascinating. On the surface, Israel is driving U.S. policy. On closer examination, the reverse is true. Israel has bluffed an attack for years and never acted. Perhaps now it will act, but the risks of failure are substantial. If Israel really wants to act, this is not obvious. Speeches by politicians do not constitute clear guidelines. If the Israelis want to get the United States to participate in the attack, rhetoric won't work. Washington wants to proceed by increasing pressure to isolate Iran. Simply getting rid of a nuclear program not clearly intended to produce a device is not U.S. policy. Containing Iran without being drawn into a war is. To this end, Israeli rhetoric is useful.
Rather than seeing Netanyahu as trying the force the United States into an attack, it is more useful to see Netanyahu's rhetoric as valuable to U.S. strategy. Israel and the United States remain geopolitically aligned. Israel's bellicosity is not meant to signal an imminent attack, but to support the U.S. agenda of isolating and maintaining pressure on Iran. That would indicate more speeches from Netanyahu and greater fear of war. But speeches and emotions aside, intensifying psychological pressure on Iran is more likely than war.
