But none of these things—least of all the notion that Barack Obama, for whom initiating new wars in the Middle East is not a foreign-policy goal, will soon order the American military into action against Iran—seems, at this moment, terribly likely. What is more likely, then, is that one day next spring, the Israeli national-security adviser, Uzi Arad, and the Israeli defense minister, Ehud Barak, will simultaneously telephone their counterparts at the White House and the Pentagon, to inform them that their prime minister, Benjamin Netanyahu, has just ordered roughly one hundred F-15Es, F-16Is, F-16Cs, and other aircraft of the Israeli air force to fly east toward Iran—possibly by crossing Saudi Arabia, possibly by threading the border between Syria and Turkey, and possibly by traveling directly through Iraq’s airspace, though it is crowded with American aircraft. (It’s so crowded, in fact, that the United States Central Command, whose area of responsibility is the greater Middle East, has already asked the Pentagon what to do should Israeli aircraft invade its airspace. According to multiple sources, the answer came back: do not shoot them down.)
In these conversations, which will be fraught, the Israelis will tell their American counterparts that they are taking this drastic step because a nuclear Iran poses the gravest threat since Hitler to the physical survival of the Jewish people. The Israelis will also state that they believe they have a reasonable chance of delaying the Iranian nuclear program for at least three to five years. They will tell their American colleagues that Israel was left with no choice. They will not be asking for permission, because it will be too late to ask for permission.

When the Israelis begin to bomb the uranium-enrichment facility at Natanz, the formerly secret enrichment site at Qom, the nuclear-research center at Esfahan, and possibly even the Bushehr reactor, along with the other main sites of the Iranian nuclear program, a short while after they depart en masse from their bases across Israel—regardless of whether they succeed in destroying Iran’s centrifuges and warhead and missile plants, or whether they fail miserably to even make a dent in Iran’s nuclear program—they stand a good chance of changing the Middle East forever; of sparking lethal reprisals, and even a full-blown regional war that could lead to the deaths of thousands of Israelis and Iranians, and possibly Arabs and Americans as well; of creating a crisis for Barack Obama that will dwarf Afghanistan in significance and complexity; of rupturing relations between Jerusalem and Washington, which is Israel’s only meaningful ally; of inadvertently solidifying the somewhat tenuous rule of the mullahs in Tehran; of causing the price of oil to spike to cataclysmic highs, launching the world economy into a period of turbulence not experienced since the autumn of 2008, or possibly since the oil shock of 1973; of placing communities across the Jewish diaspora in mortal danger, by making them targets of Iranian-sponsored terror attacks, as they have been in the past, in a limited though already lethal way; and of accelerating Israel’s conversion from a once-admired refuge for a persecuted people into a leper among nations.
