“U.S. Assures Israel That Iran Threat Is Not Imminent” was the headline in the New York Times last Thursday. The article reported that U.S. officials were telling Jerusalem not to worry. It “would take roughly a year — and perhaps longer — for Iran to complete what one senior official called a ‘dash’ for a nuclear weapon.”

Let’s assume for a moment that that the administration’s estimate is correct, even though our intelligence assessments of the Iranian nuclear program—and nuclear matters generally—have been notoriously problem riddled. Iran has been pursuing a nuclear capability for decades; if only a year remains in the effort, it is already in the “dash.”
