U.S. Assures Israel That Iran Threat Is Not Imminent

Administration officials said they believe the assessment has dimmed the prospect that Israel would pre-emptively strike against the country’s nuclear facilities within the next year, as Israeli officials have suggested in thinly veiled threats.

For years, Israeli and American officials have debated whether Iran is on an inexorable drive toward a nuclear bomb and, if so, how long it would take to produce one. A critical question has been the time it would take Tehran to convert existing stocks of low-enriched uranium into weapons-grade material, a process commonly known as “breakout.”

Israeli intelligence officials had argued that Iran could complete such a race for the bomb in months, while American intelligence agencies have come to believe in the past year that the timeline is longer.

“We think that they have roughly a year dash time,” said Gary Samore, President Obama’s top adviser on nuclear issues, referring to how long it would take the Iranians to convert nuclear material into a working weapon. “A year is a very long period of time.”
