WASHINGTON (AP) – Defending an emerging nuclear deal, President Barack Obama said Iran would be kept a year away from obtaining a nuclear weapon for more than a decade, but conceded Tuesday that the buffer period could shrink to almost nothing after 13 or more years.
Obama, whose top priority at the moment is to sell the framework deal to critics, was pushing back on the charge that the deal fails to eliminate the risk because it allows Iran to keep enriching uranium. He told NPR News that Iran will be capped for a decade at 300 kilograms – not enough to convert to a stockpile of weapons-grade material.
“What is a more relevant fear would be that in Year 13, 14, 15, they have advanced centrifuges that enrich uranium fairly rapidly, and at that point, the breakout times would have shrunk almost down to zero,” Obama said.
Breakout time refers to how long it would take to build a bomb if Iran decided to pursue one full-bore – in other words, how long the rest of the world would have to stop it. The framework deal expands Iran’s breakout time – currently two to three months – to at least a year. But that constraint would stay in place only for 10 years, at which point some restrictions would start phasing out.
Although Obama acknowledged that Iran’s breakout time could shrink, he said at least the world would have better insight into Iran’s capabilities because of extensive inspections in the earlier years.
