David Albright, who worked for the IAEA in the 1990s, says he believes breakout time is zero but it’s still unclear how long it would take for Tehran to build a nuclear weapon.

Both American and Israeli officials have assessed that Iran now needs only a few weeks to amass enough fissile material for a bomb, should it choose to make one, though it will need additional time to assemble the device’s other components.
