 At least a year away from having the breakout capacity of producing fissile material for a nuclear weapon is now probably one or two weeks away from doing that. Now, they haven't developed the weapon itself. One or two weeks. One or two weeks is probably what the realistic breakout time is. They haven't produced a weapon itself, but that's something, of course, that we track very, very carefully. And you put those two things together, the fissile material, an explosive device, and you have a nuclear weapon.
