Red lines might have averted some of the horrors of World War II, he says.
Clear red lines can work with Iran, too, he says. Red lines forced Iran to back off on its threat to close the Strait of Hormuz, he noted.
First, vital red line must be drawn “on Iran’s efforts to enrich uranium.”
He goes into the mechanics of building a bomb, and says. “For Iran, amassing enough enriched uranium is far more difficult than producing the nuclear fuse,” he says. Iran can produce “the detonator” in a year or less, in a tiny workshop that may be hard to find. “The same is true for the small facility in which they could assemble a warhead.”
So the only way to credibly stop Iran is at the enrichment stage, he says, and produces a sketch to prove his point. He explains how far along the enrichment process Iran already is.
The red line must be drawn “before Iran gets to the point where it is a few months away or a few weeks away” from amassing enough enriched uranium to make a nuclear weapon.
