Israeli leaders threaten to attack Iran's atomic weapons facilities within the next nine months before Tehran enters the "immunity zone" to then build a bomb. But it might already be too late for Israel operating alone to inflict severe damage on Iran's atomic weapons program.
Last week Israel's defense minister Ehud Barak coined the term "immunity zone" to refer to the point when Iran's atomic weapons know-how, raw materials, experience and equipment are heavily fortified in deep bunkers, immune from an Israeli attack. That means Israel must stop Iran this year before it gains atomic weapons or accept a nuclear armed enemy.
