"A unilateral attack from Israel . . . would be a grave mistake for all the reasons made plain by Meir Dagan and so many others. It is terrible enough to imagine what might happen if Iran came to possess a bomb; but an attack now would almost certainly lead to a tide of blood in the region. The Middle East today is in a state of fragile possibility, full of peril, to be sure, but also pregnant with promise. A premature unilateral attack could upend everything and one result of many would be an Israel under fire, under attack, and more deeply isolated than ever before."
