Netanyahu: "Those Who Refuse to Put Red Lines before Iran Don't Have a Moral Right to Place a Red Light before Israel"
Prime Minister Benjamin Netanyahu said Tuesday that if world powers refused to set a red line for Tehran's nuclear program, they could not demand that Israel hold its fire. "The world tells Israel 'wait, there's still time.' And I say, 'Wait for what? Wait until when?' Those in the international community who refuse to put red lines before Iran don't have a moral right to place a red light before Israel," he said. "Now if Iran knows that there is no red line, if Iran knows that there is no deadline, what will it do? Exactly what it's doing. It's continuing, without any interference, towards obtaining nuclear weapons capability and from there, nuclear bombs."
