by Roula Khalaf, Financial Times, UK - Surely a more useful attempt at dialogue should involve Iran, Hizbollah’s chief backer. Both Saudi Arabia and Iran have an interest in containing a Sunni-Shia conflict of the vicious kind that has blighted Iraq – and that is what Lebanon’s violence is bound to develop into unless rapidly checked. Saudi Arabia can ill-afford to have its Sunni allies routed by a Shia group and could, eventually, be forced to intervene militarily. But Iran too has much to lose from a Lebanese civil war, not least Hizbollah’s aura of mighty resistance movement confronting Israel.
