THE UNIMAGINABLE but ultimately inescapable truth is that we are going to have to get ready for war with Iran. \n\nWhile we were chasing phantom nuclear weapons in Mesopotamia, next door Iran was busy building real ones. \n\nThe unavoidable reality is that we now need urgently to steel ourselves to the ugly probability that diplomacy will not now suffice: one or way or another, unconscionable acts of war may now be unavoidable. \n\nThose who say war is unthinkable are right. Military strikes, even limited, targeted and accurate ones, will have devastating consequences for the region and for the world.\n\nIf Iran gets safely and unmolested to nuclear status, it will be a threshold moment in the history of the world, up there with the Bolshevik Revolution and the coming of Hitler. \n\nAnd so we must ready ourselves for what may be the unthinkable necessity.
