It is 25 years since the end of the Cold War, now a generation old. It began over 75 years ago, in 1944--long before the last shots of the Second World War had echoed across the wastelands of Eastern Europe--with the brutal Greek Civil War. The battle lines are no longer drawn, but they linger on, unwittingly or not, in conflict zones such as Iraq, Somalia and Ukraine. In an era of mass-produced AK-47s and ICBMs, one such flashpoint was the Middle East ... On the afternoon of 6 October, 1973, the colossus of the Israeli Defence Forces was awakened by a wave of airstrikes, followed by an artillery bombardment along the Suez Canal that preceded a meticulously planned Egyptian invasion of the Israeli-held Sinai. Simultaneously, a massive Syrian armored assault bore down on Israeli positions on the Golan Heights. The day was Yom Kippur, the most holy day on the Jewish religious calendar, and the commencement of a war that would bring the young state of Israel to the very brink of defeat. In the aftermath of the Six-Day War of 1967, a stunning Arab reversal at the hands of the untested Israeli Defence Forces, Israel occupied and held Arab territory on the West Bank, the Sinai Peninsula and the Golan Heights. These were for the most part territorial buffer zones, retained to protect Israel against an inevitable future war, but their ongoing occupation remained an open diplomatic wound. In the meanwhile, a mood of complacency came to affect the Israeli military machine, in the belief that air and armored dominance of the battlefield would, as had been the case in 1967, guarantee a quick victory in any future war. The Yom Kippur War proved the fallacy of this belief, revealing critical weaknesses in Israeli intelligence capability and battlefield strategy. The ferocity and effectiveness of the combined invasion pushed the much-storied Israeli armed forces almost to the point of collapse. Only the rapid resupply of arms and equipment by the United States, and a display of extraordinary reliance and determination by the fighting forces of Israel, rescued the young state from annihilation. The story of the Yom Kippur War is an object lesson in the dynamism of military thinking, the evolution of battlefield technology and the uneasy alliance of east and west during the Cold War era of d tente. Yom Kippur was both a military and political maneuver that adjusted the balance of power in the Middle East, and set the tone for the ideological standoff that continues in the region to this day
