Of course, when I was at school, our leaders – Attlee, Churchill, Eden, Macmillan, or Truman, Eisenhower and Kennedy in the United States – had real experience of real war. Not a single Western leader today has any first-hand experience of conflict. When the Anglo-American invasion of Iraq began, the most prominent European opponent of the war was Jacques Chirac, who fought in the Algerian conflict. But he has now gone. So has Colin Powell, a Vietnam veteran but himself duped by Rumsfeld and the CIA.
Yet one of the terrible ironies of our times is that the most bloodthirsty of American statesmen – Bush and Cheney, Rumsfeld and Wolfovitz – have either never heard a shot fired in anger or have ensured they did not have to fight for their country when they had the chance to do so. No wonder Hollywood titles like "Shock and Awe" appeal to the White House. Movies are their only experience of human conflict; the same goes for Blair and Brown.
Churchill had to account for the loss of Singapore before a packed House. Brown won't even account for Iraq until the war is over.
It is a grotesque truism that today – after all the posturing of our political midgets five years ago – we might at last be permitted a valid seance with the ghosts of the Second World War. Statistics are the medium, and the room would have to be dark. But it is a fact that the total of US dead in Iraq (3,978) is well over the number of American casualties suffered in the initial D-Day landings at Normandy (3,384 killed and missing) on 6 June, 1944, or more than three times the total British casualties at Arnhem the same year (1,200).
They count for just over a third of the total fatalities (11,014) of the entire British Expeditionary Force from the German invasion of Belgium to the final evacuation at Dunkirk in June 1940. The number of British dead in Iraq – 176 – is almost equal to the total of UK forces lost at the Battle of the Bulge in 1944-45 (just over 200). The number of US wounded in Iraq – 29,395 – is more than nine times the number of Americans injured on 6 June (3,184) and more than a quarter of the tally for US wounded in the entire 1950-53 Korean war (103,284).
Iraqi casualties allow an even closer comparison to the Second World War. Even if we accept the lowest of fatality statistics for civilian dead – they range from 350,000 up to a million – these long ago dwarfed the number of British civilian dead in the flying-bomb blitz on London in 1944-45 (6,000) and now far outnumber the total figure for civilians killed in bombing raids across the United Kingdom – 60,595 dead, 86,182 seriously wounded – from 1940 to 1945.
Indeed, the Iraqi civilian death toll since our invasion is now greater than the total number of British military fatalities in the Second World War, which came to an astounding 265,000 dead (some histories give this figure as 300,000) and 277,000 wounded. Minimum estimates for Iraqi dead mean that the civilians of Mesopotamia have suffered six or seven Dresdens or – more terrible still – two Hiroshimas.
Yet in a sense, all this is a distraction from the awful truth in Buchanan's warning. We have dispatched our armies into the land of Islam. We have done so with the sole encouragement of Israel, whose own false intelligence over Iraq has been discreetly forgotten by our masters, while weeping crocodile tears for the hundreds of thousands of Iraqis who have died.
America's massive military prestige has been irreparably diminished. And if there are, as I now calculate, 22 times as many Western troops in the Muslim world as there were at the time of the 11th and 12th century Crusades, we must ask what we are doing. Are we there for oil? For democracy? For Israel? For fear of weapons of mass destruction? Or for fear of Islam?
We blithely connect Afghanistan to Iraq. If only Washington had not become distracted by Iraq, so the narrative now goes, the Taliban could not have re-established themselves. But al-Qa'ida and the nebulous Osama bin Laden were not distracted. Which is why they expanded their operations into Iraq and then used this experience to assault the West in Afghanistan with the hitherto – in Afghanistan – unheard of suicide bomber.
And I will hazard a terrible guess: that we have lost Afghanistan as surely as we have lost Iraq and as surely as we are going to "lose" Pakistan. It is our presence, our power, our arrogance, our refusal to learn from history and our terror – yes, our terror – of Islam that is leading us into the abyss. And until we learn to leave these Muslim peoples alone, our catastrophe in the Middle East will only become graver. There is no connection between Islam and "terror". But there is a connection between our occupation of Muslim lands and "terror". It's not too complicated an equation. And we don't need a public inquiry to get it right.
