Care for a few pointers? George W. Bush, 1978-84: senior executive, Arbusto Energy/Bush Exploration, an oil company; 1986-90: senior executive of the Harken oil company. Dick Cheney, 1995-2000: chief executive of the Halliburton oil company. Condoleezza Rice, 1991-2000: senior executive with the Chevron oil company, which named an oil tanker after her. And so on. But none of these trifling associations affects the integrity of God's work.

In 1993, while ex-President George Bush was visiting the ever-democratic Kingdom of Kuwait to receive thanks for liberating them, somebody tried to kill him. The CIA believes that "somebody" was Saddam. Hence Bush Jr's cry: "That man tried to kill my Daddy." But it's still not personal, this war. It's still necessary. It's still God's work. It's still about bringing freedom and democracy to oppressed Iraqi people.

To be a member of the team you must also believe in Absolute Good and Absolute Evil, and Bush, with a lot of help from his friends, family and God, is there to tell us which is which. What Bush won't tell us is the truth about why we're going to war. What is at stake is not an Axis of Evil - but oil, money and people's lives. Saddam's misfortune is to sit on the second biggest oilfield in the world. Bush wants it, and who helps him get it will receive a piece of the cake. And who doesn't, won't.

If Saddam didn't have the oil, he could torture his citizens to his heart's content. Other leaders do it every day - think Saudi Arabia, think Pakistan, think Turkey, think Syria, think Egypt.

Baghdad represents no clear and present danger to its neighbours, and none to the US or Britain. Saddam's weapons of mass destruction, if he's still got them, will be peanuts by comparison with the stuff Israel or America could hurl at him at five minutes' notice. What is at stake is not an imminent military or terrorist threat, but the economic imperative of US growth. What is at stake is America's need to demonstrate its military power to all of us - to Europe and Russia and China, and poor mad little North Korea, as well as the Middle East; to show who rules America at home, and who is to be ruled by America abroad.

The most charitable interpretation of Tony Blair's part in all this is that he believed that, by riding the tiger, he could steer it. He can't. Instead, he gave it a phoney legitimacy, and a smooth voice. Now I fear, the same tiger has him penned into a corner, and he can't get out.

It is utterly laughable that, at a time when Blair has talked himself against the ropes, neither of Britain's opposition leaders can lay a glove on him. But that's Britain's tragedy, as it is America's: as our Governments spin, lie and lose their credibility, the electorate simply shrugs and looks the other way. Blair's best chance of personal survival must be that, at the eleventh hour, world protest and an improbably emboldened UN will force Bush to put his gun back in his holster unfired. But what happens when the world's greatest cowboy rides back into town without a tyrant's head to wave at the boys?
