This is a war," Lemas replied. "It's graphic and unpleasant because it's fought on a tiny scale, at close range; fought with a wastage of innocent life sometimes, I admit. But it's nothing, nothing at all besides other wars - the last or the next.

I would say that since the war, our methods-out and those of the opposition-have become much the same. I mean you can't be less ruthless than the opposition simply because your government's 'policy' is benevolent, can you now?

For all the flailing and huffing and puffing, there is a kind of fatality about the process of war-making and the excuses we find for it, the consolation of belligerence in politics.

The Cold War was over long before it was officially declared dead.

You can't make war against terror. Terror is a technique of battle. It's a tactic that has been employed since time immemorial. You can conduct clandestine action against terrorists, and that must be done.

I worked for MI6 in the Sixties, during the great witch-hunts, when the shared paranoia of the Cold War gripped the services.

America has entered one of its periods of historical madness, but this is the worst I can remember: worse than McCarthyism, worse than the Bay of Pigs and in the long term potentially more disastrous than the Vietnam War.
