John Keegan

We can't walk away, even after 100 dead: "Critics should remember that, in nine tenths of Iraq, peace reigns. Thousands of Iraqi towns and villages are untroubled by insurrection and continue to regard the British and Americans as liberators. They cannot be abandoned to terrorists, fanatics and friends of the defunct dictatorship. To urge that we should go on as we are is an unpopular line of argument. That it is unpopular does not, however, mean it is wrong."
