Kember wrote an account of his kidnapping, Hostage in Iraq, which was published in 2007. He himself considers it an irony that he travelled to Iraq to oppose the military intervention and was flown out of Baghdad in a military helicopter, guarded by machine guns. He also discusses whether his peace testimony has been compromised and what alternatives would have been at hand. In lectures and interviews, Kember states that what saddens him is the fact that he is alive and well, while people in Iraq, servicemen as well as civilians, are constantly threatened and many have meanwhile lost their lives.
