Just to add that Hedges' is also very damning of the appeal of fear - it is a destructive addiction.
Having been through some hairy experiences I am very wary of giving 'fear as meaning' credibility or value. Would agree with the comment below - it is amazing how bad things can go and how very quickly.
Am also opposed to the aid worker-hero(ine) stereotype that is being promulgated. It distracts from the much larger sacrifices and bravery of people who live in the countries in which we work. People who risk often not only themselves but also their families and livelihoods.
