Here is another one-dimensional way of thinking : A piece that never mentions the why (i.e. the geo-politics, the global and regional context, the so-called 'national-interest' cover or motive, etc) behind the belief, but focuses on the individual's neurons and the way that belief is held. Note also that Blair is a trained barrister by profession. His main skill is to know how to plead in court, using arguments and rhetoric not just knowledge of the legal system. Lawyers in general work within the system and they rarely challenge it. In fact they work to justify it most of the time.
“The West won the world not by the superiority of its ideas or values or religion (to which few members of other civilizations were converted) but rather by its superiority in applying organized violence. Westerners often forget this fact; non-Westerners never do.” —Samuel P. Huntington, The Clash of Civilisation and the Remaking of the World Order, 1996, p. 51
