In a post that will tend towards wild conspiracy theories I have a couple of things to suggest. Please bear in mind these suggestions are based less in reality and on information, and more on thoughtful paranoia.
The first, is it possible the four members of the Christian Peacemaker Teams were not kidnapped by Iraqi militia, but rather as part of a plot by the ‘Coalition’ to stir up fear and confusion, once again, among western whites over the Iraqi ‘Other’. The is even more compelling when you factor in that these people are a) Christian, a western, and especially American, ideal, and b) they are doing good work in Iraq, this makes the kidnappers heartless and devoid of morals for they will still victimise those who aim to protect them, yet they are facing execution.
Is it also then possible that the coincidence of this occurring at the same time as American officials are being questioned about secret CIA torture camps across Europe and the unusual flights that have been taking place moving prisoners around these camps, namely from countries where torture is outlawed to countries where torture isn’t. The kidnapping thus serves as a distraction, it increases the division between west and east and further otherises the evil enemy.
It is potentially damaging to consider all the information we are given to be true. We are at war, and war does not exist independent of propaganda.
