It's a fact that Saddam Hussein never had a nuclear program and his conventional military programs were quite pedestrian.
Many of these unarmed civilians were not assassinated because they were working on weapons of mass destruction ... they were assassinated because they might have the innate potential to do so.
This doesn't just happen in Iraq. Far from it.
"They worship snakes and phallic symbols equally and sacrifice their own kind liberally to these idols, believing themselves to be created by same."
"When they observe a man who excels through quickwittedness and knowledge, they say: 'for this one it is more befitting to serve our Lord.' They seize him, put a rope round his neck and hang him on a tree where he is left until he rots away."
- Ibn Fadlan,
(Arabic scholar writing on customs he observed amongst the Khazar people)
"There is nothing mysterious about the cruel treatment meted out by the Bulgars (Khazars) to people who were overly clever. It was based on the simple, sober reasoning of the average citizens who wanted only to lead what they considered to be a normal life, and to avoid any risk or adventure into which the 'genius' might lead them." He then quotes a Tartar proverb: 'If you know too much, they will hang you, and if you are too modest, they will trample on you.' He concludes that the victim 'should not be regarded simply as a learned person, but as an unruly genius, one who is too clever by half.' This leads one to believe that the custom should be regarded as a measure of social defence against change, a punishment of non-conformists and potential innovators."
-Turkish orientalist Zeki Validi Togan, academic authority on Ibn Fadlan
Think about the effect that centuries of this kind of behaviour would have on your gene pool. Think about what sort of people would be produced by it.
Here is a Tartar proverb about the Khazar people over a thousand years old on that very subject:
"If you know too much, they will hang you, and if you are too modest, they will trample on you."
Think about a thousand years of genetic engineering based on this principle.
