10 years down the road. What was achieved.
US bases in the Middle East.
Destabilisation of Iraq
Major oil companies, plus the chinese safely ensconced in the Rumaila field and elsewhere.
nano sized depleted uranium particles powdered about where ever
significant fighting occurred.
Genetic damage inflicted on the population because of the uranium.
Many people killed.

This outcome was fairly predictable. Perhaps the outcome gives a reason for the invasion.
The mainstream media will give many reasons that appear reasonable. However the real truth is found under stones in the shadows.
