At the beginning of this war, I was not sure it was the right thing for the US to do. In true FR spirit, I got two books Saddam: King of Terror by Con Coughlin and Rebuilding Babylon by idontremember. After reading both books, the only questions I had were: why was a single Iraq carved out of Persia instead of three separate countries and more importantly why wasn't he removed from power in 1991. One out of two is better than nothing.
I know the answer to your question, however, it takes many, many pages to respond.
I suggest reading the history of the Sumerians and then proceeding with the history of the middle east from the time of the heretic until present times. Please note: Sumeria was spelled as Schumeria or Schumer, as in Senator Schumer.
I think there is a link.
Regards.
