Teribus, the real problem, is that America and Britain misjudged the feelings and intentions of the Shia,
Actually, they got it right the first time,from their perspective ,when they supported Sadaam,who did a good job of keeping the lid on Islamic fundamentalism.
Obviously the greed for Iraqi oil and a need for a stable base in the Middle East outweighed other considerations.
They are now in the position of having to fight the people we were told were being liberated, and I am sure the Islamic clerics had this all worked out well before the war started.
As Chief Chaos would say "Weve been outflanked again"..Cheers Ake.
