This is a war of attrition. How long can the US stay ?! Indefinitely is not an answer. It costs $100billion +++ annually for this little hobby. The US$ has turned to mush already. No matter how long you stay, Al sadr will still be there. HE LIVES THERE !!! So yeah, he will be the voice of the Shiite majority. If fact, don't be surprised to see him run for head office in Iraq in the future. Don't be surprised to see him win. The US has released a genie from a bottle that you simply can't get back in.
