It is firstly important to distinguish between Bush and his neo-con Republicans and Americans generally. It is unfair to assume that all Americans are like Bush or like him.
It would seem that the Iraq situation has gotten out of control for Bush. He had hoped that he could put a puppet government into Iraq using Ahmed Chalabi (an old CIA stooge) but, with the conivance and interference of Iran, what we now have is a theocratic government of Ali Sistani - favoured by Iran.
Now Iraq really IS the fundamentalist hotbed the US government really did not want.
Way to go George! Still, just keep spying illegally on your own citizens. All the easier to impeach you then!
