Nothing New Under the (Iraqi) Sun
Wherever you go in the world, people always blame most those with whom they most closely identify, and of whom they have the greatest expectations. This is human nature and an essential part of a working political system: complaints are leveled at those who are most directly accountable to the complainants, even if they are not the most responsible for the detrimental circumstances.
For example, U.S. political controversy about how to deal with Al-Qaeda involves almost no debate of the nature of the root cause – the organization itself – but plenty of debate on the actions of the Democrats, Republicans, President etc. in their attempts to deal with the problem.
Similarly, some of the Iraqi press is doing a decent job of being the fourth estate in a country that is struggling to establish the first three, is rightly determined to hold Iraqi representatives accountable more than they are determined to criticize the Americans who are most directly responsible for the current state of affairs in their country.
