The United States military campaign against the Islamic State does not quench the theories circulating on the streets of Baghdad and in the highest levels of government, according to them, it is the CIA who created and support the extremists. 

"We know who created Daesh" said to the newspaper The New York Times' Bahaa al Araji an Iraqi Deputy Prime Minister, using an abbreviation for the Arabic Islamic State. 

The politician attended Saturday a demonstration called by the Shiite cleric Muqtada al Sadr to warn against the possible deployment of American ground troops.

In a speech delivered last week, Sadr publicly blamed the CIA for creating the Islamic State, while surveys of most of the few thousand people that nourished the demonstration, including dozens of members of parliament, suggest that they support the same hypothesis.

The prevalence of theory in the streets of Iraq highlights the deep suspicions before the return of the US military Iraq more than a decade after the invasion in 2003.

Obama has pledged not to send combat troops to Iraq, but seems to have convinced few Iraqis. "We do not trust him," says Raad Hatem, a local of 40 years. Al Assadi agrees with him: "The Islamic state is a clear establishment of the United States, and the United States is trying to intervene again under the guise of the Islamic state."

According to him, Shiite militias and volunteers were already answering the call for religious leaders to defend Iraq against the Islamic State without American help.
