The conflict in Iraq has changed from a pre-
dominantly Sunni-led insurgency against
foreign occupation to a struggle for the divi-
sion of political and economic influence
among sectarian groups and organized crimi-
nal activity. As described in the January 2007
National Intelligence Estimate, the term “civil
war” does not adequately capture the com-
plexity of the conflict in Iraq, which includes
extensive Shi’a-on-Shi’a violence, al-Qaida
and Sunni insurgent attacks on Coalition
forces, and widespread criminally motivated
violence.
Some elements of the situation in
Iraq are properly descriptive of a “civil war,”
including the hardening of ethno-sectarian
identities and mobilization, the changing
character of the violence, and population
displacements.
