News Analysis
1. Terrorists/Insurgents
The insurgency is almost exclusively Sunni Arab-led and since Iraq's liberation they have targeted mostly civilians, but also troops and officials, through suicide bombings, car bombings and assassinations. Their goal is to destabilize the democratically elected government and alter the new democratic reality back to minority rule.
2. Militias
The militias, which are mainly Shi'i (although the Sunni Iraqi Islamic Party has an unnamed militia), have been blamed for sectarian killings and death squads – contributing to the increased violence. However, unlike the terrorists, their aim is not to change the new political landscape. Instead, they conduct random revenge attacks against perceived Sunni insurgents and their supporters and fill in the security vacuum in their neighbourhoods.While dealing with both the terrorists and militias is essential to improving the security situation, the former clearly represent a greater danger to Iraq's nascent democracy.
