Look at the raw data. Same steady low level violence for three years. That is the sign of an "insurgency" that cannot evolve or grow. They are stuck in stage 1 guerrilla warfare. They can kill people and cause pain, they cannot evolve. Meanwhile the Counter Insurgency political structure is rapidly growing. The terrorists can continue to kill but they cannot win. The raw data below shows the utterly LIE in the DNC directed Junk Media spin lie about "Iraq on the verge of a civil war".
