CIvil War?

This from Juan Cole sounds pretty much like civil war to me:

A battle between 100 guerrillas and Iraqi army forces in Baqubah (northeast of Baghdad) on Thursday left 30 persons dead, with casualties on both sides. Local Iraqi forces spoke of a guerrilla force as big as 500! It is unusual for guerrillas to field such a comparatively large force. Local Iraqis also said that US forces came in to aid them when called on. You have a sense that if the US troops weren't around to be called on, Baqubah would pretty quickly fall to the guerrillas altogether. I suspect the guerrillas were mostly Iraqi, not foreign jihadis.
