The use of IEDs (improvised explosive devices - mostly roadside and car bombs) peaked in October, at something around 3,200, the highest number employed by the insurgents ever. This was higher, by something like 15-20 percent, than any previous month. This massive use of IEDs was intended to disrupt the referendum on the new Iraqi constitution. Didn't work, but caused a spike in American and Iraqi casualties.
In the past,. IED use has peaked during the elections for the Iraqi Transitional Government and the delegated to the constitutional convention. It is believed that there will be a significant drop in the use of IEDs during November, as the terrorists rebuild their IED inventory and prepare for an "offensive" to disrupt the parliamentary elections scheduled for mid-December. However, this time, the IED surge may be much less than in the past. American troops, and Iraqi forces, have been making large inroads on controlling "terrorist territory" (Sunni Arab areas), capturing many IED workshops and quantities of bomb materials. The terrorists do not have unlimited resources. The terrorists, particularly the Saddam and Baath Party supporters, have lots of money. But they need people willing to take the cash to build, plant and set off the bombs. You need safe areas for the workshops, and competent people willing to carry out the attacks. There are fewer safe areas each week, and being in the bomb business gets more dangerous as well. This can be seen by the higher rates paid to people in the IED business, and the lower rate of success for IED attacks. Thus while the number of IED attacks were up in October, the percentage of successful attacks was down, and the casualties among IED users was up. By December, the Iraqi government expects to hammer the IED crews, and their inventories, even more decisively.

While the media makes a big thing about American combat deaths in Iraq, there are a lot of other people getting hurt, and killed. Not all the Americans killed in Iraq are military. So far, in addition, to some 2,000 dead troops, about 150 American civilians have died as well. Most of these men were security personnel, as were most of the non-U.S. contractors killed since 2003. The vast majority of contractors work inside the heavily protected American bases. Aside from security jobs, driving a truck is the most dangerous thing a civilian contractor can do. So far, some 4,200 civilian contractors have been wounded in Iraq (about half the rate of American troops).
The war in Iraq has been harder on Iraqis, with about 9,000 security personnel, and some 20,000 civilians (including terrorists and anti-government fighters, who comprise about a third of the dead civilians.) It's difficult to get an accurate count of dead civilians, for a number of reasons. First, a lot of people are getting killed by criminals, or because of feuds. Now some of the feuds are, technically, part of the war, because they involve political disputes. But many of these deaths are simply criminal, not military, events. But you can see how this gets murky. Moreover, some of the killing is accompanied by hiding the bodies. This was a favorite Saddam trick, and since the 2003 invasion, the bodies of 200,000 Iraqis, killed before 2003 and buried in unidentified graves, have been found. There's also the Moslem custom of burying the dead within 24 hours, and families of bad guys wanting to hide the death, of someone who was participating in illegal acts. If the police knew who died, and why, they might came around looking for more guilty parties. Terrorism, and criminal activities, are often family based.
Iraq has always been a violent place. But most Iraqis would like to get the Sunni Arab rebels calmed down, or killed, so everyone can enjoy some long sought peace and quiet.
