Kat, who I linked before, has been answering some guestions posed by a war skeptic. Her answers expand a good deal on the original post and give one a much better idea of what the reconstruction in Iraq is like. Because the news coverage of this aspect of the war has been totally worthless I highly recommend reading what she has to say at My Thinking Corner.
Second in importance were vital services, such as electricity or repairs to damaged water and sewer systems. This proved to be substantially more difficult than initially expected, partially due to war damage but largely due to long-term neglect under Saddam. For example, it was not unusual to replace an obviously damaged valve on a water supply system only to find that once pressure was placed on the balance of the line, three other valves (not to be found anywhere in Iraq) promptly blew, or whole sections of pipe split, or leaks developed around hundreds of packing joints and gaskets.
Yeah, that was for you civil engineering and construction geeks.
Update: (From MeaninglessHotAir) Kat's comments on Thinking Corner may well be the best thing you will ever encounter on this blog. Drop everything and read them now, and forget for a moment all the other dreck out there on television, in the newspapers, and, yes, even on this blog.
