I know there have been some 'bad' events but on the bigger scale of things I think the war has so far gone remarkably well. If the reports are to be believed then major resistance has crumbled and, althought there is still a lot to do, it does not appear to be turning into the street-by-street bloodbath that some feared.
Whether it will be judged truly successful will, of course, take many years and will largely depend on how things get off to a good start or not with any interim government.
The troops have done a great job ... let's hope the politicians don't flush it all down the drain.
