Understanding Current Operations in Iraq

From his latest post, quote by David Kilcullen:

"I know some people in the media are already starting to sort of write off the surge and say Hey, hang on: weve been going since January, we havent seen a massive turnaround; it mustnt be working. What weve been doing to date is putting forces into position. We havent actually started what I would call the surge yet. All weve been doing is building up forces and trying to secure the population. And what I would say to people who say that its already failed is watch this space. Because youre going to see, in fairly short order, some changes in the way were operating that will make whats been happening over the past few months look like what it isjust a preliminary build up."
