How successful has Nato's strategy been in Afghanistan?
Under General David Petraeus, a major plank of Nato's International Security Assistance Force (ISAF) strategy has been "kill/capture raids" - lightning strikes on senior Taliban personnel to either take prisoner or kill.
But have they worked? Isaf supplies no consistent data on the policy, other than issuing a string of press releases claiming success after success, releases which often describe several raids in different places simultaneously. Researchers Alex Strick van Linschoten and Felix Kuehn wanted to find out exactly how the missions worked.
You can read their full report here. Frustrated by the lack of hard data, Strick van Linschoten scraped the reports, then used the Tinderbox database package to process each incident and extract the key numbers.
What he found is a very different picture to that described by Isaf press releases. "There are still relatively large numbers of Afghans subject to the capture-or-kill raids," he says.
Although, interestingly, there has been a decline in these raids since Petraeus left Afghanistan in July this year.
The report is a fund of data crucial to understanding the way Nato has fought the conflict. We've mapped some of the key facts by province, too.
This data, painstakingly collated, is the first time we can get a real picture of what is happening.
Aside from occasional scraps thrown to the media by ISAF, this is the first time that we have been able to get a somewhat more nuanced picture of how ISAF is operating, minimum figures for how many people are being detained and killed as well as a makeshift way to evaluate the usefulness of ISAF's own aggregate numbers that supposedly show the successes of the raids in Afghanistan.
