If you think the Taliban does not have an internet presence you are sorely mistaken.
While I doubt the coalition troops are in any danger from these documents, I do think there are a good number of villages that are in danger of reprisal attacks by the Taliban if they were to see the full documents.
What better way to find the right targets than to read the nicely formatted official reports of your enemy?
These military actions have been mishandled from the start and at this point every time we make a friend and try to help someone out we are just painting a target on their back.
The situation is complex, I'm not sure a good outcome is possible at this point, just pulling all the troops out will result in thousands of deaths due to our inaction and staying there is just prolonging the inevitable.
