I have read a few reactions in the media to this incident and will add two below. Leaving aside the media focus and hype is this event really significant? I would say it is too early to say.

Where is the impact? In Afghanistan, the actual neighbourhood and beyond.

Given the criticism of US funded information operations here:http://circlingthelionsden.blogspot....perations.html I'd not be optimistic on our local and in country response.

The "Circling" author ends with:
It is remarkable that despite the massive spending on IO in Afghanistan in recent years, it is the Taliban that continues to make the running. It operates a highly successful propaganda operation using a multi-language website, twitter and a number of spokesmen who can easily be contacted and who issue timely statements well in advance of any that come from military sources. And all for a few thousand dollars.
Now to the two comments, first the BBC's North America Chief Correspondent:
This killing spree won't, by itself, lead to a quickening of the pace of a pull-out. But it may mean less heed will be paid to those like Senator McCain who think the war is winnable and who think the troops should finish the job before they leave.

The Daily Telegraph's Pakistan correspondent concludes:
This is not the make or break moment in Afghanistan. The danger is that it will be turned into one by American politicians wondering whether it is time to speed up the withdrawal.
