The treatment of Afghan prisoners shows the brutal face of US imperialism.
So there we have it! A 'war against terrorism' turns out not to be a war at all. A 'war of precision' turns out to be a war of totally indiscriminate killing, and a 'war for civilised values' ends up with the most brutal and uncivilised treatment of the enemy.
Somehow it is meant to be the opponents of the war who got it all wrong. All those who thought it a civilising mission are apparently in the clear, despite the evidence in front of their very own eyes.
