Afghanistan
It appears to me, from reading this thread and many others like it, that in order to declare oneself a genius and master of military history and doctrine all one has to do is to point out that Britain (and other nations throughout history) have ventured into Afghanistan in the past.
We all know this. This is a military forum and, besides, Wikipedia has told us anyway.
Unless there is something Earth shattering and can clearly be demonstrated to have been foretold (I’m thinking the Mayans and 2012 - although thankfully that was wrong) can we stop pointing out, in a pseudo-intellectual way that Britain has, in fact, fought a war in Afghanistan before?
