Fighting a counter insurgency war in the enemy's homeland 1000's of miles from your own nation against a well trained, well equipped, fanatical enemy who has no regard for human life. Un-supported by a government who insist the conflict is winnable but refuses to support the front-line troops and give them the tools to take the fight to the enemy.
All this with the media focusing on the negative aspects of the war, public opinion fading and the sight of young men and women returning home, almost daily, in caskets. The forgotten hundreds of severely injured servicemen trying to rebuild their lives with little or no government assistance.
Didn't this happen in South East Asia in the 1960s and 70s ?
Afghanistan winnable?
