Guys
I just re-read this thread and it is one of the best - and it spawned the 'what's your drink'.
The main theme seems to be the legitimacy or otherwise of killing civilians. Going back through history whether it was the Romans ruthlessly destroying anyone who fought back 'over their line in the sand', the thirty years war depopulating Germany in the name of religion (some part to play in the US early development?), Napoleon and his tactic of 'living off the land', the British naval blockade of continental Europe starving people (pick your century), the German U boat blockades of Britain (only a few weeks food left in 1917), the US submarine blockade of Japan (same - did they need the bomb again?), Hilter's quest for Liebensraum, or the development of guerilla war/terrorism when you cannot defeat an army (Vietnam springs to mind until the US pullout, and the Penninsular War from a Spanish perspective) - the problem has always been wrong place wrong time for civilians and man's inherent inhumanity in authoritative positions.
The most recent difference is perhaps the attempt to impose law and a legal system before, during and after the event - but see Louis' comments about the US legal system - change 'US' for any other jurisdiction..... If this debate exists given the extreme circumstances of global conflict in WW2, where does that leave us since then?
Perhaps conventional battles are too difficult to fight just now so we have even more difficult issues to face with greater incongruity and hipocrasy. Did the Romans have to bother about CNN and Al Jezera, or the media in Vietnam?
When it comes to making war, armies are trained and are designed to apply maximum force - teaching minimisation of force whilst putting troops in a war situation is perhaps more difficult than we realise? The British learned this to some extent in Ireland after many mistakes, but it goes some way to explain the normalisation in a battle sirtuation of what is otherwise completely abnormal. I'm not seeking to condone for one second, or even explain - maybe just trying to understand a little.
One test already referred to - if this was your country and kin what would you do......
