This is tragic for them, for their families and friends, and for the people of Aghanistan as it's going to speed the withdrawal from that unhappy country, and leave it to blunder back into the dark ages of Taliban-Warlord Hell. We mourn these deaths, because soldiers were sent there to fight a barbaric regime and it's terrorist acolytes. Whatever terribel things have been done by colaition soldiers in Afghanistan, whatever blunders there have been, and however it ends up (I'm betting; badly) there was a moral case to be made for them and that their deaths were in pursuit of some good end.
But also today, another 29 miners were killed in an explosion in China.
The connection might not be immediately obvious. But think about it. These men were working in the ramshackle, corrupt and deadly mining industry in China. Chinese mines drive the Chinese industrial boom, which in turn produces the apparently endless quantities of consumer baubles we're so hungry for. Without those baubles, our quality of life will take a hit; so I suppose you could say these miners also died in pursuit of - from our self interested point of view - some good end.
Last year, over 2,400 people died in mining accidents in the PRC - this is considered an 'improvement' on 2009. Never mind the other deaths related to mining, but which didn't actually happen in mining accidents, and the maimings and sickness associated with the industry.
Only I don't think you'll hear their deaths being discussed or mourned with quite the same intensity. After all, admitting our life style is based on driving people into death trap mines isn't something we're entirely happy thinking about too much.
