I'm sure it goes without saying that of course everyone on this thread 'cares'. I care hugely about human suffering (esp civilians). I'm haunted by things I've read over the years which I won't type out hear so as not to pass on that trauma to others, but basically atrocities happening to poor tribal people across the globe.
But what to do about it? What honestly could Britain or The West have done to stop the vile things I heard logging companies were doing to terrorise Amazonian tribes (beyond cruel)? The UN is supposed to be the mechanism for intervening in humanitarian tragedies - but it moves at the pace of a snail because it has to be democratic and also China and Russia have a place on the Security Council and they MOST DEFINITELY DO NOT have the same attitude to human suffering as most of us do in Western Europe. And they are sometimes behind the people committing these atrocities - in a proxy way.
Humans can be horrible. Throughout history and prehistory we've slaughtered each other in terrible ways. I don't know what you do about it. As has been said, the political climate has changed over the last 20 years and any intervention in, say, Africa, is now viewed as imperialist white-saviourism (look at the view taken now of Live Aid! - they've really turned on that inititative).
The West is in decline and the 21st Century will belong to China, mainly. We're seeing the first effects of this right now and we don't like it. I'm not sure China feels any particular moral duty to check suffering across the globe!
