Of course good things do come out of war, (unfortunately). Maxo-facial surgery was developed as a response to horrendous injuries in World War1. I'm sure many other medical procedures were refined on the horrifically wounded and dying. If yesterday's activity in Nevada suggests one thing. War produces an excess of high powered firearms. Military developments do filter through to civilian goods but I always wonder what amazing things could be achieved by a peace army. They should be the disaster zone angels everywhere. (they often are) with organisational, engineering and ordnance capabilities beyond everyone else. They should be saving Elephants from extinction, rebuilding Puerto Rico and a million other things. It's a sad world at the moment. I thought the 21st Century was going to be all sci-future peace and renewable energy.. Ah well, there's another 82 and a bit years to get there.. minus the elephants and most of the other animals in the world !
