How long?

I have been watching the brilliant, but occasionally farcical, The Passing Bells. A drama about a young German lad and a young British lad who volunteer in WW1. Whilst watching accounts of these young men, some as young as fifteen, going off to war and the pain felt by their families left behind I had a chilling thought; how long before our children have to go off and fight a war. A whimsical thought you may think, but just look at the world today, what would it take for all the current conflicts in the Middle East to merge into one major conflict that draws all the world in? Not that much I am sure and that is disturbing. Jesus said that "blessed are the peacemakers" and the time is long overdue for the politicians of this world to stop thinking about their own careers and pushing their own personal, self-seeking agenda's, and to start thinking about how peace can be brought about in our troubled world. I accept that this may mean further and greater conflict, even though I find this distasteful, but something must be done to halt the ever-decreasing circle of violence and hate that will eventually see the children of all nations going off to war on a global scale.
