I have heard there was a time when some of the older veterans at today's Remembrance Day ceremonies thought there might be no more wars. They fought, and died, and killed, and saw the waste and destruction—and believed that perhaps the cost was too great. That nations and societies could decide to put the barbarism behind us.
There were young veterans at the ceremonies today, much younger than me, returned from Afghanistan and elsewhere. Sadly, I don't think they can share in that old idealism.
