External: conflicts we cannot imagine what it must have been like to go through.
They are not external to us all though. Did you guys see the artists who raked sand stencils of the fallen 9000 of D-Day at Normandy? Link here a moving art piece. An extreme visual reminder of the cost of war.
Leunig is a national treasure, to use the most overused term of national endearment.
