It is approaching 90 years since the Great War ended, the world's first "total war", a global war. The casualties and loss of life were staggering. For years after many thought it was the war to end all wars.
And then came World War II.
Across the world today, millions of people are still caught up in wars. There are six conflicts currently causing more than 1000 deaths a year according to the UN classification. There are many more smaller conflicts, see Bruno Picozzi's Pro-Peace Initiative. The lesson has not yet been learnt.
Better than a thousand hollow words is one word that brings peace.
