Today we celebrate the International Day for the Elimination of Violence Against Women. Two weeks ago on Armistice Day we remembered those who died in the wars of last century and this. In just over two weeks' time the Nobel Peace Prize will be presented in Oslo to three women. The connection is this. A century ago 80% of the casualties in war were soldiers, 20% were civilians; today that ratio is reversed. In war zones such as the Democratic Republic of Congo, the death toll has reached more than 5 million - the worst humanitarian crisis since World War II - where one of the main weapons of war is rape.
