In the long run, genocide or attempted genocide on the part of one group over another doesn't work because you never get all of them and what it creates IN the people trying to kill a whole other group of people is a contempt for ALL life that shoots them in the foot eventually.
That's a really important point. I have just finished reading "The Great War for Civilisation" by Robert Fisk. He was, actually still is, Middle East correspondent. He worked for The Independent newspaper for a large part of his 30 year career.
His book is uncompromising in describing the horrors of warfare in that troubled part of the world. From the Armenian genocide by the Turks in 1918 through the massacres in the Palestinian refugee camps of Shabra and Shatila in 1982 to Saddam Hussein's gassing of 5000 Kurds at Halabja in 1988 to the countless attacks on civlilians by both Israelis and Palestinians
I was left with an awful sense of pessimism for the future. There seems to be a never-ending cycle of violence. The cheapness of human life is sickening.
If there was a god who ordered his army to massacre women and children he dehumanised them in a way from which they would never recover
