There are few references to Canada in Margaret MacMillan's book "Paris 1919" - a book describing the peace talks that followed the Great War that documents quite well the origins of current Middle East conflicts.  The few there are reveal a post-war Canada deeply mistrustful of European involvements, angry over the great loss of Canadian lives and committed to Canadian control of life and death decisions in wars.  We learned 50 years later what the Americans learned in their civil war - modern war can be, and likely will be, hell on earth.  Those warmongers among us who like to send "messages" and demonstrate "muscularity" need to make their case based on reason and national interest, not on knee-jerk emotion and group think.
