I suppose this is true but it's shaving it a little fine. Canadian peacekeepers have been shot in various missions by parties in conflict (perhaps not technically by "enemies"); Canada has also lost troops in Afghanistan from friendly fire, suicide bombers, mines and bombs, and non-combat causes. Canadians have been killed in the Suez, the Golan Heights, Cyprus, Bosnia, and Haiti. Costall is the eleventh Canadian soldier killed in Afghanistan.

It's sad when it happens, but rich countries have a responsibility to promote peace, which sometimes means putting good men in the way of bad men.
