I would like to comment on that.
There is definitely a difference between the Iraq War and the Afghanistan War. If I had been stopped, lost, and brought back into the military, and they said, you're going to Iraq rather than Afghanistan, I wouldn't have gone wilfully or happily, but I would have gone because I believe that's a justified war--to me. Many people don't, and I respect that.
In terms of what you do when Canadian soldiers come back and they want to refuse to fight in the war on Afghanistan, from my small research, I did find out from talking to people that there is a method in the Canadian Forces that allows you to say, “I'm opposed to this war”, and they can reassign you or transfer you to a different unit. That's my understanding.
