I'm not sure I can put a measure on it, but I would say considerable.
The classic peacekeeping hasn't existed for a very long time--the idea that we have two opposing societies, or states, or portions of the state, and we need blue-helmeted people standing in between keeping them separated until they settle their differences politically. I wouldn't suggest it couldn't occur again, but the reality is that it hasn't occurred for a very long time. It's a much more complex world. If Canadians believe that we can send the youth, the young blood of this country, off to those other regions of the world and that's all we need to do--we don't need to give them weapons, we don't need to give the tools of the trade, as it were, and we don't need to give them the moral backing to do it--we're killing them for nothing. I mean, they will die for nothing.
I remember going into a UN mission where, sadly, I had troops who were not prepared to do that. It was one of those, and many have seen it happen, where we cobbled the mission together for a number of reasons—this is many years ago—and we sent them off to do it and they weren't capable of doing the job. If you did that today, the number of people we've had come home in coffins would have been manyfold greater.
So we can't afford it. It is a myth. You need people out there who are able to look after themselves and use force where it is necessary. It doesn't mean we're going out to kill people. Ideally we can get around it, but you'd better be prepared to.
