Canadian troops are largely regarded as well-trained and, therefore, properly suited to peacekeeping operations.
The second point is that we have no colonial baggage, and that's important to many of these belligerents. When we turn up some place, they'll often ask, as I was asked in Bosnia and sometimes in Egypt, “What the hell are you doing here? Why is Canada interested in this particular part of the world?” That actually plays to our favour, not having political baggage.
