As I have said, in other threads, I think guess that Africa, somewhere in Africa, is our, Canada's, next stop. I suspect it will be less of a well thought out policy choice than it will be one of those opportunities that arrive when a crisis attracts public attention - UN and Congo have 'cheering sections' in Ottawa, including in the media - and provides some perceived immediate, partisan political advantage to the government of the day.
I am not as sure that we have any vital interests at all in Congo, or anywhere else in Africa for that matter. I am sure that Congo will be worse, in every aspect, than Afghanistan and that the media and the public will, quickly, turn against almost anything useful that might get done there because the costs in Canadian treasure, lives and, above all, in Canadian mythology will be too high.
