There has been that sort of discussion going on. In the constitutional loya jirga back in 2003-04, there was a discussion about the best form of representation, what kind of system works. As you know, Afghanistan is a multi-ethnic country that is made up of a diverse group of cultures; it's not homogeneous by any stretch of the imagination. They're all looking for their place in society in their ability to have proper representation.
I think this is a discussion Canada could participate in and help facilitate in the country, but it's first steps.
