This would be the job of the diplomatic surge, both to understand the situation more clearly and to encourage movement. Some have described the activity of Pakistan and India in Afghanistan as proxy fighting for what are in fact bilateral conflicts between them. Those sorts of activities need to stop. I would not for a moment promote the idea that Canada alone can mount a white charger of diplomacy and resolve that one. But it could, in concert with others, move in that direction and encourage those sorts of things.
Frankly, we also need to engage Iran. We need to engage Russia and China. They all have security interests, and unless there is this widespread diplomatic effort, the prospect of resolving the conflict in Afghanistan is probably remote.
