I can start. My understanding is that SHIRBRIG hasn't turned out to be an efficient and effective measure there.
I agree with the implication that there needs to be some kind of collective readiness to deploy that is available, but I'm not sure as to the extent to which that's going to solve the problem of obligation. Through the UN resolution, states have accepted responsibility to act under chapter 6 and declare a readiness to act under chapter 7, but there have been comments about the unevenness of our response in various parts of the world, and that's a long way from an obligation.
I think in one sense we're down to the national interest, and the national interest is not a reliable guide for responding to conflict. There is some need for political leadership there and indicating the extent to which Canada does have an interest in constructive contributions to inner conflict, wherever it occurs internationally.
