Thank you.
I agree that the United Nations certainly needs to be made much more effective. I don't know whether that means reform. I'm not sure whether you're using the term “reform” in a formal sense of institutional reform, which is a very difficult and long-tried but long-failed exercise. But effectiveness is critical, because the United Nations really remains the preeminent source of legitimacy for collective international operations, so it's essential.
One of the things we have to reconsider in Canada and other western countries is the degree to which we have tended to disengage from active involvement in UN-based peacekeeping operations. We need to re-engage there. There can be some sense of division of labour--some countries can provide troops and boots on the ground at less expense than western countries can--but there also need to be some actual troops on the ground from western countries to demonstrate it as a shared activity in which all countries have a stake.
If we continue to disengage from international collective operations led by the UN, we undermine the institution and implicitly look for an alternative. But it's the central institution that needs to be reinforced, and that means re-engagement with it.
