It's useful to recall that the UN was built to replace a failed League of Nations, who was seen to have failed at preventing World War II. For those who lament the death of UN multilateralism, who might even call it a post - World War II artefact, I don't believe that's the case. Global multilateral forums are still important, and the charter itself holds a lot of tools like the Chapter VI powers, which are really valuable when exercised in efforts to de-escalate conflict. But there's a clear need for a matured charter in today's world, and a number of speakers tonight have spoken to that. It's becoming clearer that we also need a framework for autonomous sanctions.
