Three continuous posts on UN reform

I am creating three continous posts on UN reform. I am on a UN reform panel with a group of Washington think-tanks, all very bipartisan and distinguished. My particular role is a narrowly expert one on poverty reduction and economic development. But my own views on UN reform at the grand level of the vision of the UN itself are the subjects of these three posts. You can find post 1, here. Post 2 is here. Post 3 is here. What is missing from this analysis is what the response of the United States should be if there is no room for serious UN reform. How should it deal with what is the most likely scenario - the inability to reform, as we get in the windup to Kofi Annan's successor?
