To share a few words to the delegates of NHSMUN: First, thank you for doing it. The UN is a vital global institution. It better work because we have to figure out ways to make this planet work together, and that’s the way we get 193 countries around the table and try as we might to get global agreements on critical issues—exactly the task you face as the ambassadors and UN leaders in the Model United Nations.
