Which Ban Ki-moon -- the criticized early version, or the latest, emboldened edition -- will be seen during his second term leading the world body in pursuit of international peace and security? Although an in-depth treatment is beyond the scope of this article, in the hope of stimulating further analysis a few words can be said on the pivotal functions of the Secretary-General.
