Niche Diplomacy [PDF ebook] 
Middle Powers after the Cold War

An examination of the nature of middle power diplomacy in the post-Cold War era. As the rigid hierarchy of the bipolar era wanes, the potential ability of middle powers to open segmented niches opens up. This volume indicates the form and scope of this niche-building diplomatic activity from a bottom up perspective to provide an alternative to the dominant apex-dominated image in international relations.
