Why do some attempts to conclude alliance treaties end in failure? From the inability of European powers to form an alliance that would stop Hitler in the 1930s, to the present inability of Ukraine to join NATO, states frequently attempt but fail to form alliance treaties. In Arguing about Alliances, Paul Poast sheds new light on the purpose of alliance treaties by recognizing that such treaties come from negotiations, and that negotiations can end in failure. In a book that bridges Stephen Walt's Origins of Alliance and Glenn Snyder's Alliance Politics, two classic works on alliances, Poast identifies two conditions that result in non-agreement: major incompatibilities in the internal war plans of the participants, and attractive alternatives to a negotiated agreement for various parties to the negotiations. As a result, Arguing about Alliances focuses on a group of states largely ignored by scholars: states that have attempted to form alliance treaties but failed. Poast suggests that to explain the outcomes of negotiations, specifically how they can end without agreement, we must pay particular attention to the wartime planning and coordinating functions of alliance treaties. Through his exploration of the outcomes of negotiations from European alliance negotiations between 1815 and 1945, Poast offers a typology of alliance treaty negotiations and establishes what conditions are most likely to stymie the attempt to formalize recognition of common national interests.

In the past twenty-five years, a number of countries have made the transition to democracy. The support of international organizations is essential to success on this difficult path. Yet, despite extensive research into the relationship between democratic transitions and membership in international organizations, the mechanisms underlying the relationship remain unclear. With Organizing Democracy, Paul Poast and Johannes Urpelainen argue that leaders of transitional democracies often have to draw on the support of international organizations to provide the public goods and expertise needed to consolidate democratic rule. Looking at the Baltic states' accession to NATO, Poast and Urpelainen provide a compelling and statistically rigorous account of the sorts of support transitional democracies draw from international institutions. They also show that, in many cases, the leaders of new democracies must actually create new international organizations to better serve their needs, since they may not qualify for help from existing ones.
