Event Description

Existing theories of alliance formation explain alliances as being caused by a changing balance of power, balance of threat, or balance of interests. These structural theories do not account for the role of leaders’ agency in alliance formation. By contrast, she analyzes the causal role of leaders in alliance formation. She develops a new method—probabilistic counterfactual analysis—to identify alliances in which a leader caused the alliance, and alliances in which leaders did not cause the alliance. Her primary cases are Japan in the Anglo-Japanese Alliance (1902), in the Tripartite Pact (1940), and in the renewal of the US-Japan Alliance (1960). In her presentation, she will introduce probabilistic counterfactual analysis as a method, demonstrate the application of this method in the case of Japan in the Anglo-Japanese Alliance, and provide a summary of her preliminary conclusions from additional cases.
