Making It Personal: The Role of Leader-Specific Signals in Extended Deterrence.

This article explores how a major power’s leader can deter challenges against weaker states using “leader-specific” signals of support. These signals are sent by a leader personally and publicly, so that the leader becomes associated with the signal in the eyes of the public. Leader-specific signals can be a valuable tool for achieving credible extended deterrence because they are flexible, and they create personal audience and reputational costs for leaders. I focus on leader visits abroad as the type of leader-specific signal that is most likely to be credible. I use original data recording leadership visits in a statistical analysis of extended deterrence success 1950–2007 and find that these visits have a significant deterrent effect. This is particularly true when a visit is accompanied by a high level of supportive statements and when the visit recipient also has a major power defense pact. [ABSTRACT FROM AUTHOR]
