Military maneuvers as a costly signal for alliance reliability

Margit Bussmann, Chair of International Relations and Regional Studies at the University of Greifswald, presents her research on whether military exercises among allies strengthen the alliance's credibility. This event is part of the International Security Research Colloquium hosted by the Centre for International Security.

Military alliances, in particular defensive pacts, are an expression of intent to come to each other’s help in case an alliance member is attacked. Formal agreements of military assistance, however, are frequently reneged and there is a high degree of uncertainty about alliance reliability. Assessments of an alliance partner’s intention are particularly crucial in the context of extended deterrence. Costly signals can help with the interpretation of the intention and enhance credibility of alliance commitments. Various such costly signals can be conveyed, one being military maneuvers. Military exercises carry high costs ex ante and ex post and can be a mechanism to convey a credible signal of resolve to an adversary; and in case of extended deterrence a signal to allies that the protection will hold. This adds credibility to alliances. With the help of quantitative analysis using data on multilateral military exercises from 1977-2016 we will assess whether more exercises among alliances partners contribute to less alliance violations. Our results provide some first support for this expectation, also if we exclude dyads consisting of NATO members.
