Abstract
This paper seeks to enrich understandings of middle-power security strategies by examining countries that lack great-power capabilities but still aim to influence the regional security environment. Based on a literature review highlighting the functional and behavioral approaches of middle power diplomacy, we note that these elements could also apply to their regional security strategies. The paper focuses on regional security strategy as a subset of foreign policy and asks why some middle powers appear to go for a regional security strategy that is more functional while others adopt a strategy that is more behavioral. It argues that this divergence derives primarily from differences in resource availability and strategic environment. An analysis of Indonesia, South Korea, Australia and Vietnam highlights how each of these middle powers has adopted a particular regional security strategy, driven by their resource availability and strategic environment.
