During the 1980s, the major security themes that Caribbean scholars studied were geopolitics, militarization, intervention, and instability. The interface between domestic and international politics led to linkages among some of these themes and their domestic, regional, and international dimensions. For example, the militarization of Grenada in the 1980s was predicated on the need to defend the Grenadian revolution against foreign intervention and local counterrevolution. Ironically, the same buildup created the climate that led to the self-destruction of the revolution and presented the United States with a golden opportunity to intervene. In doing so, the United States succeeded in fulfilling a preexisting geopolitical aim of its own. Elsewhere in the region, militarization and concerns about stability in Dominica, Barbados, and St. Vincent and the Grenadines raised security concerns within the Eastern Caribbean, where several countries created the Regional Security System (RSS) in 1982 to bolster subregional security and became willing accomplices of intervention when the United States intervened in Grenada a year later.
