Barracks and barricades: how internal security threats affect foreign basing access in the Philippines

Abstract

ABSTRACT This paper presents a theory of foreign military basing as a function of the degree of internal threat facing a host nation. The theory is based on rational choice logic where politicians balance economic and security benefits against sovereignty and legitimacy costs. When internal threat is low a host nation’s political actors value legitimacy and sovereignty and hence reduce base access. When internal threat is high economic and security benefits trump legitimacy and sovereignty costs, hence increasing base access. The theory is assessed through process-tracing the historical events around U.S military basing in the Philippines. When internal threat was low from coups and revolutionary movements the Philippine government reduced U.S. basing access, but when a threat from these movements was high they either maintained or increased access. This study suggests more carefully considering the role of internal threats when assessing the dynamics of foreign basing.
