In this exploratory study, a representative community survey of 319 registered voters was conducted in the island of Guam to analyse the relationships between colonial debt (an internalised acceptance of colonisation), resistance to U.S. military presence, support for an impending U.S. military buildup in the island, and the perceived trustworthiness of information sources supportive of the buildup — that is, U.S. officials and the Pacific Daily News, a local newspaper. Results suggest that colonial debt was associated with less resistance to U.S. military presence, more support for the military buildup, and higher trustworthiness of two information sources supportive of the buildup. Resistance to U.S. military presence was linked with less support for the buildup and less trustworthiness of the two information sources. Implications and limitations are discussed.
