This book looks at the interventions of US forces in the Caribbean nations of Cuba, Dominican Republic, Haiti and Grenada between 1898 and 1998. It considers these interventions against the background of the relationships that Caribbean nations have historically shared with imperialist powers, looking specifically at US foreign policy towards the region for the period of the study. For each intervention, the causes, conduct and long term consequences are examined. The main question to be answered by the research is how Caribbean nations should now organize themselves to provide the response to national security issues which has traditionally been given by the US. In answering this question, the history of regional organizations is also considered.
