ABSTRACT (Continue on reverse if necessary and identify by block number) This study examines problems which the United States faces in its support of efforts by governments in less-developed count, ies (LDCs) to defeat revolutiona.y insurgents. The US has in the past been drawn into supporting conflicts for a protracted period, at increasing political, economic, and military cost, without receiving apparent benefit nor approaching a favorable end to the conflict. This thesis attempts to answer the questions of why the US encounters problems In its support of counterinsurgency efforts and why it has difficulty in effectively terminating this type of low-intensity conflict (LIC). This study makes the assumption that to achieve the long-term goals of stability, democracy, reduced conflict and reduced dependence on US assistance, the best outcome for the US in most cases of insurgency is to obtain a negotiated settlement to end the conflict. After producting a list of factors necessary to produce a negotiated settlement to terminate an insurgency, the study examines the various COIN counter-insurgency strategies used in El Salvador to see how they affected the factors indicating progress toward achieving a settlement. The study concludes that while the US has improved in its COIN strategies by developing a combined strategy which emphasizes other than military efforts, limiting its direct military involvement, and increasing the use of small-unit tactics and other appropriate LIC methods there are problems within the US military and political organizations which inhibit the US ability to achieve effective termination of the insurgency and of its support efforts. These problems include the lack of consistent pressure on the host government and military to 20 DISTRIBUTION/AVAILABILTIY OF ABSTRACT - 1 a. ABSTRAC r SECURITY CLASSIFICAT!O.

Bruneau, Chairman, Department of National Security Affairs iii ABSTRACT This study examines problems which the US faces in its support of efforts by other governments to defeat revolu- tionary insurgents. The US has in the past been drawn into supporting conflicts for a protracted period without receiv- ing apparent benefit nor approaching a favorable end to the conflict. This thesis addresses why the US encounters problems in its support of counterinsurgency efforts and why it has difficulty in effectively terminating this type of low-intensity conflict (LIC). This study assumes that the best outcome to achieve US long-term goals in most cases of revolutionary insurgency is a negotiated settlement. The study develops a list of factors considered necessary to produce a negotiated settlement of an insurgency. It then examines the various counterinsurgency strategies used in El Salvador, analyzing their effects on the factors needed to achieve a settlement. The US has improved its approach to counterinsurgency. However, there are problems within US military and political organizations which inhibit the US' ability to achieve effective termination of an insurgency. These include the lack of consistent pressure on the host government and militazy to reform and to compromi3e on settlement conditions and the desire within the US administzation to achieve a military victory. iv TABLE OF CONTENTS I.
