Political leaders in the United States argue over the policy of intervention and the extent to which it should be involved in other countries' domestic conflicts. This study examined 31 in-trastate conflicts with 35 episodes of intervention by major powers spanning the period from 1991-2008 in order to determine how various conditions relating to intrastate conflicts and inter-ventions could indicate which method of intervention is most likely to be successful in achieving a third-party's desired outcome. Intervention methods were classified by level of involvement, either direct or indirect, and by mode of implementation, either multilateral or unilateral. Meth-ods of intervention were examined in specific conditions relating to the intensity of the conflict, the goal of warring parties, ethnic and religious divisions, etc. The analysis compared the success rates of each method of intervention in these conditions with the overall success rates of the re-spective intervention methods in general. The results suggest certain conditions change the effec-tiveness of intervention methods. Findings regarding specific conditions and intervention meth-ods provide potentially valuable information applicable to the decision making process of third parties regarding intervention in intrastate conflicts.
