This chapter examines issues within the wider field of peace operations, focusing on gaps and policy problems of legal regulation. Section II begins by looking at frictions that evolved during the genesis of these operations and their current legal challenges. Section III takes a critical look at the existing legal basis and political control of these operations. Section IV comments on the status of peacekeepers in the host country and in transit states. Section V examines select issues of applicable law and policy for the conduct of peace operations. These include security and safety; command and control; freedom of movement, communications, and logistic support; and relevant operational law issues including compliance by peacekeepers with human rights obligations, protection of civilians, force protection, and operational detentions. Section VI discusses problems concerning the accountability of sending states, international organizations, and individual wrongdoers in context with fact-finding, judicial control, and the desirability of their improvement. Finally, Section VII draws some conclusions, focusing on implementation gaps and desirable legal developments.
