<p style="margin-left:19.85pt;">The transnational nature of security threats in the 21st Century are such that interorganizational cooperation is necessary to effectively combat these threats. This article explores a key organization, the Multinational Joint Task Force (MNJTF), charged with curtailing the threat posed by terrorism in certain parts of the Sahel and West Africa. Using the theoretical framework of Walt’s balance of threat and a combination of data obtained from ACLED and expert interviews, the article argues that the MNJTF has not been successful in achieving its mandate.
