The reflection submitted in this article is the result of two observations. First, the Sahel is undergoing transnational threats that are materialized through chaos in Libya and in Mali. Second, the increased number of actors that influence international relations have lead to the reconfiguration of the international system and undermines US supremacy, especially in relation to security. In light of this evolution and the multiple unknowns of the Sahel equation, the United States and the European Union offer different viewpoints in order to meet the needs of a complex situation in regards to crossed and inclusive approaches. It is therefore necessary to reconsider the efficiency and consistency of the different strategies drawn up for the Sahel due to the fact that the Sahel has become an area of danger and a place of resurgence of violent extremism at the international level.
