The September 11, 2001 attacks in the United States have liberated an encompassing rhetoric globally which designates all that is 'Muslim' or perceived to be such as a threat. The securitizing perspective, intertwined with debates over Muslims' integration and increasingly visible religiosity has led to growing suspicions regarding Muslims' loyalties in Europe. This analysis seeks to characterize this securitizing perspective and considers on the one hand, the inherent equalisation of increasing Muslim identity awareness with disloyalty and on the other hand, the depiction of Muslims in Europe as a homogenous block which facilitates constructing them as the 'Other'. As an illustration, this paper focuses more particularly on France and Great Britain.
