Drug trafficking, terrorism, criminal insurgency, hybrid warfare, refugees, and climate change trouble the Greater Maghreb, the area stretching across North Africa and the Sahel. David Garcia Cantalapiedra and a group of experts explain how these threats interact across Europes southern security flank, challenging the European Union and the states in the region. This outstanding collection of essays explains why the Greater Maghreb might just be ground zero when it comes to todays most pressing security issues. -- James J. Wirtz, U.S. Naval Postgraduate School The Greater Maghreb: Hybrid Threats, Challenges and Strategy for Europe provides an excellent updated and in-depth analysis of the southern neighborhood of Europe: the Maghreb-Sahel region, where most of the actual dangers, risks, and threats remain concentrated. -- Carlos Echeverrķa Jesśs, University Institute General Gutiérrez Mellado-UNED The Greater Maghreb appears to be as much a promising concept for the study of the North Africa and Sahel region as the Mackinder and Spykman inspired concepts of the Greater Middle East and the Greater Central Asia. If these described mainly a theatre of operations for the US, the Greater Maghreb is not a geopolitical and strategic response to other powers, but a useful and self-critical EU approach to the region from where the main threats and challenges to Europe are coming. -- Natividad Fernįndez-Sola, Georgetown University
