In response to the terror attacks, France invoked for the first time in the history of the EU the mutual defense clause of the EU’s Lisbon Treaty requesting military help from its European partners. Several months later, in June 2016, the European Council adopted a long-awaited “EU Global Strategy”, which calls for a stronger Europe in security and defense. This presentation places EU law in context of the new “EU Global Strategy” and asks what role “the use of force” rules of the Treaty of Lisbon should have and how we should interpret the solidarity and mutual assistance clauses in times of hybrid security threats in Europe.
