The war of aggression launched by the Federation of Russia against Ukraine has not only raised the risk of projected threats from less than 1000 km of EU’s external borders. It also raised concerns about threats projected on internal affairs, national security and interest within EU Member States nationals borders. The main concern is about the capacities of the EU block to face the consequences this war implies regarding domestic and regional security. Although this war set the conditions encouraging the increased emergence of national security risks, the EU quickly reacted to tackle issues stemming from it.
