CEP Senior Director Dr. Hans-Jakob Schindler writes: "Sanctions or restrictive measures in European Union (EU)  terminology have become a key instrument in the toolbox of policymakers, including policymakers in the EU. Often the public discussion centers on sanctions implemented against governments of countries such as Iran or the Russian Federation. In Europe, counterterrorism sanctions measures receive far less public attention and are mainly addressed when challenged in European courts. However, sanctions measures can be used to disrupt terror organizations’ ability to function by targeting a set of key individuals that facilitate the functioning of the group."
