The effectiveness of the economic sanctions – literature visualization on world map

One of the questions I have been dealing with since the second year of my Master’s Degree is whether the economic sanctions (imposed by the EU) can achieve foreign policy objectives or not. In other words, can these restrictive measures be considered effective or not in world politics? Of course, pundits have been debating over this issue for decades – most of them are painting a gloomy picture of the sanctions because, according to the majority of scholars, they are rarely capable of achieving breakthrough results.
