A report prepared by the Institute of Public Affairs in cooperation with the Heinrich Böll Foundation presents key findings of a new public opinion survey conducted simultaneously in Poland, Germany, and France. The study explores how citizens in the three countries perceive the significance and role of the Weimar Triangle. The findings point to clear public support for further strengthening cooperation among the three countries. At the same time, they highlight its greatest weakness: the Weimar Triangle remains relatively little known and has yet to become a visible part of citizens’ everyday experience.
