Polish President Andrzej Duda has called on NATO member states to give Kyiv a clear roadmap to joining the defense alliance. "Ukraine is waiting for an unambiguous signal regarding a clear prospect of membership in NATO," Duda said on June 12 after a meeting with French President Emmanuel Macron and German Chancellor Olaf Scholz in Paris. The tripartite meetings involving Germany, France, and Poland, known as the Weimar Triangle, began in 1991 in Weimar, Germany. The talks initially sought to bring Poland and other Eastern European states closer to the European Union and NATO.
