Poland’s foreign minister, Radosław Sikorski, has proposed the creation of a “European legion”, which would be made up of soldiers from European Union member states and even countries that are candidates to join the EU. He argues that forming such a force would be more realistic than the idea of creating a full European army, as was recently advocated by EU defence commissioner Andrius Kubilius. However, the recent dispute with President Donald Trump over Greenland has raised questions about the extent to which Europe can rely on the United States. Similarly, NATO Secretary General Mark Rutte said earlier this week that a European army would “make things more complicated” and result in “a lot of duplication”, reported Reuters. By 2024, Poland had NATO’s third-largest military in terms of personnel, behind only the United States and Turkey.
