2020s European rearmament
During the 2020s, there has been a significant strategic realignment in European defence policy, particularly accelerating in 2022 and 2025 due to the ongoing war in Ukraine and geopolitical policy shifts during the second presidency of United States president Donald Trump.
This transformation is characterised by increased localisation of defence manufacturing, defence investment of research and development, reindustrialisation of economy, and initiatives for greater military integration among European Union member states, with the intent of rehabilitate autonomous European defence capabilities independent of NATO or without the United States.
