Europe is rethinking its security strategy as the war in Ukraine changes how governments view defense, deterrence and future conflict. In a discussion centered on these shifts, Andrius Kubilius points to Ukraine as a major source of lessons for European planners.

The focus is no longer only on traditional military strength such as tanks and troop numbers. The conflict has also highlighted the growing importance of drones, which have altered battlefield tactics and forced militaries to adapt faster than many had expected.

Space is emerging as another critical part of the security debate. As European countries prepare for a new era of confrontation, space-based capabilities are increasingly being treated as essential to intelligence, communications and broader defense planning rather than as a secondary concern.

Taken together, these changes suggest Europe is moving toward a wider and more modern defense posture. The debate described by Kubilius reflects a continent trying to absorb the lessons from Ukraine while preparing for threats that now extend from the ground to the skies and beyond.
