Europe's reliance on outsourced defense has ended, prompting a critical reawakening to the necessity of readiness for war. European NATO and EU members are now rapidly rearming and revitalizing their defense industries. This shift, driven by escalating global threats, includes significant innovation, from drones to repurposed civilian factories. Despite progress, production capacity must accelerate to close capability gaps and support allies like Ukraine. A stronger European defense industry, built on transatlantic and international cooperation, is crucial for credible deterrence. This ambitious yet achievable endeavor, leveraging collective economic and technological might, is paramount for ensuring security across Europe and North America.
