Germany's Bundeswehr is rearming at a scale not seen since the Cold War, and this DW Documentary report asks whether the money is going to the right things. Analysts warn Russia could be capable of attacking NATO territory within five to eight years, pushing German military leaders to set 2029 as the deadline for readiness. The film weighs whether expensive tanks and multi-million-euro fighter jets still make sense on a battlefield where cheap drones can destroy them, drawing directly on lessons from Ukraine. Interviews with military officials and defense analysts cover artificial intelligence in missile defense systems and the collateral-damage risks that come with letting algorithms make targeting judgments. Counterintuitively, the documentary reports that new weapons systems, despite promises of fewer soldiers needed at the front, actually demand more personnel because of their maintenance and complexity. It closes by comparing how Germany, NATO, and Russia are spending on military technology, and asking how much of it is genuinely justifiable.
