The part about shaheds is such a ridiculous take, they're an economic inconvenience not a serious military threat.
FPV drones? You don't need good defense against them, it'd be nice to have, but EU military doctrines broadly assume aerial superiority enabling effective combined arms operations and maneuver warfare. Hostile operators of fiber optic drones aren't going to have a great time in such an environment.
But sure, EU would have a bad time without US support given that EU ammunition stocks probably aren't deep enough for proper DEAD.
