The nation that can destroy (or otherwise severely impair) the drone manufacturing/supply/operation capabilities of the opponent, wins a war that heavily includes drones. That's assuming the drones matter that much, which hasn't been demonstrated yet. Drones have not shifted the balance of power in Ukraine v Russia for example. It's no different than blowing up any other kind of weapons supply. You stop the supply, that's how you end the mass drone threat in that kind of war. You don't just endlessly trade hits from drones. That'd be like never targeting your opponents artillery production, or tank production, or cruise missile production, or jet production, or repair facilities, et al. Of course one side or the other will win a drone war, just like most any other war.
