There are rumors that an Iranian drone-attack ship has approached off the coast of California, threatening to attack California with drones.

China's theory of armed (missiles, drones) civilian ships has unexpectedly become a reality so quickly, and they may even be deployed in actual combat.
This theory and practice of using disguised civilian equipment for sneak attacks deeply embody the essence of Sun Tzu's Art of War.
However, this approach of treating the masses as a strong backing like a copper wall and an iron barrier always seems despicable.
