They already have. They are using drone tech to make massive swarms to attack naval fleets and bases and troops on the ground. They have the resources to pull this off. They have what the media calls a growing problem in video game addiction in their youth. They can easily supply thousands of drone operators to make this a reality. Imagine seing nothing but a darkish sky getting closer and closer than unleashing a fury of missiles down the Naval pacific fleet. Imagine convoys of marines having to deal with this shit. It's scary but my bet is china is quite now, but planning some biblical shit.
