But ICBMs don't do anything besides launch nukes. The parent comment has a point - China can "harass" the United States with their materiel across thousands of miles of seawater, but America generally doesn't care. There is no Chinese threat to American airspace when both countries are thousands of miles away from each other. The Pacific ocean itself is so large that preemptive long-range shipping attacks are considered to be technologically impossible too.
And I'll even go a further step to argue that China copied the United States' nuclear scheme to be deterrent rather than aggressive. Their ICBMs are clustered in uninhabited lands in the northwest of the country, forcing potential aggressors to either nuke China's nukes or strike fast enough that China can't respond. The goal of China's nuclear program, it would seem, is not to enable a panoply of tactical effects like the US or USSR, but just to remind the world not to attack their soil.
