Yet you said:

>China/Russia/whoever can send whatever they want into US airspace and there's nothing that anyone, including the military, can do about it.

So it's not "whatever they want", it's cheap drones and balloons. You make China out to be some scary powerful Boogeyman (which requires the USG to invent alien stories as a cover) and then admit they don't have such capability.

I personally am not scared one iota about Chinese aircraft threatening US airspace. And I am very confident that if such a scenario did arise, the US military would address it in the most appropriate and effective way. Which could range anywhere from ignoring it, to neutralizing with extreme prejudice.
