How does this work at sea? I don't know much about how aggressive (or not) "freedom of navigation" operations really are. They don't appear to be too friendly in the Strait of Hormuz or the South China Sea. However it is supposed to work and however it does work at sea, is the situation similar for space? > What if countries decide to extend the airspace to the aerospace? I imagine the US would consider it an attack and retaliate (maybe economically, militarily, or covertly) against the "attacking" country.
