With pure logic, Axis of Logic Reader, China Lee responds to China warns US to stay out of maritime spat:

Proximity must not supersede historical title

During the 1982 Falkland Islands War, the United States rejected Argentina's argument of physical proximity. Instead, the United States supported British military efforts to assert its historical claims of discovery and sovereignty over the Falkland Islands.

Similarly, the United States should publicly announce its support of China's 1,000-year-old historical claims and territorial sovereignty over the South China Sea islands and area. If the United States fails to reinforce the international-law principle that historical title trumps proximity then the world will degenerate into chaos.

If the Vietnamese and Filipinos are permitted to encroach on sovereign Chinese South China Sea territory then the Argentines will be encouraged to launch a second Falkland Islands War. Also, the Spaniards will use the proximity argument and militarily attempt to eject the British from Gibraltar. The Turks will grab the nearby Greek Dodecanese Islands. Last, but not least, the Moroccans will try to seize the proximate Spanish territory of Ceuta.

Wars will break out all over the world if proximity is permitted to supersede historical title.
