Hainan Island:
That’s where the US EP-3 was forced down after a mid-air with a Chinese fighter about 10 years ago. The USN was interested in the island cuz it’s been hollowed-out a bit for a huge and well-protected offshore submarine base.
Some say the Chinese have plans for 20 submarines to be based there inside that island.
The Chinese want oil, they want their sea-lanes protected, and they want the USN out of the West Pacific.
You are correct, but it aint gonna happen.
