A freaken Reef is just a tiny rock and many time submerged in high tide and only show up during low tide.
If you consider these tiny Reef as Vietnam power in Spratly, then I cry for you!
Do you knows Island holding by PLA are large enough to have airport that can supporting jet fighters.
Like I say, PLA can dislodged all these Vietnamese and Philippine soldiers within 48 hours of the start of fighting.
Don't making us laugh here; you want to see some PLA base inside Spratly Island group?
