Given the range of Chinese & Korean (NK) rocketry I think that the defensive line needs to be further out — like Australia. The Philippines won’t be housing any major bases unless they are Chinese.
read the Congressional Research Study on the Chinese Second and Third Island Defense Chain. Second includes Guam. Anderson AFB is a major target. Hawaii is in China’s Third Defense Chain.
China is using the same UNCLOS to tell Japan it can’t have Okinotorishima Shoal, yet is ignoring the UNCLOS over Scarborough Shoal.
