US missile defense defense in the Pacific, let's be clear, is also Anti-China. THAAD in South Korea? The Chinese are absolutely right with their complaint. Of course it would defend US troops in South Korea. If the US puts THAAD and Aegis Ashore in Japan, it would be the same.
Between all of those, plus Ground Based Midcourse Missile Defense on the West coast, that's more than enough layers to cut down China's deterrent.
We've essentially defanged China in this regard, which is why we don't enter nuclear treaties with them. It really doesn't do them any good.
