Actually, they have the best proxies to face against China (sorry for reply to an old post). And if the war occur, The United States will get a very big benefit for that. Because beside they can reduce China's economy and industry (as they can bomb China mainland and China will difficult to do the same to the US mainland), the war will also destroy the East Asian industry and economy as a whole.
Because the US will definitely call South Korea and Japan as their proxy. Mean, these two countries will be legit as bomb target by China. Thus, the two countries' economy and industry will get affected too, if not destroyed (as their land mass is too small to protect the whole industry area)
With everything that happen in the war, China economy will reduce, Japan and Korea will also destroyed. Thus, US get the benefit because they will become the only country that industry and economy untouched by the war.
I say, good strategy.
In any SCS conflict scenario, SK and Japan would be further away than China, so would offer little in the way of pivotal support. SK especially does not see the SCS issue as a major concern, so it would be very unlikely for them to want to get involved.
In addition, strikes against target on the mainland, especially civilian targets, will be seen as a massive escalation that will force a Chinese retaliatory Strike.
Such strikes do not have to be purely conventional military either, or strict like for like. So, China could launch cyber attacks to destroy critical US infrastructure like power stations; make damns open the flood gates to cause flooding etc; and/or China could simply got for MAD in space and systematically blow every US satellite, military and civilian, out of the sky.
US retaliatory strikes will wipe out Chinese satellites, but since the US military (and economy) is far more dependent on satellites than the China's, Beijing could easily see that as a big net positive despite the heavy losses.
That will shortcut everyone onto an extreme escalation path that could easily end with total nuclear war, which not even Trump will want.
