speaking as an amateur, I believe the USN is facing a real dilemma in the Taiwan Strait and SCS.
sure, the USN is number 1 in the world right now. USN can sail anywhere in the world with impunity.
But, it has never fought a strong and determined peer before.....
China's plethora of anti-ship weapons are real threats, while the USN's defense against them exists only on paper, and untested.
should the USN come to the vicinity of China to fight in a time of crisis and face those real threats?
sure, it might win, perhaps a pyrrhic victory at best.
but it might just lose, and lose mightily. ( 2-3 carriers lost to ASBM ) then America can kiss Asia, and its global hegemony goodbye.
it's a huge gamble, with very high stakes at risk.
my personal bet is that the US political elites won't take it.
