Airfields, same as those nifty little man-made islands of theirs, are nothing more than impossible to miss targets for all sorts of long-range missiles.
China has no real durable force projection capability. Quite probably never will, either. And the clock is running out quickly on time they have left to play these stupid games.
The entire Chinese gambit requires a complaint US leadership and media. That’s evaporating as we speak.
And that’s a good thing because our current crop of depraved degenerates masquerading as flag officers in the USN are doing everything they can get away with to destroy our USN.
