Well if US doesn't want China to intervene US could just let Taiwan have their nuclear weapon in the 80s, which will completely remove Military option from China, but US didn't.[1]
I’m a staunch Taiwan advocate. But sticking nukes all over the place removes our ability to slow proliferation. And sticking nukes in others’ backyards is, well, impolite.
