And if this is allowed to happen without any dire consequences for America and Taiwan then what good is the so-called Chinese warning if it's essentially going to be revealed as nothing but hot air. Also, what would happen to Xi Jinping with respect to his inability to even muster any semblance of military move against what China has always deemed as it's Redline. He would be severely weakened internally, and possibly be replaced which would again be viewed as a very positive development for the Sino-American relationship.
The shift in leadership could be used politically in America as a gesture of goodwill (capitulation) from China, which would be trumpeted not only as an American Victory but a vindication for the Biden strategy, and to Biden himself along with his acolytes namely, Blinken, Sullivan, and that Indian-American who's part of the NSC and wrote the book on China's long game.
If that were to happen, then China should just drop any pretense of trying to take over Taiwan or trying to create an illusion of multipolar world. It will simply show that Chinese leadership has place the economics above national interests, and that it's supposed core principles are always negotiable. A fact that other countries would ceaselessly exploit to China's detriment.
