"The Pentagon Is Freaking Out About a Potential War With China" - https://www.politico.com/news/magazine/2023/06/09/america-we...
"...But a swift response may not be possible, in large part because of how shrunken the U.S. manufacturing base has become since the Cold War. All of a sudden, Washington is reckoning with the fact that so many parts and pieces of munitions, planes, and ships it needs are being manufactured overseas, including in China. Among the deficiencies: components of solid rocket motors, shell casings, machine tools, fuses and precursor elements to propellants and explosives, many of which are made in China and India..."

You need to stop reading into sensationalist headlines and actually understand the strategies at-play here. This is about creating sufficient conditions for China to not invade Taiwan, not blowing each other up in a second floating Ukraine. China doesn't want that, Taiwan doesn't want that, and the United States doesn't want that either. The critical difference between posturing and realpolitik is actually doing something; China will refuse to commit to a violent invasion unless globalism fails them (hint: globalism never fails China).
The parent's line of logic is sound; the United States has fundamental interests in securing Taiwan's independence. They are one of the very few countries that would receive Israel-levels of international intervention if their sovereignty was threatened, and China knows that. A ground invasion under current conditions would be political and materiel suicide; you have to imagine apocalypse-level global malcontent before NATO would roll over and go ahead with China's reunification strategy.
