Thanks for that. To be clear, I'm don't feel that I disagree with you. A little over a year ago I wrote a lengthy piece about how unlikely it was that China would do anything militarily about Taiwan in the near future.
My point is more that recent actions by the USA do not seem to have reduced the potential for a conflict with China, and may have increased it. You've probably seen the reports that General Caine has some reservations about even a single conflict with Iran, and USA also seems bent on maintaining significant naval presence in at least Caribbean as well. Hegseth may have more authority, but certainly less awareness.
Personally, I see those estimates as a bit conservative and maybe a little dated, especially considering recent actions by the USA demonstrating its basically complete reliance on China for so much. The problem for the USA would not be from short-term conflicts, but prolonged conflicts. Especially with the escalating national debt, it's not clear what percentage of the US population would support such a conflict in what might appear to be the interests of a foreign population and the coroprations supported by the fabs (yes, those are also the interests of the American people, but I'm not sure how many would be conscious of that fact).
While I don't consider myself very well-informed on these issues, I feel that I should state that I used to work for fabless semiconductor vendor Xilinx, I spend most of my time in Asia (and meet "interesting" people while flying through Taiwan), have been to China twice, was married to a PRC woman for 18 years, and have been paying attention to relevant issues for at least 25 years. Internationally, relative to the USA, China is actually a very peaceful country militarily. But China considers Taiwan to be a domestic issue, and the USA has been showing some weakness recently, for example around its currency/debt, supply chains, commitments to foreign nations, and international alliances. And then there's the fact that Trump Always Chickens Out, seems to change his mind randomly, and is also threatening Greenland, Canada, and I believe Mexico as well. I don't care to research specifics but I believe the USA is involved in other armed conflicts currently, some of which may not be public knowledge.
Again, in the near term, I don't think China is going to do anything about Taiwan except posture. China is known for playing the long game, and USA seems to be collapsing its position in their favor anyway. While I understand the strength of the US military, I would be concerned about Chinese production, chokepoint capacity, supply chains, and increasing international relations. I guess my summary point would be that Trump doesn't seem to have much understanding or strategy around anything, just a lot of blowhard overconfidence and hubris.
