But you have to factor in deliberate effort already to eliminate the CHIPS act by Congress. I'm sure it will get the axe in the new administration.
The rush had been increased because of the efforts Western governments like the USA have made to prevent China from getting the chips from Taiwan, that encourages the Chinese to develop their own capacity but also eliminated the hit they would take if processor production in Taiwan was crippled by conflict.
The actual ace in the hole protecting Taiwan is the fact that the Chinese want the Taiwanese to join willingly, but if the Chinese economy has continued trouble than Xi will be under pressure to demonstrate strength and that is where they could make a move on Taiwan.
I think you nearly overestimate the appetite of the USA government or people to engage in such a massive conflict over Taiwan. The new administration has made it clear support for Ukraine is on thin ice and a deal can be made with Russia to end the fighting. Why not with China as well?
