Chinese planners should be aware that the US is using the Ukraine war not just to get rid of old inventory but also planning how much munitions they would consume in the coming war against China, and tweaking data for their own platforms under EW attack by Russian systems
I see it as an attempt to rebuild industrial capacity as a whole, but specifically military industrial capacity. They seem to be talking about not just multi-year buys for things like missiles, patriot batteries, radars, but also increases in production capacity. They are also investing in things like new docks for ship repair and building.
These things are going to take a long time to bear fruit and there is no guarantee they end up making large contributions to military industrial output due to the vagaries of funding from Congress.
If the US has any realistic Taiwan military contingency plan I don't see it being ready before they have time to mature and expand production capacity.
Personally, I don't think there is any real appetite for US Military intervention in a Taiwan straight conflict. I think they would look to leverage economic and political pressure and isolation to hurt China, which could hurt China much more in the long run.
