I think there's ample evidence against that hypothesis. Cost overruns and project cancellations abound in the US MIC. From Minutemen nukes to fighter jets to hypersonic missiles, nothings is really going right. As we saw in West Asia, the USA doesn't even have enough body armor for its forces, and it certainly can't care for its casualties. There's really no way it's going to win a war that it has to go literally to the other side of the planet to conduct. It will be so heavily dependent on vassals, like The Philippines, Japan, and occupied Korea that every single thing it does will be done in a way that is completely fragile and smothered with paranoia if not constant sabotage.

As far as I'm concerned, all the military strategists who believe that the window for winning a war against China is closing are only taking into account paper capabilities and not taking into account the USA's inability to actually produce, maintain, and deliver those capabilities in a sustained conflict. To me, that means the window is likely closed. Then take into account that both China and Russia have been very successful in counter-intelligence and the intelligence fiasco that is Ukraine and I don't think the US military strategists are even working with an accurate picture of China's capabilities and capacities. I fully believe the window has closed and it's just going to take some time for the reality on the ground to reach the strategists.
