It is really unclear why you think that either the political interest or strategic logic of not wanting to rely on manufacturing in China, and having some on the value being created here goes away, or is some idle whim.

Sure, if it took decades of slow patient effort to create the current situation, it might take decades to unwind it. And, sure, the US political system is exceptionally bad at industrial policy.

But, at the end of the day, the political and military logic is, and will be for the forseeable future, get your supply chains out of China. Just because it is slow and difficult doesn't there is any reason to believe the pressure will relax. (Putting aside the possibility of an AGI/robotics revolution)
