I think the problem with Intel's foundry is that it cannot produce the same quality and quantity at the level of TSMC.

I was looking through the list of fabrication technology for the latest CPUs, and while they say they are 3nm, it is using TSMCs technology (Arrow Lake S: Fabrication process: Compute Tile (Contains the CPU cores) TSMC's N3B node.)

My guess is that Trump is trying to save Intel by forcing TSMC to buy them under the guise of "I'm forcing companies invest in the US".
