Is that really an honest question? Because it looks like a setup for some trollish "hurr Intel doesn't count because they're stinky" nonsense. Yes, America makes chips. Always has and never stopped. Even of you don't like Intel, America's chip production is obviously sufficient for national security intents and purposes.

Intel still has fabs in the US, TSMC is building more fabs in the US. TI also makes chips in the us. The capability is there, but it's also interlinked with a global supply chain for silicon and other things.

So can the west make chips without TSMC? Yes. Very much so. Can the US make chips on their own, in a more limited way.

Intel is struggling, TSMC found it extremely difficult to set operations there, that doesn't smell good. For >20nm chips sure, for bleeding edge that's yet to see.

Yes, in many places.
