The US does recognize the strategic importance of semiconductor manufacturing and spends billions on it each year. Many devices for markets like aerospace and defense are only manufactured domestically. That said, the US has a defensive pact with Taiwan and to attack the island would be to start World War 3.

Look outside the US nuclear umbrella and NATO to nations not friendly with the PRC - who among them is wealthy enough to start a chip industry that can compete?
