> The way to reduce the risk is to diversify. Taiwan with a China risk and the US with a "US risk" is much safer than either alone.

Not really. Taiwan with a China risk means China has pressure to not change the status quo.

US with a US risk means they have a vested interest to facilitate China's imperialistic agenda to try dethrone Taiwan as a competitor in the chip market.

That, coupled with the imbecile tariff war, underlines the unacceptable risk presented by the "US risk".
