WW3 would not be sanctions rivaling those Russia are under. WW3 would be zero trade, submarines sinking the shipping etc. What Russia is under is just sanctions, not real war measures.
Maybe. It would certainly be good for Intel if Taiwan's and South Korea's microchip manufacturing were destroyed. They'd have a near-total monopoly, like int the 90s.
But it would be incredibly stupid strategically.
I think only sensible path is to give Taiwan nuclear weapons. It removes all the dangers for ever.
