the point is to not give US/west and their allied gang the easy convinced reason to encorage their normal citizen support starting ww3 , war with china in the first placeThis is unnecessary. The moment shooting starts, all those fabs are as good as destroyed. Lithography machines are extremely delicate and fragile; without constant power and inputs, their components degrade and become useless.
if you let direct shooting between china and US/west happen then the TSMC shield already did it job well , destroy it or not after that moment doesn't matter
