gollark: Fear it:
gollark: (Taiwan holds basically all leading edge semiconductor production and I believe a lot of the older stuff. Invading could physically damage it in hard to fix ways, and would probably lead to the loss of most of the people working on it and their knowledge; even ignoring this, it relies on materials from elsewhere which could be cut off. Basically everyone needs the chips produced by TSMC, and if they just stopped existing so would... roughly all consumer electronics for several years.)
gollark: It would not.
gollark: I don't think they can actually militarily do anything to Taiwan without imploding the entire world economy for several years.
