The risks don’t outweigh the potential benefits. Building a functional nuke isn’t an operation with a couple of laptops and internet connection. Also, Taiwanese economy is extremely tied to China. Things aren’t really black and white here. It’s not like all Taiwanese hate all mainlanders, nobody flies between countries and etc. Supermajority of people actually support status quo, rather than aiming for complete independence. It’s not an easy thing to balance.
