The thing is they do not, they don’t know how to make the equipment or the materials. It’s like if they bought a disassembled bike from Amazon, and then claim to be a bike manufacturer after putting it together. It would take espionage and decades of development to reach Taiwans level. I said this in another comment, this stuff is not developed overnight, it’s a monumental undertaking. India tried and failed and the US is now spending billions to bring fabs to the US and they will have to do it with the cooperation of Taiwan and it will take years.
