Im asking you the same question again - why the semiconductor production in Taiwan supposed to stop after reunification? Is there any evidence of Hong Kong economy collapsing after being reintegrated into Chinese economy? Any evidence of massive insurgency in Hong Kong against Chinas rule? I do recognize its not the best parallel but still...
You need to understand how the semiconductor industry works. TSMC in Taiwan manufactures the most sophisticated silicon in the world. The US designs the most sophisticated silicon in the world. The US banned China from using US IP, so have been excluded from using chips with US IP, and China is a decade behind in silicon design.
I will repeat my initial point - unlike Taiwan Russians dont have to rely on the rest of the World in order to defend themselves. You know Ive been listening the stories about Chinese taking away Siberia for at least 20 years now. Im not joking. Just like the stories about Russian economy collapsing because of Russias bad behaviour. 20 years has passed and neither is the case. But its alright you just keep dreaming, guys... ???
