On more than 30 occasions, the United Nations Assembly has discussed the blockade against Cuba, which costs the island 5 billion dollars annually, according to some estimates. Every year the resolution is proposed and the whole world, through the vote of the absolute majority of the member countries of the United Nations General Assembly, has condemned the imperialist attitude of the United States towards Cuba.
The problem being that Taiwan is a critical part of the entire global economy. TSMC fabricates ~50% of all semiconductor products in the world, but critically >90% of all fabrication at 5nm or lower (basically everything with a fabrication process less than a decade old). They are the leading edge. If you want to make a modern CPU, TSMC is your foundry.
By threatening Taiwan, China is holding a gun to the head of the entire world. Loss of TSMC’s fabrication would basically shut down the global computer industry.
You are just giving more reasons for China to do it.
