Highly recommend the economist’s podcast on Xi called ‘The Prince’ Xi became a Leninist and is trying to be the next Mao. He is a true believer that his glory and the glory of China can only happen by taking back Taiwan. TSMC is a huge reason for this conflict. The current US policy is trying to slow China’s technological might for that next war.
But China doesn't actually have a lot of technological prowess on their own. The USG might be trying to slow them down but they're not concerned about China militarily. I worked for a defense contractor back in the early 2000s when the USG was selling a lot of arms and systems to Taiwan. I got to see the bullying in person via the ASOC (part of the C4ISR platform) system we were installing. China would routinely fly…
The one thing that matters in the long run is money and even though the US is fighting tooth and nail to halt China it isn't very likely to happen - who knows, we'll see. Whenever this discussion pops up it reeks of racism. People from China aren't less intelligent than people in Germany or in the US so with time and more money they will with 100% certainty overcome any technological gap. Sure they are behind in some areas but pretending they can't make a pen is disingenuous. They have had the capability to launch satellites since the 1970's and are now building a space-station. It is no different than saying the US can't make rockets because they had a lot of outside (Nazi) help after WW2. China has in a very short time-span gone from mostly agriculture to being in the top three in many (most?) high tech areas.
But in short can you explain why the US is using insane amounts of energy to slow down China if they are so totally incapable? Why do we need a completely new doctrine and pivot of the navy to be sailing around an utterly incapable and un-concerning China?
