We can, we just choose not to

Because China is about to attack Taiwan, which has 60%+ of the world computer chips.

That means no iPhones, no Snapdragon (Android phones), no XBox, no PS5, no AMD (Servers), no AMD/Xilinx (aka: F35), no NVidia GPUs if that attack goes off successfully. It'd be a major effect on the US technology sector, which is where I'm employed (and where many others are employed). This is a vital economic and technological issue.

If we lose the upcoming China vs Taiwan fight, its not just like "Oh I feel bad" like the Ukrainian situation (trust me, I'm hugely supportive of the Ukrainians). But Ukraine doesn't have a major economy / export tied to the USA's economy like Taiwan does.

China has made something like 400 nuclear weapons in the past 5 years or so. They're preparing for something. The current bets are on a Taiwan invasion, which has been a sorespot for them for the past century.

I don't think China is going to use those nukes per se, they just want nuclear parity with "somebody". So its clear they're likely planning to attack USA (or some other major nuclear power), which would coincide with a Taiwan attack (USA would almost certainly rush to protect this vital economic center for us, leading into a China vs USA war). The nukes are the just-in-case option for China, its likely going to try to stay conventional.

That implies the US is trying to stop it.
