US warmongering has forced China into a "delete America" program with critical priority for chips. In the short term, this harms humanity and US dominance through lower market access, and lower US R&D due to less market access. In long term, it harms US dominance by forcing China to surpass them.

Allowing an enemy to produce critical parts was also a non-starter for the usa though

Enemy is entirely US's choice. China did not deny PPE to US during covid, even if demand was larger than supply rates. Now that covid is over, PPE is imported from China again. National security can mean subsidies to allow factories to be ready to shift/ramp production, not because other nations have to be enemies, but because demand could skyrocket, and government could care about US lives. Manufacturing an enemy risks those lives.

US weapon systems rely on Chinese electronics to this day. Destroying US clean energy and EV sector will destroy domestic supply chain expansion, and retain Chinese dominance over US weapon systems, and future economy. A pure propaganda misinformation system for warmongering evil is no basis for progress or sustainability, or recognizing weaknesses that could have time to fix.

But war on China move I referred to was banning sales of US patent protected fab equipment, and advanced chips to China. That is the harm to western innovation that dooms it from loss of access to world's largest electronic device market. Though in the long term, humanity will be benefitted from the competition from China. Just US stock market/companies will suffer from the policy.

Enemy is entirely US's choice

China threatening taiwan is not the usa's choice.

China's consistent copyright theft is not the USA's choice.

There's plenty to say on both sides of why they're enemies. Do not spout lies that portray china as innocent please.

"Copyright" theft. Hahaha.

"Please agree to obey our rules controlled by our corpos."

It's an actively hostile act, regardless of what your beliefs are on the copyright system.
