It's an interesting idea, but it would amount to calling China's bluff. China has stated that they would definitely commit to a ground invasion of Taiwan if the US recognized it. The question is -- how serious are they about that?
Personally, I think they'd go for it. They've been itching to take over Taiwan by force anyway.
You can’t compare Afghanistan and Taiwan. The US never really cared about Afghanistan once they got rid of Al-Qaeda and Bin Laden. They only stayed as long they did because the optics of leaving were always going to be bad.
The US does care about Taiwan, because of real economic interests.
Absolutely not. US troops in Taiwan create a long term issue. It's objectively better for China to strike Taiwan before there are sizeable troops there than wait for those trooos to accumulate forever.
China would strike as soon as US troops officially settle in China in a military and not police/security/training/sales capacity.
