The US stance is it acknowledges that China believes that Taiwan is part of China. That is the equiv of saying “I know you think the sky is green, I just don’t share the same opinion.”
The US’s position is that it’s up to Taiwan to decide its own fate. And will not allow china to invade and force Taiwan to join China.
This has been the same position for the last 70 years. Taiwan has been an ally of the US long before the CCP was created.
Doesn't seem like USA is respecting anything.
