Our "one China" policy insinuates that Taiwan is a part of China anyway. The UN does not recognize them as a sovereign nation and we have no embassy there.
Our "one China" policy is just plain STUPID. A military incursion by the CCP into Taiwan will be a civil war by our own standards, with Taiwan being the rebel state.
I guess some of our brilliant (sarcasm) civil war historians here will call the Taiwanese "traitors" like they did the soldiers of the confederate states. And I suppose we will be enablers of that traitorous behavior.
