Not only has US never endorsed their claims outside Taiwan
You keep pulling shit from your ass. The US has formerly recognized the ROC and all its claims, then put the PRC into UN instead in the cold war to get them on their side. And recognized the One-China Policy.
Now, if the US is again violating the One-China Policy, that means they deal with ROC as a state again. Here you start to pull out without sources or proof an assumption that there is an imaginary state called Taiwan, with a constitution with claims only about the island itself, and that the US is exactly protecting this state, which I said does not exist in that form.
My whole point is the absence of that nuance, and that this state the US de facto recognized has claims worse that any other country in Asia.
They dont support RoC’s constitution
I mean yes now they don’t recognize it officially, but they and the government on Taiwan do not make any considerations regarding these claims, they just still have them? That is literally my whole point.
“Immovable Object: North Korea’s 70 Years At War with American Power” by A.B. Abrams comes to mind. It mostly uses Western or SK sources and documents published/declassified and the resulting picture is so cruel you won’t sleep for nights
